Just what I've been waiting on & great job. I was all but about to have you'll flash my 2017 GSXR 1000 last yr. But decided to wait to see what you done next. Glad I did. I'll be in contact here soon

[@avalon1734]

Thanks Brock. You proved my tuner knows his shit. When I took my K7 Gixxer 750 in he told me to keep my PC3 to tune with the flash he did. He gave me the graph showing the bike when it arrived, after the flash and after the flash and PC3 map. Hell, he even emailed the PC3 map in case my PC3 ever fails.

[@Tunnel_Vision_Moto]

I love the passion that you have for this and that you don’t give up when things may look the best but you make them even better. You squeeze as much power out of these bikes as much as you can!

[@twistandgo3414]

Great video, thanks for the time and effort in producing and uploading it. I've been wondering whether to go ecu flash or PC5 on my 750. seeing this, I think I've decided PC5 for my requirements will be just fine. Yes, maybe a touch more outright power from a dedicated ecu flash but its going to be negligible gains over a Pc5, that will also be custom mapped for my bike anyway. Great video.

[@kmotorshop]

My gsxr1000r 2017 sometimes the auto blip doesn't want to blip from 6th gear back to 5th. Sometimes it will double blip. What should i do? No error codes were found at all. Only happens from 6th gear back to 5th and from 5th gear back to 4th gear. Best auto blipping only happens when The RPM is higher than 3500. Very rare. Is it a Voltage drop situation? Thank you from Thailand.

Sounds like your chain is too loose - when this happens, the resulting backlash will not allow the shifter to function properly: kzbin.info/www/bejne/Y5TKeHpoi81qp8k

hey Brock love your videos first off. but I was wondering if you might be able to help me with. I recently bought a 07 ZX10R it has what I believe to be a Gen 1 ZX10R exhaust from you on it. is there anyway to truly tell.

[@BrockDavidson]

@Jeremy - our customer support staff can help you with that question: [e-mail]

[@apexhunter2k]

Brock Davidson Hey Brock. When you receive the new recalled ECM did you just download your same Flash with the power commander of the previous ECM that you already made or did you create a new Flash and map for the new Ecm. Also can you explain more about the studded in gears 2 and 3 because I never felt it on my bike when riding. Did it show up everytime you did a all gears run?

[@BrockDavidson]

apexhunter2k - the power commander import did not and still will not work. We had to alter the new (post recall) ECM image to match our previous modifications/tune. The bike would not studder every time - it made a very strange sound. The dyno chart is available here: brocksperformance.com/content/brocknm/PDFS/GSXR1000_2017_Post_Recall_Test.jpg we suggest everyone obtain the recalled ECU.

[@ichista]

Favourite current series on KZbin thank you for sharing Brock

[@robskavberg4285]

Can you explain why @5:50 we see the map numbers jump from 16 to -5 within 250RPM? I would expect to see much less variance between numbers and see a smoother transition. Fantastic series btw love your work. I have a 2010 gsxr 750 with straight pipes (no cat), M4 and a power commander 5. I bought it with a dyno tune on it with a custom map but I am not sure if it had a custom ECM tune as well (have the printout though). - just looks odd when I see the trim numbers change so drastically.

[@robskavberg4285]

Also, can you explain how the gsxr's have a power mode switch (A/B/C setting) affects the maps/AF ratios? - I am unclear what the power mode switch actually does. (retard timing?, change AF maps?) My spider sense tells me that if you muck with the modes it is going to affect the air fuel burn which is going to throw the map out because the map is tuned for a specific config.

[@BrockDavidson]

Large jumps in small rpm's are required to keep the AFR correct throughout the range. This is common when a precise AFR measurement, under load, is observed. This doesn't happen in the stock ecu mapping... Which is why stock ecu mapping works so poorly. If you add a wideband sensor to your pipe and go for a ride, you will see the same results, once corrected.

[@robskavberg4285]

@@BrockDavidson Thanks Brock! I have rebuilt many car engines from full tear downs but the whole Air fuel thing was a complete mystery to me.

[@mikeskidmore6754]

Very interesting Video .. I installed a Boon docker fuel controller and an Oxygen gauge on my Yamaha snowmobile because it ran way to rich stock .. My Boon docker does not control timing but a 4 degree offset keyway really improved my MPG and HP by just a little .. It's an R-1 engine that turns 10.500 RPM .. It's great to know how close stock timing is to perfect . I have never worked with electronic fuel injection so of course I wondered how accurate and close the controls are how precise the injectors are ect.. there must be a lot of variables in flow .. I deal would be 4 oxygen seniors 4 spark knock sensors and active tune controls for each cylinder.. Seems an onboard Oxygen gauge would be handy .. Looks like your videos make a great sales pitch for the active tune system... For a street bike it seems like you can have the best of both worlds great wide open full power yet could cruising mpg .. Your first gain of you explained is to get away from being too lean as stock bikes are..

How about changed the Secondary injector balance map ? Would be interesting , the woolich software looks to be slightly ahead of the flash time with auto tune etc

[@BrockDavidson]

We changed it - we would have to get out of my 'comfort zone' (40-50%) to get anywhere close.

[@peterago1082]

Hi Brock had no idea that an imported fuel tune from PCV would be so different inside the ECM, thanks for the knowledge and video again

[@BrockDavidson]

@peter - The imports aren't usually THIS bad (as mentioned, this bike is a special case). That said, I haven't found one that will drop in and meet our standards. (not even close, in fact)

[@MrBCRC]

Yeah this is an old video but I've just bought a woolich programmer/logger and am in the process of tuning my own bike. I'm technically minded and the systems are pretty straightforward if you're patient and dont' change things without understanding the impact. I like that you're honest about the power commander vs flash situation. I also like that you're honest about the time it takes to develop a good flash map but that it's also worth it in the long run. Luckily for me with woolich specifically I can just ride around with the logger plugged into the bike and then load it into the software and adjust based on the logged AFR readings. Once people start to realise that these systems are as easy as a DIY oil/filter change and less complicated than throttle body syncing we might find more people prepared to go down the DIY route. Especially those that do their own servicing.

[@BeginnerMoto]

Do you do anything else to modify your results from the auto tune? I have the same setup on my gsxr but I didn’t really find good instructions how to use it. I’ve just been playing around with mine and my bike works fine but I’m not sure if I’m using it right.

[@MrGuerraTube]

Hi Brock... i've been watching from the begining and starting on the 190hp, passing by the 204 and now 190 again it sounds kinda strange... however, it's not all about HP... i noticed you never mentioned anything about torque, it is because you don't find it relevant for your tune or because you simply decided to ignore it...?

[@BrockDavidson]

@MrGuerra - we have mentioned torque as the force that accelerates the vehicle from the beginning of the series. That said, we find that it's not easy for the average person to relate to this increase. In episode 2, we made 165.73 RWHP SAE- in E7P2, we are now at 194.14 RWHP SAE (an increase of 17.5%). It's fairly easy for most to understand that we now have a MUCH faster motorcycle. If I told you that we gained 6.19 ft-lbs of torque (a 7.5% increase) over that same period - would you understand this to mean the EXACT SAME performance gain? We will get into torque multiplication, and it's benefits (or downfalls) in more detail once we get to the drag strip.

[@MrGuerraTube]

[@turbotyoma]

Brock, I just love your channel! Watched twice, but still have a question. Maybe misunderstood something. How do you understand actual throttle blade opening on ETV bikes? What does TPS percentage in fuel map mean? Throttle grip or ETV? Thank you!

[@BrockDavidson]

@Турбо Тёма - Great questions! If the bike is throttle by wire - aka has only one set of throttle blades, the easiest way to read the blade angle is by viewing it through a power commander. If a PCV is not on the bike, you must configure a 0-5v analog input to measure (not easy for most) - our use an OBD2 reader (either handheld or through dyno input) TPS means Throttle Position Sensor - this is the blade angle on single blade/throttle by wire applications...not to be confused with grip angle as the ECU overrides rider input in these applications unless the ECU is reprogramed to ignore the override. We call this derestricting the ECU and making the ETV (throttle Blades) 1 to 1 ratio with the grip. Hope this helps.

[@turbotyoma]

@@BrockDavidson Yes, I have already watched your 3 part where you use scotch lock connected with ETV signal wire)

Thanks Brock! Epic series. Loved all of them. Question about humidity, if your dyno room was air conditioned could you get consistent results within a small percentage? I had my bike dynoed on a humid wet day and I cant say its perfect, would the humidity have been a factor?

[@BrockDavidson]

The amount of energy needed to truly heat or cool a dyno with a smoking hot bike running inside is tremendous. We built our room inside a 12K square foot warehouse and use the temperature of the floor and concrete floor and surrounding components to help cool the inlet temps a bit. That said, in the heat of summer, that room might as well be located in the parking lot. We have seen 108 degree ambient room temps in the summer. The sensors on your bike allow a wet/humid summer map to work well year round. We do have hot weather maps for some bikes.

[@folerx]

I just buy bike K5 1000 with almost 50000 miles on it, dont know history, bike was already dyno mapped i have dyno print. Custom mapping here cost 450$. I am just street rider, enthusiast which want just that bike run smooth. For 450$ I can buy pcv and auto tune. Can you advice pcv to go or again custom dyno tune? Do you block PAIR system?

[@fabiojr15]

The 12krpm flat spot on bmw can be totally fixed with PVC? Or it does it need a flashing ecu also? Thanks In advance

[@BrockDavidson]

We can tune it to be much better than stock using the PCV, but It needs to be flashed also to try to keep the throttle blades open 100%. I say try because BMW's Bosch ECU's don't work like the Suzuki's Denso unit - you can't just jump in and tell them what to do.

[@motozest7856]

Brock, I'm a bit out of my depth here, so please help me out: @ 7:55 you show that by removing the PC out of the equation you get big power and torque holes and poor A/F ratios, and @ 9:05 you point out that you'd have to go in and live tune each cell individually (because the Active Tune was not available). In Lamb Chop Rides video where he remaps his GSX-R1000R ECU (check out kzbin.info/www/bejne/jaPQfYNqZr2ibc0 @ 3:05-5:02 and 10:39-14:24) the technician tunes his bike per cylinder - not at the tailpipe - smoothing the A/F ratio graphs out manually because of the different maps for the different throttle positions and he doesn't use any Power Commander. How was he able to do that?

Hey Brock, just came across this video and first have to say awesome job very much enjoy your videos and all the knowledge you put out there thank you sir.

Have you seen or know if there is an advantage to running a power commander in combination with guhls flash on a 14r? I will be purchasing the AH2 full system in the next few days and was just going to send my ecu back to don to have the fuel corrected for the new exhaust, now I am wondering if I should have the fueling flashed back to stock and get a PCV lol thanks in advance.

[@jockvanniekerk8074]

So brock I'm confused when you talk about the exhaust on the bmw and the gsxr you said you went with the alien head cuase your going drag racing but if you wanted more midrange torque you would go for the predator. I thought midrange is exactly what you want to be better for drag racing doesn't the midrange help with acceleration?

[@BrockDavidson]

@Jock - Great question. In drag racing and land speed, the bike spends almost all of its time in the high revs and WOT. We can make simple gearing adjustments if we want more torque or more speed. Dropping 1 tooth on the countershaft has more of an effect on acceleration than we could ever build into an exhaust. In road racing, the bike spends most of it's time with the throttle partially open, especially on short courses - this is where a broader power/torque range is most benefitial.

[@maxsarat]

Hi Great to see and learn from your video, I just have a question I have MIVV full system exhaust, PCV and Stock airfilter on my CBR 650F I dynoed my bike to see the power output which is 81bhp saw another video where in the guy has flashed his ECU and his bike is showing 96 bhp , just want to know can I still flash my ECU from the same tuner keeping my PCV also working with same. Is it really possible to keep both

[@BrockDavidson]

Glad you like our vids. Yes. As long as the fuel tables in the ecu are not altered, your pcv and maps will work like they do now. Please note, you will probably need additional pcv mapping after ecu derestriction.

[@rrrkev]

Hi Brock, great videos BTW, if I missed seeing it I apologize but does disabling the "deceleration fuel cut" smooth out any off/on snatch in the throttle response ? Thanks

[@jryer1]

@Brock - I don't know too much about drag racing, time to peak power clearly in the GIxxer's favor, but does that mean the BMW would be catching back up at the end of track, all other things being equal?

[@BrockDavidson]

@Getis - Our GSX-R 1000 currently tops out on the dyno at around 183 MPH (OEM tire/gearing/peak rev limit, etc) The BMW will run @195 MPH with the same set-up. It would also depend on how long your 'track" - the BMW's speed would show up in a standing mile - not in a 1/4 mile.

[@blawrence6992]

First off I hope you made it through the Tornado and storms without damage. How confidant are you that your method of tuning (single O2 probe) is accurate on all 4 cylinders given the fact the Suzuki has two different intake horns. Would monitoring each cylinder (or at least 2) to get a more accurate view of O2 be required with the additional flow? I ask because I’ve seen a tuner that found very lean cylinders yet the single point O2 appeared correct on a piped de-restricted bike. I have your Predator and PCV on my 2018 and it runs great, so I’m happy. I only ask the question because I see how methodical you are at tuning, and I figured you would “leave no stone unturned” on you quest for perfection.

[@BrockDavidson]

@B Lawrence, Thank you - closest tornado was about 1 mile north of Brock's, we are fine although two Brock's employees were in two different tornado. Shaken, but healthy. We have not actually 'tuned' yet. We have dyno tuned, but that is a static application (bike not moving) - we will tune dynamically (moving) as soon as the chassis and gearing will allow for 3 consistent runs in a row. Once that happens, we will use the drag strip to quantify performance tuning theory/results. Please see this for more info: blog.brocksperformance.com/faq/how-can-brocks-get-mapping-so-close/

[@Mbee16]

Hi Brock hope you are well. Suppose you have a Power Commander V with map selection. Suppose you create a fuel economical map and performance map. How significant would the fuel savings be for a litre bike of you were to make a leaned out low performance map?

[@BrockDavidson]

That depends on the bike. For instance, the H2s can see a big increase 10+ mpg. Where a normally aspirationed 1000 might only pick up a couple.

[@Zbeeeb]

Hi Brock, I own a 2015 ktm superduke. I left the stock headers but I replaced the catalyser with a link pipe and I have the Akrapovic slip on , I saved around 10 pounds ( 7 pounds from the catalyser and 3 from the slip on ) I didn’t replace the headers because It was way cheaper to take off the cat then to buy the 2 grand full line. I also removed the stock air box and installed the Rottweiler air box ( way more air comes in ) I installed a power commander 5 and an ignition module and had it tuned on the Dyno. I do feel that the bike is more powerful but I find that when the weather is hot and humid the bike doesn’t perform as well ( not even close ) to when the weather is cooler. Do you think that installing an Auto Tune would fix that problem? Another Question: do you think that the setup of my exhaust without the full Akrapovic header was a good idea? I mean do you think that the Akrapovic headers would have increased the performance? Cause in my point of view it basically ends up being equally the same. Thanks

petelpete - headpipes are the part of the exhaust that improve horsepower - a slip-on improves the look and sound. As far as hot/humid weather - some bikes compensate for it better than others. You can create your own -5% across the board 'hot weather' map and select between it and the map you are using by installing a map selector switch: brocksperformance.com/dynojet-map-selection-switch-power-commander-v/ if you had your bike tuned by a competent tuner, you should not need an autotune unit.

Hi Brock, my local tuner in the UK keeps telling me to go the ecu flash route to sort out the fuelling etc, In your opinion is a Power commander the better route or should I go with the ECU remap? Thanks Mike.

Hey Brock I have a 2019 Honda cbr1000rr sp1 . Pretty sure my speedo is running off wheel sensors and imu ect ect. I'm changing my gearing up two in the rear. Will this interfere with my electronics or throw a code? Pretty sure your gsxr is running off wheel speed sensors also and you changed your gearing.

[@BrockDavidson]

It can. We have issues with the ZX-14R that must be solved with gearing changes, otherwise the bike develops a strage miss. I believe Guhl Motors has a flash for your 2019? Give them a call.

[@peterwong94]

Hi Brock, I’ve been following your stock to brock series very closely. I’m currently working on a 2017 GSXR1000R with Bazzaz ZFi & FTecu flash. I’ve taken a look at the throttle plate mods which is already in place for the ECU number I’m using so I’d be expecting not much power gain from a base run I did on the dyno. As mentioned earlier, the bike is running on Bazzaz ZFi, FTecu flash (EU flash), sprint air filter, decat with SC project end can. Do you know as to why I am not able to achieve a power gain despite the above? Stock: 168-170hp

[@will160176]

@Brock Davidson does this bike have a knock sensor? I went back and looked at FTECU unrestricted map and it has many small changes in the ignition timing. Im 240lb rider and I absolutely have a hard time redlining it in 6th with every mod in this series (almost) and theres many, many videos of people grabbing this bike stock and easily rev limiting this bike in 6th... easily achieving even a top speed of 301km/h 100% stock. My friend has been working on stuff for a long time and I went over a long conversation about this and he suggested because of the advanced ignition timing it could be knocking and the knock sensor limiting the engine making it hard to reach rev limit. I'm really not sure why they have advanced ignition timing in their basic unrestricted map for download... The only thing I wanted was open throttle blades and no top speed limit. That's my other question. Will it have a top speed limit of 186 if I change the stock maps manually and ecu settings myself? I don't see an option for top speed limit in the files anywhere so im not aware how they do that. I'm pretty sure the cluster is locked to 186mph also?

[@BrockDavidson]

@william. The bike does not have a knock sensor - Per our videos, our mapping also does not include any ignition timing adjustments. FTECU should be able to help with your questions regarding changes to their maps. If you have questions about using Brock's Products, please feel free to contact me personally at [e-mail]

It's not Dynojet... It's Euro 4. The bike throws emissions/tamper codes that can't be easily erased - the flash will turn off the light. The codes are still present, but not a nuisance to the rider. A square of electrical tape might be just as soothing to your customer ;)

[@megaseg100]

Sorry, in this video you apply table(pcv5) to Fuel maps..but table pcv5 got only 10 columns(throtle positions) ECu flesh got so much more throtle positions(columns) so how they transform

[@BrockDavidson]

Maps average between columns when viewed as a percent. If the secondary injector percentages are the same, the map import works ok. As soon as the secondary percentage changes, the import does not work well. This is why we adjust by hand in these areas.

[@supermotodave]

With the inability to get a flash for a 2021ZX10R would you suggest a rapid tune or bazazz or a pcv or is there any way to tune through the stock locked ecu

[@BrockDavidson]

Any piggyback can help - if available and tuned properly. No tuning whatsoever to a locked ECU.

[@capiwalker]

I love your videos and im trying to learn, im looking into FTecu maps and i found that the TPS vs RPM maps on the unrestricted flash are exactly the same as the stock, as far as i knew and it looks that i was right, the only changes they do on the "unrestricted" maps are the ETV or whats called the "throttle limits" on my zx10rr, just to unleash the 100% throttle but they dont touch the ignition or any fuel maps. That brings me to another of your videos where you were working on a zx10r with Mr Guhl where you agreed that isnt the best idea to change that much those maps (as FTecu does) and he just change the top restrictions... Just want to learn and have more things clear, thanks for your videos and i hope this is a good question.

[@capiwalker]

[@danz5945]

Hi brock I check out the hole clipsession and i realy find ist interessting. And Big thanks!! I've been reading a lot of Literatur since a wile on engine tuning,... To keep it short, is there a reason why you are tuing to 13-13,2afr because all of the Literatur that i know say, that max power on gasoline is met @ 12,8? Thanks

[@BrockDavidson]

@Danz - hello and glad you are enjoying the series. There are many variables to consider when tuning - AFR is only one of those variables. We find that different engines, makes, models will all typically have different values for max power. Once the bikes ability to adjust for ram air is considered, the optimum AFR for a particular engine will typically change. Check out this FAQ for more details: blog.brocksperformance.com/faq/how-can-brocks-get-mapping-so-close/

HI Brock The FI on all Honda CBR from 2008 when started commence moving the timing forward in large increments automatically and will continue to advance untill the knock sensor detects knocking, when knocking is detected the ecu retards the timing by the last increment and then rechecks, if a knock is not detected then the timing will advance in smaller increments unit again a knock is detected. This continues untill the max timing advance is achieved and no knock is detected. This process occures each time the bike is started. It is designed to get the best advance setting regardless of fuel used, considering this, is possible to flash a different timing map on a CBR 1000rr or flashing a Honda only involves the fueling?

[@BrockDavidson]

@Sebastain - In the past we 'tricked' the ECU into not allowing this to exist by using a Bazzaz Z Bomb: www.bazzaz.net/index.php/z-bomb/z-bomb-cbr1000rr-08-14 - today, this can be incorporated into the ECU flash.

[@BrockDavidson]

@Ahmed, you can try to import our PCV map and go for a ride to see if it works better or worse than the basic derestriction map. Or, try one of FTecu's maps for a generic exhaust. The other option would be to install a PCV and make sure the base flash you are running has the stock fuel maps and secondary injector percentages.

We use Guhl's MorDefy whenever possible. We also use ftecu and WinOLS. The dynojet power vision can write to the ECU, but we don't use it for anything other than Harley's. Dynojet does not have a software that writes to the sportbike ECU's that we tune.

[@harshmkumar]

Hey brock, you use power commander alot in your vidoes. I was curious to know what is your take on bazzaz vs power commander? Just curious to know why you wouldn't use it considering it controls more injectors. Thanks for the informal video and keep them coming!

[@BrockDavidson]

We choose the PCV because it is designed to work hand in hand with our model 250 Dynojet dynamometer to create the fastest/most precise/smoothest maps we know how to make. I have never seen the need to tune the secondary injectors in stock engine applications, even when using highly oxygenated fuels. The Bazzaz unit works well for use with modified engines and general self-tuning when matched with their Z FI module. Unfortunately, low throttle openings are not tunable, which can be a hindrance to smooth operation on some bikes.

[@FirstLast-tx3yj]

do i lose my HISS or any other anti theft when i put a power commander or flash my ecu?

[@BrockDavidson]

If you are in the US, no. If you are international, you must send us your ECU to keep your anti-theft. If you purchase a pre-flashed ECU to replace your current international ECU, you will also lose the anti-theft. The PCV has zero effect on the anti-lock, regardless of your location.

[@Da-wooley18]

Brock Does your tune or horsepower change with one of your sidewinder exhaust systems in comparison to the alien head systems Or is all about ground clearance I’m thinking of making the swap on my race only busa to lower it some more But use the 1k as the example for my question

[@BrockDavidson]

That depends on your application. In a stock-for-stock (all bolt-on) application, they would make about the same power - but of course, the sidewinder can allow the bike to be lowered several more inches (As a general rule: -1" in COG (center of gravity) means @1 tenth of a second quicker in the 1/4 mile. Sidewinders can help some bikes be lower 4-5 more inches when use with a billet/lowered oil pan. Once power levels increase (above 220 RWHP or so): larger displacement, nitrous oxide etc. The sidewinder will start to pull away from the street systems in power production.

[@Da-wooley18]

I didn’t realize you could get that much lower with the sidewinder and billet oil pan set up I guess that makes it clear then thanks for the information as always keep up the good work Are you guys gonna make the mancup race at SGMP April 6-9 ???

[@Cragofitness45]

So talking humidity if you tune a bike at 15% humidity and then do a run at lets say 50% same mapping how Hp would you lose?

That depends on the bike. A normally aspirated bike would loose 5-7hp. A supercharged kawasaki could loose closer to 20..

[@cutdepiefails6596]

Isn't all of these dyno tuning pointless when you don't mimick the ram air?

[@BrockDavidson]

No, since it's not economically feasible to properly mimic ram air on the dyno (it would take a dyno mounted in a wind tunnel). The maps we produce on the dyno are just that... dyno maps. We then tweak them at the race track to produce our 'Track Maps' here is more info: blog.brocksperformance.com/faq/how-can-brocks-get-mapping-so-close/

[@cutdepiefails6596]

That second part was what I was expecting given the quality of knowledge you have. But on the dyno, the airbox has a max mass of air, you have a fan for the radiators, why not have another pointing to the intake that is connected to the dyno to increase air velocity as the speed goes? Doesn't sound either expensive or particularly difficult to get/make.

[@BrockDavidson]

We can shove a leaf blower at the inlets also - and this will usually improve peak performance. The problem is wind speed vs. rpm. It does us no good to tune a bike with a 200 MPH wind speed (or whatever it is) since we have no idea if the bike will ever reach that speed (or develop this amount of airbox pressure). It makes even less sense to attempt to tune at lower speeds/throttle openings this way.

[@cutdepiefails6596]

Brock Davidson the airbox caps at a fixed volume, there is 0 need to have it at 200 mph. Whatever wind speed maxes the airbox capacity is the only wind speed you will need. Do you make air fuel ratio richer on top revs instead? never really got how people only dyno tune cars and especially bikes w/o the ram air simulator.

[@will160176]

@Brock, If you have time can you tell me why when I used flash tune to just simply derestrict my 17 gsxr 1000, it felt down on power. I took it to a dyno and it was running rich and I mean reaching down in the 10 around 7k... 136.7hp at 12.8k rpm peak. Terrible... Switched it back to stock flash and it still feels like a slug. Bike only has 3k miles. No aftermarket performance parts. just derestricting from stock.

@@will160176 The secondary injector percentage can dump huge amounts of fuel into your engine with a very small adjustment.

Their stock image of Secondary Injector % is identical to my original image. So what I did is took their stock image and modified the ETV base maps for each gear in mode A to stay Open at 92.6% and 100% by extending those cells down (kind of how you shown the EU file was stock). It sure feels smooth but I would say it just doesn't feel as good as the first day I pulled that bike off the lot. Around the time I lost power the PAIR valve was rattling in neutral (one at the headers), which simultaneously was around the time they put the Yoshimura slip on, on for me since it was free Suzuki promotional. They adjusted the PAIR cables so that the rattle went away (said it was loose) but bike still felt down on power. So I believe, but cant be for sure, its maybe some restriction in the exhaust, because the few weeks after I first flashed to Unrestricted, the bike felt like an animal and couldn't keep the front wheel down.
