Tweaking PC3 for Increased Horsepower

[@nekopatterson8868]

Great video. I have a power Commander on my 06 Yamaha R1. And I was not Shure how it worked. You did a great job explaining how to set it up.

[@TheChemistDIY]

Hey Neko, thanks for stopping in and posting a comment. Ya its one thing to install a PC but another to tweak it for increased horsepower. I only wish there were more videos on KZbin going more in depth, i guess its left up to me to do so. Onec i get my laptop up and running i plan on doing some live tuning and getting some footage on the net for others to follow.

[@icandsc]

i have a PCIII on my 06 Hornet 919, and I can enter program mode and adjust the levels without starting the bike. I followed the directions on dynojet's website, and the reason it shut off at 02:50 is because you didn't hold all 3 buttons down before turning the key. hold them down while the bike is off, turn the key, and let go. then click whichever range you want to adjust. hold the button down to go one way, click it repeatedly to go the other. when you have your desired setting, watch until the light cycles and drops to the bottom. then turn the key off, and if you want to adjust another range, hold all 3 buttons down and repeat.

After watching your video it helped me make my power commander 3 so responsive. I got power out of my bike that I did not even know was there. Thanks for the video.

Fyi, here's the video to permanently resolve this issue. I made this just a few months back after having to go in there for a second time. This is a known issue with almost all STVA actuators on Suzuki's. kzbin.info/www/bejne/nYOYoZaantyNb5o

hi James, the PCIII version before usb goes into program mode with the bike off. the usb version you have ideed requires your machine to start. cheers!

Finally someone who has the answer. I was wondering myself why this was so but couldn't find any info why some were able and some weren't. Where did you locate this info if you dont mind me asking?

Is there a reason why you need to pull the clutch and zip-tie it? Can't you just put the bike in neutral and then you only need two hands?

No, a lot of bikes have a safety that won’t allow the bike to start unless the clutch is pulled in.

Hi James ,I have Honda vtx 1800c power commander 3 .i bought it use, had install by motorcycle shop and dynos . my problem my bike is running rich. need to bring it down .please help me

[@TheChemistDIY]

Tomas, let me try and understand what you are saying you bought a used PCIII and had it dynoed and now your bike is running rich?!?!?!? Dont understand how that can be if done professionally. How are you indicating that its running rich? (Symptoms) Putting the bike on a dyno is the only sure fire way to tune your bike optimally with PCIII. Everything else is pure guesstimation reallly. Are you sure you have the correct map loaded for your bike & mods? Exhaust/air filter.. If it were me. I would load the zero map to diagnose if the PClll is faulty. Loading the zero map would be like if the PC wasnt there, returning the bike to stock so to speak with the PC still connected. The bike should run normally, if it doesnt then disconnect the PC and connect everything normally.. bike should run fine indicating a faulty PCIII. You can also try dropping all the levels (Low,Med,High) using the indicator green lights and see if your rich condition goes away. Then raise them up till you get to the rich condition and then back it down just below it. Of course this requires a lot of test riding to find the sweet spot of each of the 3 levels but remember this is just the throttle position increased or decreased by like 2% per green bar.

[@yarekczujak]

Without properly dynoing the bike you are just asking for trouble mate... How do you know whats A/F ratio? Also adding fuel doesnt really give you power. its the right AF mix that does...

[@evanwalsh8808]

When you add aftermarket full exhaust/drop in filters you're increasing air flow, thus, increasing the amount of air present in the engine. Under those conditions, you will run into lean AF mixtures. So in order to balance that, you will need to add a bit more fueling while under load. In any case, checking spark plugs is a very good indicator in how well your mixture is and you can judge it off of that... Mate.

[@KAOSshortyrip]

Check.....mate🤣​@@evanwalsh8808

[@Spyder_tsi]

If you load the correct map it should add the fuel it needs you shoulndt have to add even more fuel. All your doinh at that point is just washing the cylinders as the cookie cutter tunes usually run a little fat to begin with to be safe. ​@evanwalsh8808

[@ricksmith4399]

What! You may want to do a little research on how to tune your bike properly.this is not the way and i would advise against it

[@PwndersWoW]

Such an amazing video!! What would be to recommend of + and - fuel to get stock fuel mileage? I got a z750 that uses too much fuel imo. I dont need it to be suuuuper fast tbf😂

[@TheChemistDIY]

Well to be honest, if your not seeing any advers readings from your spark plugs then your bike is running as it should. Remember, black plugs means to rich and white plugs means to lean.... the sweet spot is the brown eye..Ooops... ment Brown color.. tehe. I added my PCIII because the bike was running really rich and fouling my plugs.. I would get back from a ride and stink like exhaust, not to mention I could smell the extra fuel being spent during my ride. I added the PCIII and switched to copper plugs and that fixed everything... copper burns hotter. But if you feel you need to tweak, then you may just want to place all levels at the ZERO mark, This is DJ version of stock a stock setting.. But again, read your plugs.. that will tell you what direction you need to go.

[@PwndersWoW]

@@TheChemistDIY 😂😂😂😂loved the brown eye part. Yeah going to my plugs is a lill hard on my bike, but previous plugs have been black soothy dry. I did however make Low to 0, medium to +1 and high was already at +1. So I will try the setting and see, and also asked dynojet to provide me with possible best tune on their website by giving them info about my bike if not😁 I just want it smoother and use stock fuel or a lill lower, and dont need more hp gain really😂 Thanks again for the video.

Hi, really interesting videos. I've followed your entire powercommander installation. I just bought a gsxr 1000 k7 and what I know is already mapped but i Will compare the map that is in now with the map that the powercommander has on their website. but if I'm going to change the buttom mode, can i see how they were adjusted earlier? Before i do a new adjustment ?

[@TheChemistDIY]

Nicke Enlund Mazanik, all good questions. The map that came with the bike you can always save to your home PC and have a back up copy. Just connect the PC3 to your PC and hit retrieve map, it will display the map settings (fuel trims) throughput the RPM range. From there click save map and store it on your Pc. From here you can either open up and 2nd power commander app and compair the downloaded to the one on the PC3 or just take a screen shot and Paste it into a word doc like i did in the video. If you have the previous owners number i would give him a call and see if the map was created by a dyno certified tech.. if it was you dont want to mess with it.. that map would be tuned specifically for optimal performance of your bike.. cost for a dyon tunned map is like $300.

Great video James. I have the same bike as you. Mods K&N and Tsukigi slip on. No PCIII installed yet. It dynoed at 125hp and 55ftlb torque. Interesting thing was at 3-4k rpm range it was running lean, but after that it ran on the rich side. Like you said, the only way to see the true AFR is on the dyno. So, basically I have a flat spot off idle and then the power kicks in with stock ECU. Just waiting on the PCIII to arrive and then back to the Dyno to verify AFR correction.

I got a K7 1000. I never adjusted the PC. I noticed that my bike runs rich, to the point where I smell like gas when I get off my bike sometimes. I need help adjusting my levels.

[@TheChemistDIY]

Using the instructions in the video check and see what levels the PC are at.. all baseline levels (middle point) should bring down the richness and foulingof the plugs. From there you can test ride and increase the gains till you hit that sweet spot. Also you may want to consider running a hotter plug. This made a huge difference in my fouling and it's very rare now that I get any black plugs. I'm running NGK coppers now. Speaking of exhaust smell, my old engine with 98k miles on it.. use to tell me when it was time for an oil change.. i change my oil at every 3000 miles and as soon as I hit about 3k miles the bike would start producing the heavy exhaust smell so much that my clothes and body held the odor well after any ride. I actually liked the engine this way cuz I would never forget to do my oil changes at the proper mileage.. if you have a high milage bike this same thing may be occuring.. but at any rate you should be changing out the oil every 3k miles.. Let menk now how it works out..

[@TheChemistDIY]

@@Xtreme_Mudding_ATV Got it... So the 3 buttons are only going to make small adjusment variations based off the map stored on the PCIII (Its a program within the map). You cant really program the map with these button because you dont know what those incraments are and exactly where in the RPM ranges or throttle twist that they take place... At best your just guessing what feels more powerfull... Hence why you have the PCIII App.. With the App you will be able type those numbers into the cell table manually.... and to do this corretly it needs to be done live while the bike is running. I never got around to making the video that shows what each press of thses buttons did or added I should say to increased HP. Thats what we really need to know. Now when I made the adjustments you see in the video, I was able to get rid of my rich condition with the settings you saw but this was only after trial and error. What you didnt see was the "over time" part of me taking the bike out for test rides for a few weeks, pulling plugs and checking them and so forth... Thats movie magic as they say.. Some want to just turn these buttons up to max... ya did that to... no bueno, dont do it... Flood city and you end up smelling like gas and exhaust when you get off your bike.. not to mention the bad headach that comes with sucking in these fumes. Now if your looking for increased ponies and dont want to pay a dyno tunner. I suggest you hop on the forums and ask to purchase a tunned map from someone.

How do you know when your getting too much or too little fuel?

The color of your spark plugs will tell you everything you need to know (white, black or wet black oily). Also there is a different distinct odor from the exhaust between each ( to rich or to lean) .. While not always present there may also be present white or black smoke when you rev the bike up. Once you have these tell tale signs committed to memory you can pretty much diagnose any fuel/spark related issue.

Hey Kevin, what's the condition of your PC3 usb. I only ask this because some people put them in the engine bay rather then the trunk of the rear seat. The engine bay gets really hot and is exposed to the elements causing warping of the outer shell plastic and button contact pads. My suggestion is if it's not going into program mode, crack the unit open and inspect the button contact pads and surface of where they touch on the circuit board to insure there good. Also while you're in there take some electrica lcontact Cleaner or 90% alcohol and with a Q-tip give both a little rub down cleaning.. I know it sounds impossible but they may just need a little cleaning to make a good connection when pressed.

Does this adjustment affect all throttle inputs for the given range or is it only effective at wot?

[@TheChemistDIY]

Great question, to tell you the truth the only way to know for sure it to crack open the power commander software and take a peek to see what has changed when you increase or decrease full during live testing, something I'm planning on doing this weekend if time permits. I'll be sure to make a video on that as well so stay tuned. I've been wondering myself where the cut off point is in the throttle position as well. If you do the math and divide 0-100 or 100 (WOT) by 3 (number of buttons) the cut off points in the throttle position would be at 33/66/100, of course this is not very accurate nor does it tell you the RMP range side of things. Sorry I don't have a better answer for you but you are going to get a video out if shortly..

[@Loopyengineeringco]

The low/mid/high refers to RPM ranges, not throttle input (says this in the manual). Not sure how the ranges are blended, but I imagine it's a smooth interpolation over 2 or 3k rpm as opposed to a hard switch

@@TheChemistDIY I didn't found a .djm file map for PCIII, only .pvm extension and I can't found one to match. can you help me. I'm a newby on this PowerCommander thing. Thanks

[@CP-kb1du]

The only use a power commander 3 has is to enable a quick shifter other than this maps are useless and redundant . Once connected the bike will run horrible way too complicated to use.

[@TheChemistDIY]

Not at all brother, before the install my bike was running extremely rich fouling up my plugs. After the install of the PC3 and the loading of the map with my mods the bike totally leaned out. With a few tweaks that are demonstrated in one of my other videos i got some major performance gains..my bike runs like a champ and has some major pull especially on WOT. The first owner said the same thing but he couldnt have been more wrong.Never go off what you hear, always test for yourself.

[@davem7492]

How do you get back to the program settings if you adjust with the three buttons, and then want to go back to your installed program?

[@TheChemistDIY]

Good question since this is not outlined in PC website or instructions. My best guess would be to document each of the 3 settings before making your tweaks or just reflashing the PC3 altogether to return to the unit to stock programming.

[@stavencapp]

To go back to the map setting you have loaded you would basically set the low mid and high to the 0 (middle) setting. All the buttons are doing is increasing or decreasing the fuel for whatever map you already have loaded at the time

when i hit very high RPMs in 2nd or 3rd i get a nose dive like my bike red lines and then f1 light comes on, i assume its my power commander, what do you recommend I adjust it to?

[@TheChemistDIY]

What up Tylor, remove the PCIII and plug the harness injector connections as normal.. take for a ride and see if it does the same.. if the bike runs fine.. then your PCIII is your issue. Before call it bad I would inspect all connectors and loads a fresh map and reinstall to see if it works...

Yes is possible

[@frederickbylsma4101]

can you change the button adjustments on a laptop as well? reset them all back to "0"? my mid range button seems to be jammed so i cant see what the adjustments are

[@TheChemistDIY]

From my understanding programming the buttons themselves (level of control) with the PCIII software is not possible. Additionally ive never taken the time to see just how much each press of a button increases the fuel amount in the verious RPM range, that would be a good test to perform to. see the live data roll across the screen.

[@toddgirard391]

Thx for the video awesome

[@jeremesebero4549]

Can this mess your bike up?

[@TheChemistDIY]

Jereme Sebero good question, no not at all but adding to much fuel at the wrong points may cause you some problems. For example from a take off you reallly dont want to be dumping in a shit-ton of fuel, this would cause the injectors to flood the cylinders with large amouts of gas its not ready for thus stalling or bogging the bike. If that occurs you would need to just back it down a bit. Instead you would want to add more fuel in the prime spots of the rpm range when the bike is in motion say like in 2nd gear around 5k rpms to give you that quick boost. Hope that answers your question.

[@dzl8596]

Run it too rich and the excess fuel can get into your oil.

[@Raje617]

I just bought a new to me bike and I'm running a little too rich. What would be a good suggestion to back down some? Maybe one bar across the board to start? It doesn't bog at all and has great power but a tad of black smoke on start up. Nothing bad, just a touch more than I'd like. Thank you in advance. Great info here! 😊

[@vincentmeredith2561]

This is nice but if you go into the program on the laptop you can fine tune it by modifying the map i played with mine in the map on the computer didnt do the best job cause now i run a little rich so im just gonna go into it this weekend and bring the map back to what dynojet uploaded

[@TheChemistDIY]

Tru But I find map tweaking is all subjective. Where the truth lies is on the dyno where you can see the real numbers. What I haven't done, and hope to get around to is putting the bike on the computer with a fresh stock map from dyno jet and pushing these buttons to see what exactly does Increase when messing with these buttons. This should give you a good idea after review of how you can tweak your map for better gains.

[@MrKickflip74]

I would like to get better low-mid range on the bike. I want a safe tune. Can you send me a formula you think that would help the rpms low-mid thanks alot man

2 bars up from the middle point is what i run my low and mid at.. lots of get up and go!

[@2WheelRider_Catch-up]

Thanks Fam!! Got My 2004 Sv1000s to give me a little more Throttle Response before I take her to get Flash Tuned 💯💪🏽🫡

[@JamieMac203]

This or fuel pak fp3 ?

[@TheChemistDIY]

Man, that's a toss up bro.. hard to say.. FP3 by V&H has a lot of cool features and seems to makes programming look really easy, but looks can be deceiving. Pc3 on the other hand is just download a map and toss it in ..thats it.. you can tweak PC but not very much without a dyno.. I've never had the luxury of experiencing how well FP3 programs and controls throttle response because all I've owned is cable controlled motorcycle.. I'm not one to speak about something I dont know about so I dont want to give you bad information, but what I can say is do your research.. the forums are you best friend, and know all the pro & cons. There are only a hand full of fuel management system to chose from.. know them all like the back or your hand and then pull the buy trigger.

[@JamieMac203]

Reason im asking is because i traded a pickup with low miles that i got for a sweet deal for an 07 harley nightster . Has vance and hines exhaust & high flow intake . Now in my head thats all that this bike has upgraded to it & the previous owner thats all he knew as well. So yesterday im in my garage and i say let me take off the seat and see whats under there & boom there is already a power commander 3 usb. I knew this bike had some serious balls but i did not think it was tuned. Funny part of the story is i have a fuel pak fp3 arriving in the mail today & the day before it arrives i find out my bike already has a tuner on it. Did tons and tons of research like u said and decided to go with the fuel pak fp3 but now im at a toss up if i should leave the power Commander 3 on there or should i swap it out for the fp3 .. my thoughts are what if the previous owner or the guy before him did a sick tune on this bike and its reaching its peak performance? Will the fuel pak per say downgrade it ? AHHHH IDK WHAT TO DO HAHA

[@TheChemistDIY]

@@JamieMac203 lmao.. that is a dilemma brother.. ok ok.. so heres what I would do.. take a trip over to dynojets website.. register and down load the map for your bike with what ever goodies that have been added.. open that map up on your computer and take a snapshot of the screen.. now go back to the bike and plug in your usb cable and download and open that map.. and compair the two.. if you see the numbers way off from the orginal map from dynojet then you know that the previous owner(s) have most likely had the bike dyno tuned and sticking with a dyno tuned map would be the best performance you can get rather then tweaking presets. If it is tuned, The name of the map may also be different by the tuner so that would also be a good indicator that the bike has been tuned.. if it were me tuning I would have given the custom map a date and type of tune.. but that's just me.. But just for shits n giggles I would still hook up the V&H to see which one I like better.. I mean you chose it over PC3 for a reason..

[@JamieMac203]

james moreno haha good idea man thanks for your help

[@guitarskooter]

Dont know if you still read these, but will this just tweak on top of your PC map? Or does it reset the map to default and use these values instead?

[@TheChemistDIY]

I read and respond to all my video comments brother, so don't hesitate to ask your questions. Think of the PCIII as a translator. It takes the signals from the ECM and TPS in, compares it to its own MAP and adds the extra juice to give you better or increased performance on its way out to the injectors.

[@masterofbrewtality]

Can you not just start the bike in neutral to program it?

[@TheChemistDIY]

Yes you can and thats what was shown in the video. Starting the bike in gear with a zip tie holding the clutch in is highly dangerous.

[@masterofbrewtality]

james moreno ah okay I can start my bike in neutral without holding the clutch

[@TheChemistDIY]

@@masterofbrewtality if you have done the clutch bypass mod then yes. But remember you have to be holding down the 3 buttons at the same time you start the bike. Thats why i say to zip tie the clutch up so you can turn the key while holding down the 3 buttons. If not then you'll need a 2nd person to help you out by holding the clutch down.

[@darrencoulis7194]

I have a pc3 and a 2007. Suzuki m109r with gutted stock pipes and aftermarket air filters what map would I use for gutted stock pipes??

[@darrencoulis7194]

Anyone??

[@TheChemistDIY]

This is a hard question to answer simply because back pressure is unknown. The job of the PC3 is to give you the best air to fuel mix ratio for performance and with nothing to compare it to thats hard to do. Realistically the only way to get that is to put the bike on a dyno and see where it works. For now my suggestion would be to try using the most free flowing exhaust map and then tweaking it with using either the 3 buttons on the PCIII or really diving deeper and tweaking it using a computer. Back pressure is mostly needed for lower end rather then higher speeds and youll notice this before your tweaks (slower take off or launch).. once u start tweeking the bike should get faster in its launch. . Hope that helps.

[@dodge4210]

Just turn on the ignition while holding the 3 buttons. No need to start the bike.

[@TheChemistDIY]

No sir, power cuts off after 3-4 seconds. It wont-work that way. Not sure if it's TRUE or not but what I've been told by a viewer is that there are 2 versions of the Power Commander. One that keeps power active just with the Ignition or accessory turned on and another that requires you to have the bike running. I apparently have the version that requires the bike to run.

[@dodge4210]

That's strange man. I build bikes and never heard of such. Not to say I know everything just never heard of that. Every bike I've encountered was able to use the ignition in the on position with the engine off. I have some hunting to do now. Lol

[@westieBrucedavidson]

I was told after tweaking the pc3 it takes 20 minutes riding to make the unit accept changes Is this correct in your opinion mate?

[@TheChemistDIY]

I've never heard of this myself Bruce, but it maybe true if we dissect the steps. The stock ECM sends the pulse to the injectors which is now being intercepted by the PC3 via the injector connectors and TPS signal. The PC3 then gathers that information and runs it through the new dynojet map and re-translates it for better performance. If the PC3 has a learning function then it would need to gather a certain amount of data, 20 minutes of ride time as stated by your mechanic to make a comparison of what would good for optimal performance of you riding machine. So this could be very well true.. I for one have never delved that deep into how the PC3 begins to translate the data... but I can see your mechanics logic in your mechanics statement.

Hello Steve, thanks for stopping in and commenting. We all have a learning speed at which we comprehend and absorb information and for some that speed may be slower and needs more guidance. Most of my DIY instructional information is geared towards the beginner or why else would a person be researching and reviewing something they already know. I see that you just recently joined the KZbin community, lets hope that when you start producing video content you keep that in mind when generating content for your fellow KZbinrs looking for your guidance and trusting in your knowledge. It's one thing to sit behind a computer screen, watching and critiquing those that do. It's an entirely different experience to be the educator that produces that content having to manage the work of not only the instructor but the production crew as well. Hope this information gave you some insight into why things are the way they are on my channel, and I hope you stick around and learn with us.
