Kawasaki Ninja ZX-10R (2019) ECU Flashing with Mad Scientist Don Guhl

If you had a full day to ask Guhl Motors’ owner (aka ‘Mad Scientist’ and self-described ‘white hat hacker’, / guhlmotors ) Don Guhl, questions about ECU flashing, what would you ask? Well, Brock knows what HE would ask, and it leads to some very detailed explanations on ECU flashing as well as few uncomfortable moments. Brock even grills the ECU wizard for answers to questions many of you don’t know to ask -yet-. Just keep watching our channel ;)
In this episode, Brock’s discussions with Don uses our buddy Mike’s 2019 ZX-10R as the example, but the theory discussed also relates to most modern-day sportbikes. All Kawasaki sportbike owners yearning to extract race-worthy performance out of their machines will find this episode particularly interesting. How much power does Kawasaki’s newly revised ZX-10R power plant have the ability to produce using ONLY electrical modifications? We answer this question while demonstrating the steps along the way, and we don’t need to tell you how much Brock enjoys presenting highly technical information in a way that is easily understandable. Now Don on the other hand… well, we think you will enjoy how they team up!

If you are switching tuning software, it is best to flash the ECU back to stock and start fresh. Otherwise it is possible to render your ECU useless.

My recent discovery of Brock’s KZbin has been just a revelation. From seeing Brock’s exhaust on bikes and taking interest to the point of watching a video such as this from start to finish! My happy dream is very small…a 2021 Yamaha mt-09sp which has a cp3 triple motor. I’d like Brock to make me a special under bike exhaust that terminates right behind the right peg of the bike. I’ve seen Moore get a crazy tune on a 2020 I believe? Brock just explains the process a whole lot more…which really instills confidence in me. Or the common term….”just take my money plzzzzz!!!”

[@rodneyberry531]

The japanese manufacturers have been at this for over a decade. My Gixxer 2004 1000 is before drive by wire. It had the secondary throttle valves in the Keihins. The way they have done it on mine was to lean the fuel from over 9000rpm or so, particularly on full throttle. I always wondered why in laid over, and you could hear the valvetrain was just spinning, not driving and accelerating ie went noisy/rattly. They leaned it to the tune of 20-25%....can't imagine what the air/fuel ratio was.....but I must say they are pretty tolerant of a wide range of values ie combustion technology is amazing. The secondary throttle valves had some pretty weird mapping std, but at least they were open from that rpm up (at all throttle positions no less!). There are also gains to be made with the ignition timing, partiularly in the driveability range that he talks about in his other videos.

[@rasheedvitalis]

That was great information. They totally explained the science in regards to ECU flashing. If your going to get your bike flashed, might as well get it done right.

[@vincecastillo6752]

Good day I'm glad I came across this video. I notice in your video the bike didn't start back up. What was the issue?..I believe I have the same problem with my bike , I'm getting fuel but no spark.

We must cycle the key on and off 3 times after the ECU is flashed, then they start right up.

[@JesseK410]

Thats wild. Theres gotta be someone else doing it tho..im sure he isn’t the only one who can force it to read his map vs the factory’s noise restriction maps but im sure its complicated and not just anyone can do it unless there a programmer aswell haha good stuff Brock really interesting how they have the ability to do that, funny how they would even keep the exhaust servo motor basically closed

[@shanevermij4780]

Don is a genius, I once met a guy that does this to truck and car ECU's, he could check barcode numbers on an ECU then rewrite it so there where sunstantial power gains

[@MoleDoesStuff]

So is the throttle restriction from factory in the ECU for protecting the motor or is there another reason for the factory to restrict that way? Are there any special considerations one has to take when derestricting their bike? My bike has carbs and just dumb computers being from 1983 so this beep boop fancy stuff is all new to me!

[@BrockDavidson]

The throttle restriction is primarily for reduced emissions and noise abatement...mostly to appease California. The same engines are derestricted all of the world with no reduction in lifespan.

[@jonazevedo28]

At the top you are running rich and you are bout to adjust that air fuel. Are your fan setup to simulate the ram air effect which would add more air at speed. Countering that rich condition at the top?

[@BrockDavidson]

We don't have the means to truly mimic ram air effect in a static application - we would need a dyno in a wind tunnel. Fan's faking a constant 200+ mph at any/all rpm's and wheel speeds are nothing more than a morale boost to the dyno operator (and bike owner). If you notice our dyno room, all attempts are made NOT to force air into the inlets. We use data gathering at the race track to truly track ram air performance vs. ecu compensation - you would be surprised, Generally speaking: most Suzuki ECU's overcompensate with too much fuel, most kaws undercompensate - the BMW's do the best at getting it right. We will elaborate more once we get to the track.

[@Nikdik]

Was wondering what kind/brand radiator fluid you like to run in your motorcycles? Or recommend for street riding. Thanks.

[@BrockDavidson]

Great Question! For racing, we are mandated to use a non-glycol based coolant, because glycol-based coolants are toxic and difficult to clean up after a spill/crash. Does that make it better for street bikes?...not really, in fact it can cause great grief for your bike is ever subjected to freezing temps. These water-based coolants can do an excellent job of keeping your ride cool on a hot day, but if your bike is subjected to freezing temps, the water can freeze. What's the big deal? Your bike has 'freeze plugs' that will pop out in case the coolant ever freezes - once out, if you start your bike - as soon as it warms up, the frozen mixture will dilute your oil and possibly cause catastrophic engine damage. We learned this the hard way after trailering one of our race bikes from our heated facility in Ohio, to a race during freezing temps - there is no way to tell if you have this problem unless you view your oil and it's 'milky-looking' from mixing with water. We rode the bike to tech, made a run and had completely wiped out all of the crank and rod bearings by the end of the 1st run. It was an expensive mistake. We use standard antifreeze (usually the 50/50 premix) or we use #evanswaterbased coolant in our streetbikes here @brocksperf - or MoCool in our race bikes: brocksperformance.com/motul-mo-cool-radiator-additive-16-9oz/

[@nak_attack]

Does tuning in Full Power mode, Medium power mode and Low Power mode matter on 19-20 zx10? I have a tune in C85 via power commander 5, but my bike has not liked e85 in general the way it runs. I know c85 can only be run with c85 and X85 is okay to run with pump e85, but It’s been a hit or miss on pump in the streets. The dyno was amazing on c85 , but once I took it out to race (higher altitude) it did not even want to cruise. I definitely could’ve tuned on ECU alone , but I’m curious if the bike would adapt or feel better depending on the modes, tuning on just the ecu only or if the modes it’s just neutral all across and I can potentially run different fuels while tuning on ecu

[@BrockDavidson]

No. Different modes are controlled primarily by the electronic throttle valve. AFR is AFR regardless of the mode you're in. What you just described is exactly why we do not offer e85 or c85 tunes at Brock's performance. They seem to work well for cars, but motorcycles are not smart enough to take full advantage... Unless you are at wide open throttle, where driveability does not matter.

[@nak_attack]

@@BrockDavidson yea for more power/race. Do you know if adjusting timing is necessary for any e85/c85 tunes? I’m just trying to make mine work where I see everyone else on c85 near me is making amazing performance for straight line power.

What makes them have such a big power difference to like a Beemer 4 cylinder? The S1k seems to be at 190 without much hustle wrt tuning.

[@BrockDavidson]

That's why the S1000RR has been the bike to beat, but even they are confronted with strict noise and emissions regulations that hamper the performance of their newest models.

[@bobouistic]

@@BrockDavidson I saw that with the retarded dead spot, but is it about the tune, the cams, the pistons. As in what is making S1000RR and the Ducatti hit 198+Hp with a little tuning while the likes of Kawasaki are at 185ish after tuning? 15Hp is a big gain I believe.

[@BrockDavidson]

The Japanese only understand one thing....follow the rules thoroughly, completely and with integrity. And you are correct 15 hp is a giant gain.

Hey Brock how are you? I have an 04 zx10r I took my bike to a shop and had a 08 intake cam installed along with a mail in ecu flash I'm running a 17 tooth sprocket on front and a 40 on the back. Before I had the work done I was running 17 and 39 and my bike had plenty of torque and power. Had no problems raising the front tire in 1st 2nd 3rd and sometimes 4th. Now it wont raise the front tire at all it seems I have lost all torque and alot of power on low and top end any suggestions on what I can do or what the problem is? Some else had the same setup and said that I would have to re degree my cam to 105...

Best advice would be to find an independent dyno to test your engine.

This video is pure automotive porn. If the information contained in it could be turned in to a wallpaper, I would wallpaper entire house with it. Also from the outside. It's time for the bed now, so I am sure my brain is getting re-flashed overnight. Could not have come across any better thing to watch, that's for sure.

[@shanevermij4780]

At a point will the factory "de-engineer the bikes" so that they cannot make the power that both you and Don are doing to these ECU's?

[@BrockDavidson]

If a company is in the "fast bike" business, making slow bikes that are difficult to cure is not good for business.

[@danny996]

How come data logging from the ecu itself isnt possible and you are using a power commander?

[@BrockDavidson]

Data is available from the ECU (OBD2) and we do use quite a bit of it in our testing. We use the PCV to tune fuel in conjunction with the tuning link function on the Dynojet model 250I, as we find it makes a far more precise map than fuel tuning through the ECU. The PCV is also friendlier to tune at the track, especially if wifi is not available or weak. For those who do not like PCV's, we have flashes available with no PCV required, but they are not able to be user-tuned: brocksperformance.com/brockflash-ecu-stage-1-f-with-fuel-tune-for-full-system-zx-10r-2019-must-send-us-your-ecu/

I just got the younger brother model of this bike same year a week ago... the zx-6r, same color storm gray. Wish I could afford the big bro version.. some day. My 2015 636 got stolen... Love my bike so far though. Still breaking her in, only 250 miles on it. So hard not to rip the throttle lol.. I'm trying to break her in properly so she will last me... I got a whole christmas list of mods and plans for her lol.

[@Dominic650s]

I just purchased an 06 zx14 with flies removed and PC5 installed, the throttle is very choppy at startup until it warms up. Can I just put it back to stock or it requires a tuning.

if the flies are removed, it will need to be tuned.

[@kirtfeagins2107]

Brock do you know if the 2019 636 does the same thing with throttle position when it reaches high rpm?? I have a 2019 636 and it feels like it falls off way before the rev limit.

[@BrockDavidson]

@Kirt - what you are feeling could be a number of issues (intake flow/exhaust flow etc.) To answer your question - yes, the ECU is causing power issues by limiting the opening of the secondary throttle plates. They are not fully open until about 9500 RPM and they close down to 60% at revs just before the peak rpm limiter. Give Guhl a call, they should be able to help you.

[@kirtfeagins2107]

@@BrockDavidson Okay thanks 👌

[@nextgen2062]

I have the same 2019 ZX10 same color as well. My concern is does an ECU flash take away from the bikes longevity?

[@BrockDavidson]

Great question. In a nutshell, the flash matches other non-restricted international models with slight enhancements. If the operator stays at a reasonable rpm for a reasonable time, there is no reason to expect a lack of longivity.

@@BrockDavidson thanks, makes sense. Last question..would you trust mail in ecu flash? No dyno.

[@randyschmidt19]

looking at the TPS on the dyno, even after modifying the table, the throttle seems to open slow.

[@BrockDavidson]

It does, but opening the throttle plates sooner doesn't necessarily mean the bike has that ability to ingest more air - but it does mean that whacking the gas wide open at lower RPM in higher gears results in a miss/sputter and even a stall if the rider does not intervene. We will fine-tune the opening rate to match the additional intake and exhaust mods as needed.

[@randyschmidt19]

thanks for the reply. can"t wait for the next video

[@GuhlMotors12345]

This is the beauty of these throttle-by-wire systems! The manufacturers can size the throttle bodies for additional power without worrying about affecting part throttle performance and low/mid range power. With this style system we can program the throttles to open enough to give us best power, but not so much that it hurts performance. Testing these settings are now a standard part of tuning these new "high tech" bikes. 1 to 1 throttle opening on this bike would be a disaster!!! :-)
