Brock Davidson hey I convinced my dad to buy the gsxs 1000f last year and I was wondering if that bike would have the same throttle plate issue because to me it seems to have a very odd power surge Also I was wondering if you had anything for that model because it has the 08 gsxr 1k motor in it
Thank you for posting the video, Brock. It is very informative, and with things caught on camera we now have solid evidence along with empirical data to support the reality of the restrictions imposed on these newer bikes. I own a 2009 GSX-R1000. Do you happen to know how much restriction there is on this bike? (e.g., at what point throttle blades close during wide open throttle, ignition timing retardation, etc.) I think the 2009 - 2016 Gixxer liter bikes are the same, so if you have any information you can share on the restrictions on them that would be great.
Wow, that was a very fast response! Thank you Brock! However, I am confused by what you mean when you said no restrictions beyond the standard exhaust. I have spoken to two dyno tuners who own their respective service shops. One told me that the bike's throttle blades are 95% open at the upper rev range, and the other told me 94%. Consistent information this is, but what can you say? I am thinking of flashing my ECU, but I thought I should seek your wisdom as you are very experienced in Suzukis.
16:05 I can totally feel that restriction down low in my 17 GSXR 1000R, it doesnt come alive until 7k and dies at about 11k. Very excited about tuning it now. Excellent video man
I have to say since watching your videos I am learning something new each video. I have minimized my TV watching and now educate myself on Brock's videos. Not a sport bike rider but I love the mechanics having spent 41 years plus working around steam turbines, gas turbines and generators.
This video is exactly why I buy Brock's exhaust on all my bikes. He willing to share information where other companies are so hush, hush. Although I ride a 16 BMW S1Krr now I owned 4 Gixxer 1k's and I'm glad to see Suzuki is back in the game. I will follow this build til the end
Hi Brock I'm watching from the uk and want to say thank you for educating me, I feel as if I should be paying you for all this information and am very grateful , I look up to people like you passing your information down to the next generation of humans not knowing a thing about this area like me, lol so thank you again from all the way from the uk 👍🏽
Great video Brocks team we all love the step by step build project on this this gsxr 1k and the information that your putting out there for all to see a glimpse into the dyno world I'm sure myself and a lot of us out here take all that tuning for granted and just throw all leg over these bikes and go ride
SICK!!!! Cannot wait to see more impressive already i need a bigger garage!! Thanks again your videos are meticulously done and very informative and to see the power gains step by step is awesome keep up the good work sir!
New to your channel. I'm just getting into working on bikes after one retirement lead me into another career. Ive worked on locomotives and tractor trailers, but never a gasoline motor...of any size. Ive got 3 bikes, 92 ZX7 (last year of the Hoover hoses), a 24 anniversary edition ZX10 (tune and dyno by Moore Mafia) and an 06 Busa that just received the full Penta Carbon system and other upgrades. Bought it to take to the track and learn something new...which might take me into a 3rd career or at least a hobby. Hope to see you at a track one day.
Glad to have you! We pride ourselves on giving the home tuner or tech the info. needed to get our same results. Dig deep into our archives for enough info. to be dangerous! ( As well as successful 😉)
Brock way to show your customers what's going on, you are the man ! I just hope it gives BMW a run for the $. I'm waiting on the next busa to share a room with my ZX14R, I love Suzuki products.
Woowwwww All I can say you are the man, I have recently suspected exactly what you have just confirmed. I have a 2014 BMW HP4, 11 GSXR 750, got rid of my great 05 GSXR1000 (much regret) among my heard (02 GSXR 1000, (2) 06 Ducati sport Classic 1000's and a project 2000 TL1000R), but I too have always been a Suzuki man. You just solidified me getting a new 2017 GSXR 1000 RR The King is back ...
This is the bike I've been waiting for. Can't wait to see what you guys do with it. I would love to have a brocks tuned gsxrR. When I get mine in sending it off to you guys. love the video's. Keep up the good work.
Brock tell me, please: is it just ETV derestriction or fuel was corrected also? What was AFR in comparison to stock after ETV derestriction? Thank you for GREAT videos and knowledge!
Looking forward to seeing this series as it progresses. My question is doesn't flash tune make it possible to tune everything within the ECU the same as you would with a power commander? Wondering why you would have to add on the piggyback ECU controller with the flash tune, or am I thinking about this wrong?
@ 2M That's their claim and we plan to demonstrate both. Currently, Flashtune does not offer active tuning for the 2017 GSX-R1000, so we any ECU tuning would be a course guess compared to what we and do with the power commander. Once active tune becomes available, we will use it also, as well as their PCV map import function into the ECU. We have PILES of info. to come!
Great vid, love messing with this stuff too. Got a power commander and Woolich racing flash on the 15 Zx10r and Yoshi system. Can feel the torque / hard pull now. Not 100% keen on fly by wire.
These videos are awesome, makes me want to buy your Products, you actually know what your talking about.

The most informative video I ever seen regarding the process of tuning a bike. Just one question, does the bike runs lean with the secondaries wide open?, if not, is the ecm and oxigen sensor correcting it? When I pull out the secondaries on a Vstrom 1000 I had to enrich a lot the mixture on top. Thanks !!
7 ปีที่แล้ว +1
You already ansewered my question down below. Keep going Brock !
7 ปีที่แล้ว +1
I have another, QA at mid low rpm its better to have the secondaries a little close for better torque, did you lose torque at mid low rpm? Seems that this is going to be on par with the mighty s1000 or more!
@Sebastian, it is better nowhere (power-wise) by having the blades closed. I have resized a dyno chart to show that it gained @3hp and 3 ft-lbs from 4200RPM - 6500RPM by having them open sooner: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg
But im curious about thr hp made without an airbox. Also curious because i read on a bunch of forum's that ppl do the airbox mod. Either take the lid off or drill holes in the airbox. You don't seem to do that. So is that not a worthwhile mod?
The air box is in place to prevent the engine from drawing air from the low pressure area behind the fairings, it also keeps engine heat away from the inlets...the engineers who designed the bike have a full understanding of it's operation. It does not need poked/drilled/removed etc...
Hi Brock. Wow man, well done on this episode series so far. I share your excitement every step of the way. Do you perhaps know if other 2017 models have similar throttle blade restrictions? Thanks for your honest videos, really appreciated.
@Jayden Valentine - we offer Flash packages with a PCV fuel tune to allow the customer the flexibility to adjust their own fuel mapping, or use our maps, available through our Map Support Program, with a purchase of a Brock's Performance exhaust. Click here for more info: www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=406&zoneid=22
Hi Brock. Not to question what you do, I love watching the tech videos and find it very interesting, but I just have a question myself. I watched what you did, with the Flashed ECU, telling the blades to stay open, thus giving it a higher HP output, but isn't that change you made going to affect the bike running more rich? Should you not also tune something regarding the air intake and the inlet and exhaust valve openings as well? Seeing that more fuel goes into the system, you need more air to ignite it properly. Can this not cause the bikes engine to have pre-mature ware over the long run? I understand Suzuki has to tune it like that, to meet emission requirements etc. Unless this video you made was just to show us what happens when you just tune the throttle blade positions, and your still tinkering with the air/fuel mixture to be spot on, as well as the correct opening of inlet and exhaust valves. Thanks again for your informative videos, I really enjoy watching them.
@EDW 845, thanks!, and good points. Please consider that when we open the inlets, with no additional tuning, the bike gets LEANER at high revs, not richer, as shown in the red line in this dyno chart: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg the rest of your questions will be addressed shortly.
Its strange that it would run leaner, and not richer, but I guess the air flow or o2 sensor picks up that there is more suction or air being displaced through the system, and compensates for that. I will be keeping a close eye out for when your next video appears. I myself, am a Suzuki fan, and switched to S 1000 RR, purely out of frustration due to Suzuki taking to long to develop a bike that can run with the rest of the pack. If this bike does beat the S 1000 RR, I'll consider switching back, but I'm still a bit skeptic, as BMW has set the bar quite high, but hey, I'm open to having my mind blown and proving myself wrong. They have been there before, nothing holding them back, to be on top again.
Brock, loving these videos, so interesting seeing how you tune these bikes. I just have one question in regards to restricting (and tuning for more power) - What (if any) effect does this have on all the stock parts such as the pistons, crank shaft, all other internal parts - Would these parts be more likely to break or wear faster after tuning as such ?
My take on it is this: we are only removing the restrictions the OEM's are FORCED to put in place. They KNOW what is going to happen to these engines after they leave the factory... we are simply allowing the engines to work as if they were not restricted in the first place. And THAT is the key. Don't get greedy - just remove the restrictions and the bike will live a long and happy life.
Brock I have one question for you that I think is very important, why you use power comander when I have Rapid Bike Racing, our bazzaz, I say this because I earth professionls saying that Rapid Bike is a more " complete " better hardware when compare to power comander, is like you can do more on the tune with rapid bike. If you can aswer this question I am going to be very happpy.
Brock Davidson thank you very much, Just another question in my country we only have 95 and 98 octane fuel. do you think we can make more Power Just Puting 98 octane fuel ?
I think that 95 and 98 are just more cleaner that's all, but noted, 89 octane in the US is about the same as 93 or 95 octane in South Africa where I'm from. Not a expert at this, just guessing
Great Videos Brock for sure I have learned alot. I do have an R1 and I do watch 650is's videos and want the best performance for my r1. I do know about the throttle bodies and have not fixed the flash just yet But that will get done ASAP.
Amazing work and explanations. Impressive how injectors are spraying ! Brock, do you know if this throttle restriction from Suzuki is proper to US model or if it is common to other GSXR sold abroad ? I wish we could have a guy like you in France… Maybe Thornbike. Thanks a lot for sharing you experience.
@atirocky, yes the euro versions are restricted as well to meet Euro 5....Ironically, the US versions are more restricted as California rules are even more strict than Euro 5.
@@BrockDavidson , thanks for your answer. I now own a 2020 R model. It has only a slip on exhaust (Akra GP - no street legal, too loud…). In winter, I ride it in B-mode. Very smooth bike, except at 4000rpm in first or second gear where at steady speed, it feels jerky, like on/off power. Before sending on a dyno, do you think it could be solved by an ECU flash ? (TPS or disabling fuel cutting at deceleration or air/fuel ratio or…)
@@BrockDavidson , thanks for your reply. She is all stock. She only eats unleaded 98 ( E5) or E10 (unleaded 95 with 10%ethanol) as it is recommanded by Suzuki. She is smooth like butter under 3500 and over 4500rpm.
@@atiroocky the simple addition of a pcv with a proper map should cure your drivability issues. If you are into high performance riding, a quality flash with fuel tune would do the trick as well as increase your performance.
@Mark Ramoutar - great question! The AFR with the stock ECU at peak power was 11.8-1, the AFR with the flashed ECU was 12.8-1, I would assume that more power could be gained by tuning to an even leaner AFR, but it's something that would need to be adjusted and measured. FYI: Our goal is to install aftermarket components and tune, not tune for stock parts, so we will find out the answer to your question as the project progresses with these aftermarket installations.
Brock Davidson. Awesome! I can't wait to see the results. you have me thinking about ditching my hayabusa and going for a 2017 Suzuki GSXR1000 with all these informative videos.
@Mark Ramoutar, this link shows the AFR change. Note that it's still quite away's off from the 13.2 line: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg
When you do the part upgrades is it possible to do a dyno run on it without MR12 so we can see direct comparisons. Really hard to tell what impact the racefuel is having with dyno videos when people put on a bunch of parts then put in MR12 in at the same time. Sort of hides the gains from parts/tuning on normal fuel.
@Cambell Reynolds Mr12 runs will be at the end of the series, used as our 'gauge or standard' fuel so the 2017 GSX-R1000 can be compared to all previous performance makes/models. Until that time, the standard for this series is 89 Octane Shell, as noted in the description above.
Awesome stuff Brock! Love that you love the details as much as I do, data means everything! Love the “Ass Dyno” for sure, but numbers never lie! My ass though, has lied to me before, and the data shocked me! Again, well done Sir…..
will the changes to the ECU throttle % affect how the other systems function that control the throttle, like launch/wheelie/traction control etc? or are they independent of throttle position?
How does this effect traction control and the ride modes? Although i use neither. And when will this be on market because im very tired of feeling the throttle curve from the factory. I want the throttle to follow my hand
That will be explained, in detail, in upcoming vids. In a nutshell, it depends on the flexibility the person tuning the bike wants to have. Power Commanders make it very easy to make tuning changes - ecu flashes are set and forget.
My bogusomiter kicked in. Of course I could be wrong but, switching back & forth between the two several times it's odvious from the sound that you are not revving as high after your flashed ecu as when the blades start shutting down pre flash. And having the dyno tachometer off lends credence to my suspicion. I hope I'm wrong. I've witnessed too many snake oil pushers, especially in the bike hop up market.
??? The tach is off because moments into warming the bike up on the dyno, it trips fault codes from the discrepancy between front (zero mph) and rear (175 + MPH) wheel speeds.
Brock Davidson also is this restriction the same for the European models as mine (UK) pulled 174 on dyno.. although many people think my model may be American as it had reflectors on from wheel and the indicator lights are permanently on, something which is only standard on American models I'm told
Is there any change that the throttle blades are speed sensitive ? The front wheel is not spinning. Maybe they only open 100% after 100MPH + in a higher gear ? ect.
@James Park No. The ETV mapping is controlled by throttle percentage and engine RPM, per gear and per power mode selection (A-C). For this test, we altered Mode A (gears 0-6) 100% throttle - all RPM's.
@Joe - most dealers stay away from ECU performance mods/flashing. Your 05 Busa really isn't restricted like today's bikes, but the top speed limiter can be removed and the peak RPM bumped. There are many 3rd party ECU flashing softwares available these days to allow you to do it yourself, or contact Guhl Motors or Ryan Schnitz for a mail in flash service.
Yes. But please understand that we are a highly specialized company. Use the product search for your make/model - once an item come up, you can use the checkboxes on the left to narrow down mfg. If you don't see any items in your search, we do not have products available for your bike.
When you are swapping ECU's like that, do you need to code the keys again to the new ECU or can you disable the immobilizer entirely? Also; is de restricting the STAV actuator something which can be done at home without a new fuel map? or would you need to a new fuel map to cater for the throttle blades opening ealier and staying open from 4000rpm onwards? lastly, what tool do you use to flash the OEM ECU's ?
@luke cooper - it depends on the bike. Some we can keep the immobilizer and most we can simply disable it, if required. That depends also, if you mean disable it manually - you can remove the secondary plates. Older bikes might not require much mapping, but almost all newer bikes do. We use MorDefy by Guhl Motors (beta) ftecu, winols and a couple others. Search forums dedicated to your bike to find the one most that owners are most happy about.

@@BrockDavidson Thank you! you're videos are extremely saturated with knowledge and experience. I wish you the best of luck and ill look at your blog. Thanks!
Sounds like a reasonable, easy question...right? But it depends upon many variables, one of which is that the higher you rev the bike- the more it restricts itself. We remove the restrictions and follow these rules: bit.ly/36aRSEt

It's most throttle by wire bikes these days. BMW s1000rr, almost all R1's, almost all ZX-10's, H2's are the ones we are working with.
After you've perfected everything would a consumer be able to send in his ecu to have it derestricted & tuned by you?
Yes

Can this not cause the bikes engine to have pre-mature ware over the long run? I understand Suzuki has to tune it like that, to meet emission requirements etc. Unless this video you made was just to show us what happens when you just tune the throttle blade positions, and your still tinkering with the air/fuel mixture to be spot on, as well as the correct opening of inlet and exhaust valves. Thanks again for your informative videos, I really enjoy watching them.
@EDW 845, thanks!, and good points. Please consider that when we open the inlets, with no additional tuning, the bike gets LEANER at high revs, not richer, as shown in the red line in this dyno chart: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg the rest of your questions will be addressed shortly.
Its strange that it would run leaner, and not richer, but I guess the air flow or o2 sensor picks up that there is more suction or air being displaced through the system, and compensates for that. I will be keeping a close eye out for when your next video appears. I myself, am a Suzuki fan, and switched to S 1000 RR, purely out of frustration due to Suzuki taking to long to develop a bike that can run with the rest of the pack. If this bike does beat the S 1000 RR, I'll consider switching back, but I'm still a bit skeptic, as BMW has set the bar quite high, but hey, I'm open to having my mind blown and proving myself wrong. They have been there before, nothing holding them back, to be on top again.
So why do they restrict the blades is it to protect the engine?
Kevin Osborne Emission laws
excellent work! very informative!
Brock, loving these videos, so interesting seeing how you tune these bikes. I just have one question in regards to restricting (and tuning for more power) - What (if any) effect does this have on all the stock parts such as the pistons, crank shaft, all other internal parts - Would these parts be more likely to break or wear faster after tuning as such ?
My take on it is this: we are only removing the restrictions the OEM's are FORCED to put in place. They KNOW what is going to happen to these engines after they leave the factory... we are simply allowing the engines to work as if they were not restricted in the first place. And THAT is the key. Don't get greedy - just remove the restrictions and the bike will live a long and happy life.
One other point - the European version does not have the same restrictions at 100% throttle.
Brock I have one question for you that I think is very important, why you use power comander when I have Rapid Bike Racing, our bazzaz, I say this because I earth professionls saying that Rapid Bike is a more " complete " better hardware when compare to power comander, is like you can do more on the tune with rapid bike. If you can aswer this question I am going to be very happpy.
@cobratoxic I will demonstrate this in detail in an upcoming Episode.
Brock Davidson thank you very much, Just another question in my country we only have 95 and 98 octane fuel. do you think we can make more Power Just Puting 98 octane fuel ?
I think that 95 and 98 are just more cleaner that's all, but noted, 89 octane in the US is about the same as 93 or 95 octane in South Africa where I'm from. Not a expert at this, just guessing
Do these bikes still need a throttle blade sync? Or is that something the computer does automatically now?
Great Videos Brock for sure I have learned alot. I do have an R1 and I do watch 650is's videos and want the best performance for my r1. I do know about the throttle bodies and have not fixed the flash just yet But that will get done ASAP.

I hit the like button 3 times for this video :)
Amazing work and explanations. Impressive how injectors are spraying !
Brock, do you know if this throttle restriction from Suzuki is proper to US model or if it is common to other GSXR sold abroad ? I wish we could have a guy like you in France… Maybe Thornbike.
Thanks a lot for sharing you experience.
@atirocky, yes the euro versions are restricted as well to meet Euro 5....Ironically, the US versions are more restricted as California rules are even more strict than Euro 5.
@@BrockDavidson , thanks for your answer. I now own a 2020 R model. It has only a slip on exhaust (Akra GP - no street legal, too loud…). In winter, I ride it in B-mode. Very smooth bike, except at 4000rpm in first or second gear where at steady speed, it feels jerky, like on/off power. Before sending on a dyno, do you think it could be solved by an ECU flash ? (TPS or disabling fuel cutting at deceleration or air/fuel ratio or…)
@@atiroocky do you have any type of fuel management device? PVC?
@@BrockDavidson , thanks for your reply. She is all stock. She only eats unleaded 98 ( E5) or E10 (unleaded 95 with 10%ethanol) as it is recommanded by Suzuki. She is smooth like butter under 3500 and over 4500rpm.
@@atiroocky the simple addition of a pcv with a proper map should cure your drivability issues. If you are into high performance riding, a quality flash with fuel tune would do the trick as well as increase your performance.
will opening the throttle blades earlier and longer create a lean condition? So after tuning AFR with the PCV there's going to be more hp increase ?
@Mark Ramoutar - great question! The AFR with the stock ECU at peak power was 11.8-1, the AFR with the flashed ECU was 12.8-1, I would assume that more power could be gained by tuning to an even leaner AFR, but it's something that would need to be adjusted and measured. FYI: Our goal is to install aftermarket components and tune, not tune for stock parts, so we will find out the answer to your question as the project progresses with these aftermarket installations.
Brock Davidson. Awesome! I can't wait to see the results. you have me thinking about ditching my hayabusa and going for a 2017 Suzuki GSXR1000 with all these informative videos.
@Mark Ramoutar, this link shows the AFR change. Note that it's still quite away's off from the 13.2 line: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg
These are rich lessons. Thx ! :)
When you do the part upgrades is it possible to do a dyno run on it without MR12 so we can see direct comparisons. Really hard to tell what impact the racefuel is having with dyno videos when people put on a bunch of parts then put in MR12 in at the same time. Sort of hides the gains from parts/tuning on normal fuel.
@Cambell Reynolds Mr12 runs will be at the end of the series, used as our 'gauge or standard' fuel so the 2017 GSX-R1000 can be compared to all previous performance makes/models. Until that time, the standard for this series is 89 Octane Shell, as noted in the description above.
That's pretty much impressive....
Awesome stuff Brock! Love that you love the details as much as I do, data means everything! Love the “Ass Dyno” for sure, but numbers never lie! My ass though, has lied to me before, and the data shocked me! Again, well done Sir…..
Have you ever checked this on the v4 tuono?
No need... They all have it.
will the changes to the ECU throttle % affect how the other systems function that control the throttle, like launch/wheelie/traction control etc? or are they independent of throttle position?
They are independent.
thanks for the reply, loving the videos,
great video
Did you guys figure out why Suzuki would do this? The 186 mph top speed thing? Does the gear position sensor alter the stock HP too?
en.wikipedia.org/wiki/List_of_fastest_production_motorcycles#Gentlemen's_agreement_to_end_competition
damn still need full exhaust and tune👍
How does this effect traction control and the ride modes? Although i use neither. And when will this be on market because im very tired of feeling the throttle curve from the factory. I want the throttle to follow my hand
@Eric Roberts, they are all separate - and watch our web store and/or contact our customer service reps for product availability.
Hey Brock! Do you still need a PC when you have the ECU flashed? Tvanks for the videos!
That will be explained, in detail, in upcoming vids. In a nutshell, it depends on the flexibility the person tuning the bike wants to have. Power Commanders make it very easy to make tuning changes - ecu flashes are set and forget.
Thank you!
My bogusomiter kicked in. Of course I could be wrong but, switching back & forth between the two several times it's odvious from the sound that you are not revving as high after your flashed ecu as when the blades start shutting down pre flash. And having the dyno tachometer off lends credence to my suspicion. I hope I'm wrong. I've witnessed too many snake oil pushers, especially in the bike hop up market.
You got me. Try as I may, I simply can't rev a bike as high that has 3 different soft cut limiters in the ecu controlling peak revs. I'm so ashamed...
@@BrockDavidson You can't rev the bike as high with your ecu installed as the stock ecu? & again, why is the tach display off?
??? The tach is off because moments into warming the bike up on the dyno, it trips fault codes from the discrepancy between front (zero mph) and rear (175 + MPH) wheel speeds.
@@BrockDavidson Thank you for explaining that part.
any chance u will do a quick shifter and blipper?
Yes :)
Brock Davidson also is this restriction the same for the European models as mine (UK) pulled 174 on dyno..
although many people think my model may be American as it had reflectors on from wheel and the indicator lights are permanently on, something which is only standard on American models I'm told
@Bang Average Rider, no. The EU version ETV opens the blades at 6K (100% throttle) and keeps them open completely until the peak limiter.
Brock Davidson thanks
Is there any change that the throttle blades are speed sensitive ? The front wheel is not spinning. Maybe they only open 100% after 100MPH + in a higher gear ? ect.
@James Park No. The ETV mapping is controlled by throttle percentage and engine RPM, per gear and per power mode selection (A-C). For this test, we altered Mode A (gears 0-6) 100% throttle - all RPM's.
Why do Suzuki program the throttle bodies like that? Is it for emissions control?
noise and emissions control
fun fun to watch to bad video was to short
@yupi351, lol - we sped up scenes to keep it under 20 mins! Glad you thought it was 'short'!
Hi Brock i have a 05 Hayabusa and would like to derestrict it ive just recently purchaced the clutch mod.would a local suzuki dealer be able to flash
@Joe - most dealers stay away from ECU performance mods/flashing. Your 05 Busa really isn't restricted like today's bikes, but the top speed limiter can be removed and the peak RPM bumped. There are many 3rd party ECU flashing softwares available these days to allow you to do it yourself, or contact Guhl Motors or Ryan Schnitz for a mail in flash service.
@@BrockDavidson thanks Brock
Is it just me or is there no way to view products by bike make model and year on your website?
Yes. But please understand that we are a highly specialized company. Use the product search for your make/model - once an item come up, you can use the checkboxes on the left to narrow down mfg. If you don't see any items in your search, we do not have products available for your bike.
When you are swapping ECU's like that, do you need to code the keys again to the new ECU or can you disable the immobilizer entirely? Also; is de restricting the STAV actuator something which can be done at home without a new fuel map? or would you need to a new fuel map to cater for the throttle blades opening ealier and staying open from 4000rpm onwards? lastly, what tool do you use to flash the OEM ECU's ?
@luke cooper - it depends on the bike. Some we can keep the immobilizer and most we can simply disable it, if required. That depends also, if you mean disable it manually - you can remove the secondary plates. Older bikes might not require much mapping, but almost all newer bikes do. We use MorDefy by Guhl Motors (beta) ftecu, winols and a couple others. Search forums dedicated to your bike to find the one most that owners are most happy about. Please go here for additional info: blog.brocksperformance.com/faq/will-a-brockflash-work-with-my-stock-exhaust-or-with-non-brocks-performance-aftermarket-exhausts/
@@BrockDavidson Thank you! you're videos are extremely saturated with knowledge and experience. I wish you the best of luck and ill look at your blog. Thanks!
so is this the TRE being disabled?
Love your videos Mr Brocks!
What shift rpm is best for this model? Stock bike :)
Sounds like a reasonable, easy question...right? But it depends upon many variables, one of which is that the higher you rev the bike- the more it restricts itself. We remove the restrictions and follow these rules: bit.ly/36aRSEt
Brock do you guys do dynos on Ducati's? Thx grt video!👍🏼
@Mani Singh every once in a while.
+Brock Davidson Does this mean the bike will have less engine braking?
No. We can adjust engine braking independently in the ECU.
Great content! Thank you.
