Alright Gents,
I had a bit of time so I took a stroll down to the old tuning shop in town. Turns out our ECU flash woes aren't just a matter of a lack of interest compared to other bikes, it's a bit more complicated than that.

So this is all explained to me from people at the shop who've been trying to tune these bikes for real, all this time.

The main trick for our bikes is Honda has now gone to a "two brain system." Basically we have two ECU's, one is the 38770-MKJ-A61 people are aware of and think is the only culprit, well there's another under the fuel tank kind of forward right if you look at the parts diagram. So with this new system, it was explained to me that more or less, one is controlling fuel/injectors and the other is controlling throttle bodies. My local shop has actually tried to tune bikes with this setup and they've never gotten it to work because we've really only had the common capacity to flash one ECU at a time. So you can flash the fueling ECU just fine, but then the throttle body ECU will say hey, this AFR isn't meeting emissions, let's open or close the throttle body to fix that since it no longer is controlling fuel the way it thought it was. so the two brains communicate constantly and it's kind of an infinite loop of tuning because one gets tuned, then the other starts to react and change how the bike runs, so then you need to change the other brain and now the first brain is no longer in sync because the newly tuned one is doing something totally different. One ECU is always undoing the work done to flash the other ECU.

This problem persists with the CBR1000RR-R as well, which Woolich told me today they're still working on. I'm confident with the CBR1000RR-R guys wanting a tune along with us wanting a tune, Woolich really wants to tune these damn bikes but Honda is making it super difficult.

Which brings me to my final point. The guy at the shop believes that Honda is looking to force in house tuning soon, similar to BMW and kind of like Ducati how the Akra exhaust for a Ducati comes with the tune in the price tag at the dealership etc etc. So like going to BMW and saying I want some M performance parts on my bike, Honda might be trying to do that too in the near future. Now, this is still a rumor and there's no real evidence of this coming other than the guys who open up these bikes for a living, seeing very similar things happening with Honda bikes that are existing with locked up bikes like the BMWs.

Moral of the story, keep on hoping and wishing that something comes along sooner than later. I'm sure the RR-R guys are helping us in our fight as well. This tune job won't be super simple so it still might be a while even though it already has been a while.

Enjoy your bikes everyone

Thanks for taking the time, that's a great write up. I also wonder if it has something to do with not wanting the ecu to be to be flashed. Kind of like how companies have been fined for flashing ecu's, maybe companies are coming under pressure to make the systems more difficult to modify? I think I like your theory better though, it's probably so they cab charge more for something your bike can already do. Soon we will need to pay extra for the bluetooth, the sport mode, and hopefully cruise control

Honda is a "by the book" kind of company. The reason why US SC77 models had these just forward of the air box and and throttle bodies only opening 73% at full throttle was to meet EPA noise limits.

Wood Material property Font Tints and shades Rim


The US SC82 has seven pieces of foam throughout the ram air intake and HP is reduced from 214 to around 160, just to meet EPA noise limits. Same reason why the US RC213V-S only had around 100HP. Honda is not going to get involved with helping US retail customers convert their street bikes to track bikes.

I’m pretty sure brentuning has a flash for 2021+ fireblade sp so maybe there is hope someone will do it.
I asked them last winter if they were going to develop a flash for the cb1000r and they said there was no plan at that time. If the worst case scenario is the bike stays like it is I’m ok with that too, I just got back from a 2 hour rip through the city and it is a lot of fun, especially after 6000 rpm :devilish:

I just got this email back from Woolich


Hi Paul,

Thank you for the photos. That's perfect.

I can confirm that your ECU is the new type as found in the new 2022 CBR1000RR-R, which our team is currently working on.
So at this stage we can't flash your ECU until we have added support for the new CANBUS style of ECU's.

I think we are getting really close to being able to add these models, but I don't have any dates that I can give you at this stage.

If you would like I can add your email to the 'wait-list' for this model, so you can be notified when support has been added.?

Regards,
Woolich Racing Support Team

That’s the one. Thanks for looking it up. Looked it up at the shop, but couldn’t remember it and had to get back to work.
I'm not sure that's a second ECU. I'm pretty sure it's for traction control.
These are on the RR-R:
PGM-FI UNIT
CONTROL UNIT, SUSPENSION
CONTROL UNIT, BODY
CUSION, SUSPENSION CONTROL UNIT
