Need help guys..

[Jwilson140528]

Bought my Hayabusa and was gonna pay to get the ECU flashed. Opened the seat to install a battery tender and found this.. turns out I don't need to get it flashed after all. I guess this is good news?!?! Says shift light at 10,500 and rev limit 11,500..

Sounds like you lucked out....what did you need help with?

Of question is if the fuel map was edited, if deceleration fuel cutoff was disabled...Is there any evidence of who the vendor was? They would likely be able to provide you the changes by VIN number.

Could be good news... But you can't tell who did it or what they did. I had MPS do mine when I installed an air shifter. The ECU came back with a number stamped on it. And a data sheet with that number listing what changes were made. About the same when I had Schnitz do my Gixxer.

11,500 is too high, there is no power there, just over rev and stress on the engine.
Peak hp(with full exhaust and large airbox mod) should be low to mid 10k rpms, maybe lower, and falls off quickly after.

What would they have done with the flash? I mean do different tuners do different stuff while inside the ECU?

I totally agree. There is no power to be made there.. yeah there is no way to tell who did it. Just was reaching out for you guys help. Thanks in advance for any knowledge you guys have

Yes, they offer a list of options for the customer to choose.

Timing is retarded in the low end and they can disable that. The top speed limit to which all those manufacturers agreed can be disabled. There are a quite a few options.

I wonder if any engine work was done to merit this change. @Jwilson140528 do you know for sure the engine is stock?

YES... You have no way of knowing what has been changed. Or if it's really even been flashed. May have been a home brewed flash. Some guys know how to do that correctly, most don't. Everybody can buy yellow tape...

Email, and then mail it to Frank. Worth the $ to learn what switches were flipped.
Tell him you were referred by the org.

That is a good question...if someone did it themselves they could have done anything however it looks as though they removed the limiter and raised the RPM limit.

Many here use home based flash programs to good effect...if you are unsure, it would be worth your time to send it in to ensure it was done right.

I mean I'm not to unsure because it runs like a scalded dog. Driveability is awesome and it really runs great.. I mean it has a BMC filter and full yoshimura RS3 system on it. So I'll just leave it alone. Runs to good not to have a good tune in her

I have no idea of it's stock inside. I haven't looked. I'll take a look at bolt heads etc to see if they look like they have had a socket on em. Good idea

Sounds like a good plan, if it ain't broke, don't mess with it...

I would run it as is, till something goes wrong Then you can open the can of worms. You said it runs great.

Some flashes include an air/fuel map, by request, most don't.
A basic flash usually gives more timing at lower rpms/smart tre(noticeable), removes top speed limiter, turns fans on/off 10-15°f sooner.
Later models with more features have more options.
But a flash is well worth having done correctly.
And I agree, if it runs good, leave it be.
