ECM Difference

[augustus_01]

What difference is there, if any, between the ECM for the 1125R & 1125CR? I bought a used ECM tuned for the Barker's exhaust for an 1125CR, but I have an 1125R. Will I be able to use this ECM? The only difference I know of between the two bikes is gearing.

That's it is gearing from what I have read, yes plug it in and ride!

plug it and play it

Here's the email I got from EBR:

Speed calculator is different to match gearing so your speedo reading will be wrong.

just the same on japenese crotch rockets when people start jacking with front and rear sprocket size(s). takes a speado healer to fix it, but they dont make on for the buell. its only minor anyway, not like youll be doing 80 and reading 40 or something. really, i dont even know, but maybe like 6-8 mph off.

but also, all bikes have a "factory error" thats like 7% or something in that ballpark. i have gps on my bike that shows speed. and its more accurate IMO when compared with the police radar trailer thingamajigs

Cool - I know what I'm doing tomorrow!

The Barker exhaust and ECM changed my 1125R instantly. The bike is epic now! I just added the K&N filter and that improved it as well. I think it's the best sounding exhaust out there...not just on Buells. I get looks from HD riders all the time...they're like..."wtf?". I just smile and wave boys...smile and wave.

Yup. Stock ecms keep the airline fuel ratio at 14.7. But YouTube get the most power at 13.2. Race ecms adjust to this ratio at wide open throttle and other areas of the fuel map. Does other stuff as well. Itjust runs all around better and more efficient

Airline = air

YouTube = you

Good job autocorrection

I might have ordered the wrong ECM and not sure if EBR had a chance to correct it before shipping. I need the CR. We can swap? Mine is for Barker's too.

Terry,

Do you know for sure you ordered the wrong one?
