    I know better, but I'm gonna ask this in a way I hope you'll understand It's a fair assumption with the PO's expense of installing a "Race use only ECM"(lol), it would already have the race program for the Buell race muffler and airbox the PO also installed. So... ipso facto, how would downloading the same damn program change a thing?

    If your car runs a little funny tomorrow are you gonna break into the ECM and download a "tune" before checking anything out at all? Seem silly right? Why treat your Buell that way? It's at least a 12 year old machine, probably more like 16... Perhaps a rubber intake boot is leaking? Dirty injectors? Plugged fuel filter/sock/weak pump? Na... definitely the solid state gel filled ECM

    Your assumption of a fuel mixture issue without any actual diagnosis whatsoever may be correct or lucky or wrong, who cares. But the problem being caused by the 'tune' is Slim to none and Slim just left town. Whatever, I'm trying to help you avoid the same ol' thing we've seen here over and over and over (search) and OVER. Even the guy passing you the free tune says the SAME THING, but you sound like you have convinced yourself to take the blue pill anyway. See ya on the other side Neo.

    BTW, you aren't "mapping" or "tuning" anything, you are pressing the upload button on a map you got off the internet for free... and will get exactly what you pay for.

    Sir: My ECM knowledge is minimal and my tuning capabilities are non-existent, but the below link should give you solid guidance and direction. As memory serves but not mentioned here....The Buell-issued via Harley Davidson "race" ECM has "race only" stenciled in white ink stamped on it. The EBR-issued "race" ECM has "race only" and a SKU identifier on a white and black label affixed to it. Should help you identify which one you might have.

    Great info as usual Barrett. The OP should also be informed that these "race" ECM's are physically identical in every single way to a stock ECM*, and no matter what is stenciled on the ECM, and there is no way to determine the fuel map thats in it besides going line by line through the entire data block.



    *With the exception of the BUE-3D firmware, 16-bit baud rate true race ECM used by the actual race teams.

    And you know how to fix it yourself….


    I fail to see the issue.
