Race ECM is not
What you are probably thinking about is the need to recalibrate the throttle position sensor (TPS) voltage that the ECM needs to know when the throttle is fully closed. Either that or the self adjusting adaptive fuel value (AFV), which while settable by a dealer tech will self adjust based upon the O2 sensor outputs to achieve the desired air/fuel mixture, which is optimized for power, the EPA be damned, for the Buell race ECM. Those two parameters, the TPS zero voltage and the AFV, are the only parameters that a tech using the proprietary dealer software can adjust/reprogram. With respect to programability, the race ECM offered to the general public is no different than the stock EPA compliant ECM.
I should clarify... If you have a motorcycle racing license, Buell racing might be convinced to sell you, at a scary high price, one of their fully programable (via PC) race ECM's, but that very unique piece of racing equipment is not available to the general public, only to actual serious motorcycle racers. Nor would it be advantageous to install one on any Buell with a stock engine.
