This is the 'race only' one on Erik Buell Racing for my year @ $305:

It also says that replacing the ECM requires zeroing of the TPS (throttle position sensor) via Digital Tech (at your local dealer) - is that difficult?
I'm no expert....never touched ECMspy to date....but you can get the cable off EBay pretty cheap. Now....I THINK you can reset TPS on an EBR with ECMSpy. I DON'T think you can do anything else though without ruining it. (NOR would you want to?!). Whenever you pull an ECM...stock, Race-Only or an EBR, it requires a TPS reset.
