I've installed a race ECU. What do you want to know?
I've got one on mine and swap between akra pipe and Austin racing gp2r.
Dealer fitted the one on my factory. I fitted a Gabro one on myself to the tv4 I had before the factory. Lift up tank and ecu is mounted on top of air box. Unplug old and and swap for new one. Dead easy. Then do the throttle and handle learning using guzzidiag
Did you have to do anything or is it pretty much plug and play.
