me neither John as it's a different ECU than the majority I think and it doesn't have a tuner potentiometer on it (if i'm right) so any idle mixture discrepancies from different exhausts fitted etc have to be done via software or a power commander. Maybe someone will add some better info.
only major issue is it doesn't have the pose value of a 748 servicing costs a fraction of 4v motors and on the road it produces good usable power
