Well the speed* ECU is designed for the total speed* setup. Cams, pistons, pipe, oversized in jectors. So you'd probably need a pcIII anyways to make it run right. Your better option would be to go with the pcIII, and if you just wanted the ECU for the extra rpm's, I think the pcIIIignition modual is available now so you can increase you rev limiter and change your timing.
