ok, so we all know the 0411 PCM is capable of CPC, and some of us know the 4.3 S10 also uses the 0411. The 4.3 doesn't use CPC though, it uses some kind of distributor setup, much like that of the 5.0 and 5.7 vortec engines. has anyone converted a 4.3 to run on a 0411 with CPC?

wiring pinouts for the S10 and typical V8 0411(trans am IIRC).
