what ecm are you using when doing a ls swap

ive heard lots of good stuff about the holley hp system. i just wish there was a little more feedback. when i was talking with wegner they said they did a lot of "messing" with it on the dyno by pulling fuel out and trying to hurt the engine. they claimed that the holley relearned instantly and kept anything bad from happening. my knowledge of how all this works is minimal so maybe others will be able to fill in the large part im leaving out.



if i go gm i will either buy the gmpp harness and rework it for remote coils etc. or pick one up from psi. speartech gets lots of good reviews, but i cant justify the 700 over the gmpp or the 500 over the psi. ive never really found any difference between the e67 and the e38s in all my searching.
