without delving into too much detail, ive been researching running an I6 (not the LL8) with an e38 pcm since i know the impala OS runs a V6, I have found where i can individually adjust the injection timing, but i was wondering if and where i could adjust the spark base ignition timing. i.e. the ignition relative to the crank and cam position. I know this may be quite a feat, but im up for a challenge, hell i've always wanted to learn assembly language anyhow.
