Knock count isn't a big thing. Knock retard is what you really need to watch. You're showing 1.1* retard at idle......something isn't right there. Email me your log and I'll take a look at it.

Default Malf 36

Hello,
94 LT1 started running rough a few weeks age. then 2 days ago, car started cutting off randomly. always when i am almost home. i live 30 minutes from work and i drive in city and rural traffic so car has enough time to heat up. so it seems that the problem maybe be heat related but I also read here that it maybe the ICM. either way, i really didn't see an answer to the fix for a MALF 36 error.
I also have a Datamaster file that I can include if someone would like to look at it.
Thanks, Scott

If you end up going the opti route make sure its a new GM save your self a big headache
+1 on that... going thru the same **** myself, I replaced the ICM twice (auto zone warrenty luckily) and the connector to it, coil was fine. sent my MSD opti back to MSD to fix it get it back and same **** happing all over again sending it back to them and hope to get a new one back this time. then Im buying a stock GM unit and selling the new one. I dont trust it MSD anymore
