This is driving me little nuts. When I got the car it ran lights out, no knock or anything. The MAF craped out and I replaced with the translator/LS1 MAF. I set the translator up per instructions, got knock. Switched the WOT to (3) on translator and still got knock. Could the MAF be the issue? I might sell the translator/MAF and get a remanufactured MAF from Kirban. All the gauges seems to be showing everyhing in working order, A/F:10, O2: 800+ getting into boost, etc. I have only gone half throttle as I see knock on scanmaster ranging from 2-8 at approx. 15 lbs of boost. The car runs on E85, and I am hoping the octane on the tank of fuel is just not up to par. Otherwise I need to find a good shop in south Florida to help ID the issue as I cannot afford to replace head gaskets/rebuild engine. I have read false knock on a couple threads, but I cannot find any exhaust pipes hitting anywhere.
