I have a 97 Corvette A4. 5 angle valve job polished intake/exhaust ports, cold air intake, 3.15 final drive gear, 1.8 roller rockers, beehive springs, throttle body bypass, 160 thermostat, tranny cooler, TCI 850hp 4l60e (they said if I break it they give me a new one within 3 years mileage unlimited so w/e! ), TCI 1800 stall, tune by me.
With that being said.
I have noticed that my knock sensors are acting up at WOT regardless of what RPM I start at, and happen randomly, sometimes a WOT run will yield no knock at all (all on the same test run). It happens mostly on a 2nd gear WOT starting at 2000 rpm taking 8 degrees of KR. Thats a lot of potential power lost.... Also happens randomly in the 6300 rpm range right before a shift from 1st to 2nd...
I'd like to know if anyone has encountered this issue with the LS1 and what any recommendations might be. I am thinking of desensitizing the Global Knock sensor table in the 95 to 105 map range but the values do not have any units to them, if anyone knows what value will work best, that would be great.
My other thought is to change the tip in sensitivity as well but again, I don't know the units and by how much to increase them.
Yes I have a WB, yes I log it, but its logged on LogWorks because yes I have hpt standard. Regardless, I have matched up the graphs and my AFR is averaging 12.8 at all the WOT tests.
Please PM for tune and scans since I have had no responses thus far. Thanks.
