Talked to a reputable tuner and they said they often adjust knock sensor sensitivity with built engines (e.g. upgraded pistons, etc.) as they're prone to more noise.
I guess Access Tuner Race has some advanced parameter adj such as knock threshold/back ground noise parameters. My old Street Tuner doesn't have these. ECU Flash has feedback correction ranges, rough correction ranges, etc.
All that said, has anyone adjusted these? I have very low load, low rpm fine learning correction showing up, and occasionally IAM decrease (forgot at what threshold/conditions IAM decreases...will have to look up again). Whenever I log knock sum it always shows up in low load, partial throttle, etc....nothing in higher load, full throttle, higher rpm, etc.
I was having some AF Learning increases in the very low load ranges, but it seems to be ok (3-5%).
Thoughts? Would you adjust parameters and if so, which ones?
