I have been pulling timing from the low end cells to try and get the knock to go away when i take off and let the gas out. Im not launching hard just a gradule release of the clutch and gradule application of the gas. I keep getting knock and cant tell if its false knock or not. I got the VE table to +\-3 and have been tuning the MAF. In the attached tune the LTFT&STFT are disabled, tuning MAF on a LM-1 wideband. But cant tell why im getting the knock. I never hear it when it shows on the scan. How the hell can i tell if its false, real, and/or fix it??
