Default Extremely high FKL with no FBK

Hello all,

Running a COBB Stage 1 91oct tune with 93 gas. Everything has been fine except for a constant massive timing pull in second gear. Around 2.5k RPM and less than 10% throttle I’ll get a -9.84 FKL with 0 FBK. My DAM dropped to .625 but is back to .88X but the second gear timing pull persists. Wondering if something is truly wrong or if the tune may not be flashed correctly.

Get a datalog of this happening, upload it to datazap, and post it here.

If it happens at very low throttle, chances are it's false knock from something on the engine making noise that a knock sensor is picking up, or maybe from a bad knock sensor. Check for rattles.

Knock shouldn't occur with calculated load below around 0.5 g/rev in these engines, so if you're getting big knock readings at loads lower than this, it's probably not real knock.
