I’ve been trying to narrow down knock and what I think is a lean spot. LTFT sits around 10-14% while afr is good(probably from correction) and stft is negative cruising but will climb positive into a long wot pull. I’m stuck on if I need to recalibrate the MAF since I have a short open exhaust and a different air filter or find something else. I’ve already unplugged the battery to reset trims once, but the Ltft just climbed up again. Everything in boost seems good after command lambda comes in, but in vacuum it sometimes has KR and the Ltft is showing lean.
I have new spark plugs that are one step colder to help fight knock since I’m running 22-24 psi on a ko4. Also I have new coil packs. Help is greatly appreciated since I’m brand new to tuning
