So I live in Colorado, I've been data logging and messing around with fuel and timing for the car, but I still get knock. I cant seem to dial in the fuel. I am new, I've only been messing with the fuel and timing for about a month. Ive watched a lot of videos on you tube on fuel and timing. Just reaching out to see if anyone might have some tips, or can help with the tune. I resorted back to the base tune. This is a base tune run that I put back on the car. I've tried the Maf tune but had even more knock. Appreciate your time in reading this. Car has 170,000 miles, that's why I'm replacing/refreshing lots of parts on the car.
