Thread: Learning to tune

I have my PE enable set to 30% tps across the board. your transmission settings should be changed so your torque converter can't lock unless you are in 3rd or 4th gear, some people just let it lock in 4th gear only. I used UV scan when I had my dhp, it is much better than the dhp scanning software.

968 sounds like an O2 sensor reading, and if that is what you are referring to, it doesn't really have anything to do with mg/cylinder as that is in relation to air flow.

I was in 3rd gear when this was showing up. My O2 levels haven't gotten quite that high as I'm avoiding WOT until I can get these KR issues worked out. On UVscan it's listed under Fake PIDS (which is why I wondered if their results were reliable) as airflow mg/cylinder and I have values ranging from 69 to 968 varying with throttle.

Just drove to Norwalk Drag today from Youngstown 3.35 pulley DIC showed 29.5 mph that's driving at 78mph. Tune makes a difference.

any idea what was in the tune that caused the kr?

Logged today, results are better, still seeing some KR. LTFTs are closer, max of -10 now. Going to tune the maf some as well as pull some timing where my KR is showing and see where that brings me.

Well, after some more adjustments including a decent increase in cruise timing, my mileage increased from roughly 28 mpg to 32 mpg highway, confirmed by both DIC and topping off the tank before and after my trip to the cities. Only occasional blips of KR showing up during normal driving, which I'll adjust to get rid of. So you guys were right, I could learn to tune.
