TF and O2 Reduction Error Gain?
I have much better tune each day. I am back to stock APYM spark tables and PE advance feels strong. Tuning AE as best I can and now leave alone until I get WB.
I am putting some TCC values back to stock APYM values and runs better. I notice though that although runs better and idles better less rich. It feels a little more lean at open loop and idle. I noticed heat creep up. Like 200-205 vs 198 before. Granted it is running better more spark and more power
But I was at TF of 5 and bumped from 6 to 7 I notice at idle and off throttle it hangs and holds RPM more. At idle this is causing leaner condition and hotter I believe. Also the o2 error tables were different. I had them lower by about .1 in each cell. I went back to stock so like from .6 to .7 at bottom and .9 to 1 at top.
Is the ARAP an auto bin, maybe I can grab those TCC values for my 305 auto
