Excessive kr

[hook]

Adjust fueling according to your stft (10-15 is very high) not with wideband. Calibrate again your wideband and use it only for wot. Then increase pe rate (your map was 85 but it didn't start richen to example 12.5afr so you experienced knock). Put back you timing values from stock map and repeat. 11degrees is too low in those areas.

Thanks, I swapped out O2's and installed extensions. This took care of some slow response issues I was experiencing with FT's. I was able to dial in my STFT's again and they now stay put, and re input OEM spark advance. Before I was having issues with them fluctuating after adjusting them because of my O2's. I was still having KR from 1-3 degrees so I dumped a gallon of Xylene in a 3rd of a tank of gas and low and behold the KR is still there. Have a look. let me know what you think.
