Intermittent AFR's wildly swinging
Hi all,
Trying to determine what's going on. Setup FIC2150 E85 SD Tial VTA Bov EGR Delete Seems more stable 1st thing in the AM. Idles 14.5 - 15.3 or so STFT close to +-2% Cruise fine 2800-3k for 5 minutes or so then AFR's start swinging, on Decel injectors stay Rich and don't shut. after a bit it will recover eventually and be stable for a bit and Decel normally. Any thoughts? o2 sensor MAP Sensor thanks |

I reset trims and LTFT Mid was heading towards -10% after a few cycles so I'm guessing that's what the issue is. Where should I remove fuel from RPM-VE or Map? I don't want to screw up idle I attached a log file for reference. Thanks for your help. I appreciate your input current settings https://lh6.googleusercontent.com/-U...eenShot001.jpg |
