here are the tables from a tuned rom (petrol) note the closed loop fueling target is 14.7 + (closed loop target value) eg for above 5600 rpm load say 1.0 target AFR = 14.7 + (-1.319) = 13.38 , other compensations may apply some unknown. open loop = WOT and aggressive throttle movements 02 sensor not used only LTFT compensations applied that were learny on closed loop closed loop = partial throttle with slow or steady throttle movements feedback loop using 02 sensor to correct AFR using STFT and LTFT Last edited by steve99; 08-14-2015 at 02:14 AM. |

If you drive fast canyons only, that's a different story. But that's not normal driving.
