2008 C6 Vette with E38....
I have the MAF tuned pretty good and now I am working on the speed density tuning. MAF disabled, Dynamic High RPM disable set to 8,000 rpm, Fuel Trims turned off, P0103 set to MIL on 1st Error. I can crank the car and let it warm up and begin logging commanding 14.1 AFR. Car is running very rich at 12.0-12.5 AFR. I log the AFR error and copy paste to the VVE table. Interpolate as much as possible within the VVE zone, Calculate Coefficients, Flash the tune to the car, and no change in idle AFR. Still 12.0-12.5 range. What am I doing wrong? Is there a fueling multiplier table somewhere I am missing? The car is for sure in Open Loop and the MAF is showing as failed. What am I missing? I even took 15% from the entire VVE table with no change in AFR. SD Tune attached. Thanks
