Good day. Need help. As title said, running rich at wot. Tuned to 10.8, but as soon as in WOT afrs goes to 9.3. It happened after I calibrated MAFv to read up to 5volts, because stock table goes only up to 4.69 and car was running a bit lean. So after I rescaled maf table, went for a run and as I thought, car was running rich. During calibration I noticed that afr still the same. Returned map which was before rescaling, car still runs rich. Car is Subaru Impreza WRX wagon 2007(hawkeye) with stock ej255, vf35 turbo, fmic and walbro 255. Was reading that stock fpr may not keep up with walbro and start overfueling. IDC are 105%, boost 1.5 bar

 

if you rescaled the maf table then you need to alter injector scale for a start and the maf scale to match the new maf table voltage
