I have accesses to a Mustang chassis dyno and I was wondering what the most efficient way to tune the MAF & VE tables? I have done it using a NGK AFX wideband with the OL set to 13.5:1 AFR, but it seems when I have all the cells close to or under 1% and then check it in CL the LTFT are around 7-10%. Would I be better off using the LTFT or STFT to dial in the tables if I am going to enable CL once the tune is finished? On a really good tune or OEM tune what do the fuel trims look like min to max on a daily basis?
