It was suggested on here but I had to try it for myself. I am not to up on worksheets anymore and wanted something that was pretty easy to use. I used a custom MAP/Histogram that is based on MAF Frequency and AFR(posted in the other thread. The tables are setup so the difference from commanded and actual is displayed in a percentage just the same as LTFT/Wideband. I plotted the VE table just the same as I would if I was tuning for VE, but instead used the % error from the MAF table and after two passes was done. The ability to make our own custom MAP's is great and no more excel!!! Not to mention the guy is tickled pink now with his car.
