[QUOTE="slow poke, post: 14511910, member: 163268"] On thursday I tuned the MAF with method one and went to 3600rpm in 2nd with limited load maybe .30 and tuned the MAF from the info. It was running around high 14s low 15s up until the 3600rpm and was about 15.7-16.1. I then redid the table again and multiplied all the way to 6700rpm and max MAF AD counts by 1.08 it came out in the end to be 69#/min at max MAF counts. I thought I was good so I re enabled close loop (I dont know if I did this right) and took the car out. This time the AFR was all over the place and was reading lean up to 17.1 at 3800 rpm with a load of .49 and MAF AD counts of 450. I stopped there Do I have to multiply all the numbers in the MAF table again by like 1.15? It seems like it is also lean and I keep multiplying by numbers above 1 on every occasion. Does this make sense? Seem right? The numbers are always jumping all over the place I have a ported blower 4lb lower 2.8 upper BAP and MAFia [/QUOTE]
