Hey guys,
I am seeing different AFR from bank 1 to bank2 due to differences in the MAF voltages. So I tried to correct this by increasing the value in the MAF fuel table for bank 2. It doesn’t seem to make a difference. So I tested to an extreme by increasing the cells surrounding the .86v by 100 (actual increase in value, not percentage) but I still see no change in AFR for that bank. I followed the tuning guide supplied by UpRev. Can someone that has experience with UpRev give me some guidance? thank you.

1) Is MAF sensor A correspond with bank 1 and MAF sensor B with Bank 2?

2) Am I able to balance the AFR’s by using the MAF fuel table, or do I need to use the fuel trim table?
