I am brand new to tuning and am trying to do some Open Loop, MAF tuning on my 5.3 swaped RX7. The ECM and original tune are from a 4.8L Silverado. I have a wide band and with some advice from a friend tried to log AFR ERR but realized the scanner is showing 0HZ on my MAF. I checked power, ground, and continuity to the EMC on the yellow wire. All check out good. Still no MAF HZ reading in the scanner. I added the PID for MAF status and it shows as "MAF Failed". I don't know why. Can someone take a look at my tune and see if something is set up wrong?
Thanks in advance!
