got a truck come in without a maf sensor and does have an iat in the intake with 80lb dekas.
havent been able to get it into closed loop. they wired both ho2s to bank 1 and installed on downpipe.
readings on ho2 dont really fluctuate much they stay around 450mv. any ideas guys ill post the tune to see if im over looking anything?
havent really messed much with maf less system any advise is greatly appreciated.2000 silverado 78mm 80lb deka 3 bar.hpt.
oh and the readings on the map sensor are still on stock even though the os for 3 bar has been applied, he is waiting on the map sensor to get here
so for now running the stock. would that do it?
