    Help with 1227302 V6 ECM please

    Hey guys, wondering if anyone can help me with this bin. I am trying to add a code 33 MAF to this bin or figure out some way to remove the code 33 from coming up in the car. Can someone help me with this? I attached the stock bin. Please chime in

    We don't have a very good definition for $3A and I don't see a dissasembly for it anywhere. It's not a very popular car to tune.

    But you are in luck because the two MAF error codes are listed in the TunerCat definition. So you'd have to buy the definition from TunerCat! Excellent product and John has lots of definitions that are just not available!

    0x1DC, turn off bit 3 (ERR 34 low) and 4 (ERR 33 high)
