    It doesn't matter what sensor you're running on an NA setup. All of them can read vacuum. 1 bar, 2 bar, 3 bar, doesn't matter

    Just put the right MAP sensor data (linear / offset values) for the sensor you're running and go with it.

    All it's doing is reading vacuum... and any of the common MAP sensors can do that. The computer and MAP sensor don't care whether you get into boost or not.

    IAT is showing as -40*F which is typically what you get when the sensor isn't connected or is bad.. so I would address that first

    Fuel trims start off really high but do come down some. Not sure if it's because of the IAT sensor issue or not though. I'd figure the IAT issue out first.

    I did not have the maf sensor pluged in because I assumed i could run maffless.. Pluged that back in and had the tune adjusted.. Took a new log with the IAT reading properly.. But i lost that with my computer crash. So tonight i will post another log.
