TunerStudio reports the VE fuel table is the only difference in the the two .msq files. Is this correct?

Are there any other settings that I need to change? I just went to the IAT and it was acting at tad odd at idle on the first start, but otherwise seemed okay. This car never runs quite right till it warms up. Working on that.

Does the MSPNP use the AFM data at all?

Jon

It's fine, it was "acting a tad odd" because you have to tune it.

The MSPNP uses the air temperature data if the AFM is plugged in, but not the air flow potentiometer.

the only difference is the internal configuration for the air temp sensors. One being the OEM one inside the AFM, the other being that of the GM sensor.

If you use the wrong firmware/project your reported air temperature readings will be off.
