Logging IAT/MAT (Manifold air temp) on stock ECU

[scheides]

Not long ago I had my IM off while doing a headgasket, so I took the opportunity to tap it and install a GM IAT sensor.

Using a hack from evoM, I can now log manifold air temp on the stock ECU using a GM IAT sensor. Works great! This will be an invaluable asset for tuning, and combined with my 3-bar map sensor, guess what's next?
