Since idling IAT's tend to be high even when IAT's while the car is moving are on the cooler side. Once I have the MAF scale to where I like it I'll start to mess with the temp compensation. Just curious if anyone has done anything about it. Also if you didn't know that there was this variation in fuel trims due to temperature change you'd never be able to get your MAF dialed in and chasing your tail until you realize this.

The simple solution is to zero out the IAT compensation table while scaling the MAF. You should really do that to all compensation tables while calibrating for that very reason.
On ECUtek you fill the table with values of 1, RR is 0.
The IAT compensation isn't a simple hot/cold +/- as it reverses as air volume increases too. I would return the stock table when you've done calibration.
