Not yet. I only discovered this recently, so I'm just going to keep this in mind while I continue to dial in the maf scale. I'd want the fuel trims to be a bit in the + side on hot days and a little in the - end in cooler night temps across the board aside from idle. 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.
