I used to keep my AP mounted in my car all of the time. Then this past Texas summer my mount melted off the windshield. I haven't bothered to put it back. It's actually nice not to stare at the damn thing all of the time. I had all 4 cylinder ignition corrections showing, plus OAR or fuel level input for mixing E30, and AFR's and the fact is, I never "felt" the minor ignition corrections, it was interesting at best to know that it happened at all, and ultimately I didn't change how I drove because of it.
The only time the AP was really useful was when I tried the whoosh coil packs. After a few weeks my car drastically lost power, and I recorded the insane corrections I was getting. I sent the datalog to whoosh and he accepted the return.
Set your tune and put your AP in the glovebox and stop monitoring it for anything more than occasional use.
