Sadly there is no oil pressure, which would probably be the most valuable. Ultimately the AP “always paranoid” saying is true. You should stick it in the glovebox more often than not. That said, I do keep mine going 100% of the time. Monitors are boost (obviously), coolant temp so I know when I can consider pushing the car a bit. Remember coolant will heat up faster than oil so 10 minutes of driving is really a better gauge, DAM (should never ever change), fine knock learn, and fine knock correction are the ones that sometimes do register and give me that Always Paranoid sensation, then final AF Learn 1
I simply opted for actual gauges in my obs and when i get around to installing them my wrx. The ap was annoying to try to read while driving.
