I started a thread in the tuning section but I thought I would link it over here for the guys that may not frequent the tuning section. I bought the innovative OT-2 wifi intere face that allows you to use your iPhone to monitor a wide variety of parameters while driving, Rpm's, timing, mass air, IAT's, fuel trims etc. I bought a cup holder mounted phone mount to hold my phone while monitoring it.
