#5520, "RE: yet another MS question" In response to In response to 2
Most people that run MS have that common sense and know how there car is running. The important gauges you would need would be wide band, oil pressure, coolant temp, fuel pressure and voltage. Of course there are some other important gauges but those imo should be mandatory when going full stand alone with MS. If your anal about the check engine light then imo MS is not for you.
