Figured out what my issue is. The Pro-M meter I have is a 4 pin setup, so naturally that code is going to pop up. The car runs great with the meter, regardless, but I'd like to get my Abaco meter back on the car... something went bad on it, as the car won't stay running with the same injector calibration as the Pro-M (01SVT 30lb.). I've read there's been some issues with the Abaco meters, but they're taking care of it apparently.
One thing I found while looking around, was guys cutting the IAT wires and running a Lightning IAT sensor... this is another option, in my case. With a diablo predator hooked up and displaying data, the IAT is locked in @ 100 degrees.
The light stays off until I start the car again, so for the time being... I just clear the code out right after I shut the car off, that way when I fire it up the light isn't on for the duration of crusing around. And I want to reiterate the fact that the car is running very strong now, with the Commando tune-up... it settles into 12.9-13.1 @ WOT and has a ton more midrange and throttle response. Amazing.
I'm going to spend some more time on the motor and then start tuning for nitrous hits again... it's been a while since the car's been on the jug.
