Hello all recently I acquired a 1998 R/t and I have slowly been going through the truck trying to find out all the mods done to it as it s a pretty extensive list and I purchased it from someone who had no idea what they had. One of the first things is that the motor is run by a Fast Classic ECU, but it is being run in concert with the factory ecu. the wiring from teh fast ECU goes into a metal box with the name FAST Track Performance on it this box then duplicates some of the outputs sends them to the factory ecu to keep it from popping any check engine lights, making the dash work keeping the factory AC and Cruise working. And i assume handling any transmission duties, Then a second set of wires goes straight from the FAST stand alone directly to the engine to run the injectors sensors etc.
I am curious if anyone know anything about this Fast Track Performance Box some of the long time members might know as i know the ECU itself was made in 2001? Anyway any help would be much appreciated!
Thanks
