I'm looking for a 94-95 Cobra ECU with the calibration code of J4J1. I have a 95 Cobra and I'm using a 94-95 GT ECU to run the 19# injectors I currently have in the car. The injectors are used and are crap and make the car run like crap. I've got 24# injectors to be installed but I don't want to use a chip or a different MAF to use them.
