I took my RR out of my race car last night to tune a car today and the new car would even start with the RR. I tried calibration, full flash, everything and the RR wouldnt run the car. It wouldnt even make the fuel pump cut on. I had this happen years ago but dont remember what it was, any idea? I have only ran into this switching between cars. Im putting it back in the race car tomorrow to see what it does.
