I have an inline four pr3 ecu that they remapped for me. I was wondering if anybody has had any experience with thier ecu's. so far this thing is garbage everytime I put it in reverse I get a code 73 (random misfire cyl 3). I have replaced all the ignition components ie spark plugs, wires, cap, rotor ect. I have also gone as far as hooking up my friends ZDYNE and the car runs fine no check engine lights or anything. I guess my big concern is if anybody has got any shotty products from them before. any answers would be appreciated.
