gain does not work

  1. Tuning, Technical Questions
    Car is r33 gtst series 1 with Orginal ECU. I havent cut any of the wire loops in the box (white, grey, brown).I have the wires in these pins. Green wire 41, Yellow wire 42, Red wire 49, black wire 50. Gain set to 1 and rev1 to 7 and it cuts really slow. And its not constant. Sometimes it pauses...
