ok here is my problem, I just bought my s13 and it came with a apexi safcII and its was fine for a week or so but last night for some reason the car wouldn’t respond to the usual settings. I had to change everything to positives. I was wondering if i touched something by accident to reverse the settings. The numbers seem to be similar but only in positives now. If there is someone i could go to in toronto on close by to help with it would be good. I need it tuned really well but a temporary solution would be much appreciated. Thanks guys!! ---

Call me at 416-455-9521 . I have a lot of experience with the safc from install to tune . I can check it out for you , my guess would be to reset it totally and re-input all the original setting such as maf , trottle , low set , high set , # of injectors ect… This sort of thing usually happen when you have a bad ground or a loose wire , that’s Y it’s always better to solder all wiring . ---
