    Question Knock Retard

    Ok I finished my head, cam, long tube, therm., and plug wire install. My question is now I have 4-5* of knock retard :hammer: at WOT where I had none when the car was stock. Is this a tuning issue or an install issue?

    Can I tune this out? Do I need to take the car apart again and re-do something? Or could something be loose and it just needs to be tightened down that may be setting off the sensor (ie exhaust)? I would like to get this issue resolved.

    The car is definitely stronger now with the install but I think it will be stronger if I can get rid of the KR.

    Thanks
    Jon

    You need to get it tuned. You are most likely running lean.

    Sounds like that Bad Luck might be rubbing off.

    I've had up to 10* of knock retard at WOT but I only did a long tube install.

    Get HP Tuners and tune it yourself.

    I have HPTuners, I guess I need to get the wideband to tune it myself.

    OK guys...This is what I have found out. My Y-Pipe is knocking on the brace. I am working on getting the exhaust hanger back on the car.

    I am curious...I did 2 back to back WOT logs. I logged 0 KR on the first run to 100 and the second run to 100 I logged 4* of KR. Could it be because of the Y-pipe or would true knock come and go like that?

    While driving the car is when I heard the rattle under the car and checked to find the rattling Y-Pipe.

    Yes that could cause a false knock.

    I'm glad to hear that I'm not the only person that has a y-pipe hitting the floor pan. Right under the diver side.
