Subject: Re: Knock on 150 shot - scan inside...Guru advice please by jonecap on 2008/7/1 0:58:11 Good advice. That's what Josh and I were thinking, but it's good to hear somebody else say it. I can't figure out any other reason why I would see up to 10 degrees of knock and within 200 rpm it is completely gone even when the timing comes right back. I'm going to look for possible harmonics. One other possibility that we considered is the progressive controller is pulsing the solenoids. I have it set to a .4 second ramp. I'm wondering if the pulsing solenoids are somehow being picked up as knock. Any other ideas/suggestions out there? |
