Good morning everyone, I have a pretty stock 87 GN with the modifications in my signature, which exception to the 340 Walboro and FPR which I haven't had time to install yet. I don't drag race at all or run the car hard very often, but do have some spirited runs through the gears and an occasional full throttle kick down onto the on-ramp. I never see any knock on the scanmaster during these runs with millivolts reading around 810 and my wideband showing 11-11.5 everytime, but when I hit recall after the run I usually see 2-4 degrees of knock at 810-815 and mid thirty MPH. Am I correct in assuming this is false knock at shifts or something hitting since it doesn't even stay on long enough to show on the screen during the run only at recall? the car runs great, only has 39K miles, running stock chip too.
If you don't think it is knock at shifts, where are typical places to find false knock causes.
Thanks,
