Yes, I've seen the other posts with similar problems. Bear with this ATap newbie for a minute. The car is the dreaded '98 M6, 5.3 heads, 224/224/114 cam, FLP long tubes. My tuner was seeing the WOT knock retard and crappy timing when we were on the dyno after heads/cam/headers install. (An install that included new plugs/wires/injectors, too). We determined it was false knock and he copied the high octane tables over the low octane tables for me.

Now it's about five months later and I finally picked up a laptop and Autotap... and my first WOT runs are showing 3-4* KR and crappy timing. If my low octane tables have indeed been overwritten, how is it that I'm seeing such poor advance?

I have attempted to attach a word doc with the numbers from my WOT run... I'd be much obliged if anyone would take a look and let me know what they think... and also let me know exactly which parameters I should be logging.

Thanks a lot,

Honestly, it looks as though your timing is set awfully low to begin with. Even a high compression street motor on pump gas (ie 11.7:1 to 12:1) should not have timing that low)

If you have the dreaded 98 false knock either change your knock sensors or disable your knock retard.

Good Luck

I'm very interested if other '98 owners who have had their low octane tables overwritten have seen this problem... Anyone????
