I am having problems with timing using HPT, I have the log file showing when it happens but I'm not sure how to upload it.. I'll be driving at 30 percent throttle position with 17 degrees of timing advance then all the sudden I peg out the knock retard column because my timing will dip really low (3.5 degrees).. I have my main spark advance tables and the PE advance tables basically all the same so I dont understand why my computer is commanding suck low timing. Other than that I'm not getting any misfire and good 11.0 afr's.

Any other spark tables I should look at?
