    You're genius!!!!!
    replayed the log with the new ADX, and what was 23000 SA is now -3.867
    I have factory spec 4 degrees advance at the distributor. Does the computer factor that in, so in this instance we have 4 ATDC?
    With timing that late, I could see the spark jumping to #8 cylinder.... = fireball.

    What advance range should we be in with low RPM/WOT/low load?

    At warm idle, the data says 10 degrees advanced.
    But at the damper checked with a timing light its 4.
    I have verified the marks are correct on the damper.
    I have set base timing to 4 degrees with ETS disconnected.
    Now I should either read 10 degrees with a light if the computer accounts for the base time,
    Or 14 degrees if it does not.
    Why the discrepancy?
