<DIV><FONT color=#000000 size=2>Yep, the wiring all checks out, but tomorrow I
am going to check to make sure the ECM is receiving a voltage above 8 volts from
the ESC. Evidently when this signal wire drops to 6 volts or less, the ECM
starts to pull the timing out. Maybe it is 0 volts for some reason even though
the wiring checks out so far and no code throws. At 0 volts, I assume the ECM
would be full retard which could most definatly be what I am experiencing. If my
car wasn't so loud, I would be checking it tonight. Thanks, Keith.
