<DIV><FONT color=#000000 size=2>The way I see it, the ESC, EST and ECM are the
only 3 things in this setup that can control advance/retard in this computer.
When I go through the normal routine of setting my timing at 6deg BTDC with
timing connector disconnected, that works out fine. Then, when I plug the bypass
back in, the timing RETARDS a good 24 degrees. I just replaced the ESC module
because I thought if it was bad, it could cause full retard but it wasn't the
case. I took all spark retard out of the chip and it still did the same problem.
Unplugged knock sensor-samne thing. Swapped ECM's and it still happened. TDC has
been verified many times with a piston stop. What electronically could be
causing the massive timing retard? The EST has also been replaced and verified
with a spare one. All wires have been rung. Oh, boy. Thanks in advance,
