Mustang V8 COP

[Wayne Johnson]

Hey al, wondering if anyone has setup a G3 on a v8 mustang using coil on plug. Have it all wired and when checking base timing it appears to be 60+ degrees off. We have a 36 -1 crank trigger and a cam sensor. Both are variable reluctance sensors. Was also hoping someone knew what kind of coil dwell I should be using with these Ford OEM coil on plugs. Thank you Wayne

I have no idea on the correct dwell for those coils, you may need to do some measurements...  Have you done a trigger calibration?  You need to calibrate the ECU to match the location of the crank angle sensor teeth so that it nows at what engine position the gap occurs.  Read up in the PCLink help on how to do this.  If you are 60 degrees out will will need to change the offset number by 60 degrees (or -60 degrees).  Here is how your triggering should be setup:

1. Trigger Mode = Multi Tooth/Missing
2. Multi-tooth location = Crank
3. Tooth Count = 36
4. Missing Teeth = 1
5. Sync Level = No
6. Sync Pulse = Yes x1 Cam
7. Multi-tooth location = Crank
8. Trigger 1:
   1. Type = Reluctor
   2. Filter Level = 1
   3. Arming voltages to suit (determine these with an oscilloscope once the engine is running)

9. Trigger 2
   1. Type = Reluctor
   2. Arming Voltages = Check with a scope.  Some Fords have super low amplitude on this sensor.

   3. Filter Level = 2 (or 1 if trigger 2 has real low amplitude)

Most importantly check for trigger errors during cranking...

We are definately having trigger errors while cranking, I have 2 LED's on the ignitors staying lit while cranking, another that flashes intermintently and another that doesn't flash at all. When trouble shooting for no cam signal, we found that the blue wire from cam went to the knock sensor pin location on the ecu connector NOT the cam position pin. I guess now I should look at the rest of the pins to make sure the harness is actually our problem. could this have caused a failure in the ecu?

We have had a couple of looms now with the same problem.  Corrective action has already been taken to prevent this from happening again, sorry for your inconvenience.  In all cases it has only been the Knock 2 and Trigger 2 wires that were incorrectly placed.  There should be no need to check all the other wires.  This would not have caused any damage to the ECU or any sensors...
