ok i been running a pm6 that was chipped like back in the days before zif sockets. this ecu came from a high comp dohc zc so naturally it would be richer than a stock ecu. also this ecu never gave me a cel but i did notice that its running rich and when it idles it like to fluctuate i bit never steady at idle.

a good friend of mine sent me his pg7 to test to see if it would help my car while he chips my pm6. anyway i put the pg7 on and it give me a cel code 8. TDC sensor so i swap out my dizzy with a known working one. i check my timing its spot on at 18btdc i tighten up the dizzy reset ecu and same **** still get code 8. when i plug in my pm6 i dont get no cel and since the dizzy change the car feels a lot better so i don't know what else to do.


this is a sohc zc by the way

 

i really dont know which ecu to believe lol

 

PM6 is the one to believe.. I think you are chasing an artifact of the PG7.. I can't really explain it, but if the car runs normally and you didn't have your friend disable the CEL on the PM6, then you should be fine.

 

nope my friend hasnt touched my pm6 since i havent sent it in yet cause the pg7 is causing me problems. but i think your right the pg7 is trippin for sure.
