Not firing all coils
Posted: Mon Aug 29, 2011 8:47 pm
quick recap of my last few post. Im working on a ford 351w motor, custom 60-2 crank wheel with sensor at ~306degs, custom single tooth cam signal, GM LS2 coils.
Engine firing order is 1 3 7 2 6 5 4 8, I have double checked all of my wiring...all of the coil outputs are wired to the correct coil according to the firing order. I have the coil and injector angle maps set to 90degs apart for each cylinder. I am not trying to run seq injection or ignition at this point, the tune i have created should be batch fire and waste spark.
The Engine will start and run but only runs on 4 cylinders... 1 2 3 7. I do not get spark on the other cylinders. I have swapped coil packs to rule that out and I have also swapped ECUs with my BMW to verify the ECU is good.
I have attached the map for you guys to look at to see if anything looks goofy
