Not firing all coils

Post by snax »

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

havent checked the map, you you need to enable twin spark.

coil and injector angle etc do nothing when not using sequential.
