G4 Storm - LS1 - wasted spark - not firing injectors when cranking

Recommended Posts

Engine: LS1

Car: BMW E36, EWS bypassed.

Management: G4 Storm.

Issues following swapping engine/ECU into fresh shell. Original car always ran fine, never had issues with starting/fuelling.

Car cranks over.

Rev needle sweep works as normal.

ECU connects to laptop.

Rev counter jumps and car registers rpm.

There is only one trigger for the ECU to work from, there always has been, it's the crank sensor, which works off a toothed wheel that's been welded to the crank pulley.

Injectors are not firing when cranking, but we have spark plug testers between the HT leads and plugs, they get a lot of flashing lights.

Tried injector tests on the ECU software. Injectors 1 > 4 click, but they fire 2 injectors simultaneously. Injectors 5 > 8 don't fire anything, no clicking at all. Guessing they are batched 1-4.

It runs wasted spark, so unsure if that's the reason. But help needed.

The G4 Storm only has 4 injector drives so they must be paired up.

Can you do a short PC log of you cranking it over for a few seconds.  Attach that and a copy of your map here.  Here's a video to help guide you set up the PC Log - this is for a G4+ but the procedure is very similar in the G4:  https://www.youtube.com/watch?v=_P1LRANeO4A
