Novice rewire, crank but no start

Hello

Hoping somewhere out there can help or share any insight on a ecu problem I’m having. I am doing a complete rewire on a gsxr motorbike engine based car, it was bought as a project non running due to a faulty ECU. The loom was in exceptionally bad condition and suspect it was why the old ECU burnt out.

Purchased a new emu Black + wire kit with the intention of matching like for like and getting the engine running. Have now finished reconnecting and are having issues getting it to start. Testing outputs everything fires correctly, but on ignition engine turns over and fuel is pumping, but no spark.

Not sure why this is the case but thinking it could be down to primary trigger issues as the scope during starting looks very chaotic.

Any help in the spirit of Christmas appreciated !

I’m still getting used to this myself, I’m sure 1 of the experts will say for sure, but… Ignition cranking events are enabled, and set differently to your ignition events, Looks like its trying to fire 1+6 3+2 on cranking. Also double check your base timing and see if you need the 2 cylinder offset. (some GSXR’s firing orders are different depending on year too) locking it at 10-12 degrees in the software will stop it jumping around till you diagnose it (I just made the jump to v3 and spent a day getting a 5cyl ST225 engine going in a transit :slight_smile:)
