I cant seem to find anything specific about this but I know it must have been asked.
If I am running an ignition only system with cranksensor, do I need to anything special with the TSP input (ground it? etc.)
I have tried to wire the system up with a 12v ignitor to standard coils and although I can see the ignition lights firing on speeedy (and I have igniter set to 12v and spark trigger to low), the signal I see on the scope at the igniter (when disconnected) looks nothing like the nice short ignition pulse square wave I get when I plug in the speedy sim (which uses TPS to generate revs/spark). Its a horrible positive and negative spike....
I am clearly missing something here but doesnt the spark table need TPS to work?
