I am doing a 1.9 turbo build on a 1990 miata. It was speedyefi before so I kept that. Now with the new engine and audi r8 coil on plug conversion I am not getting RPM. It could also have to do with my 36-2 trigger conversion, I'm not exactly sure. I have more info in my build thread and I'll attatch my tune and a datalog of cranking here as well.

 

I got it sorted out. Turned out my crank position sensor was too far back towards the engine. I put a nut in between the sensor and the block to act as a spacer and got full sync. And some starts.
