Mspnp2 on 96 miata new engine same ecu no start
 
I built a diymspnp2 and have been running it for at least five months on a 96 miata with stock engine.

New "race" engine was just installed. Everything seems to be of sound build and electronics seem to check out. I know this because we installed the old STOCK ECU and got the engine to run.

And that was so very exciting. But the mspnp2 all of a sudden doesnt supply spark or fuel and no rpms. So I feel something went wrong with its ability to read the CAS. Also we installed a 36-2 trigger wheel on the ati damper. With this it has a nb crank sensor.

So the MSPNP2 isnt picking up on the cas or trigger wheel. But started and ran on the factory ECU.

DID I somehow kill the mspnp2 while we were installing the engine? I checked the board and there was a faint burnt smell coming from around the 76 pin adapter board.

So no one has any ideas?

Is it a DIYPNP or an MSPNP2? Take a composite log. How did you wire in the NB crank sensor and you are sure it's correct?

Diypnp2, crank and cam dont show up on the logs. I cannot get a log at the moment since the car is 3 hours away from me. The NB crank sensor was hooked up by my engine builder and he knows what hes doing.

Ok, here we go! Will this work?
