Well, went for a drive today, started the car, (very cold start as I only really drive the car once a month). Car idled for a few seconds then engine died, straight to 0 rpm.
Tried to start again and the engine wouldn't turn over. I smelled a electrical fire. Paniking I ran to the trunk and undid the battery, then looked for the culprit.... my DIYPNP. It's served me 4 years, Idk if it's because I don't drive the car often, or a little spider was caught between a fuse and a spark place, but the magic smoke has poofed. The motherboard traces are burned too...

Trying to weight my options, a few questions as it's been years since I built this thing...
Section R29 and R30 seem to be the culprit, if I remember correctly this if for spark to engine right? I'd like to know what cause it if it's a failing part on the car.

Obviously the motherboard has been burned through. I just want this car running again (turbo 1.6L) what do you guys recommended as the definitive 2022 ECU system for a 1993 NA miata.

Sucks that this happened, it was such nice weather for turbo time :(

edit --- buying copper trace wire and replacement resistors, I am going to try to repair this john... still open to recommended ecus, I'll probably go with MS3pro if this doesn't work out.
