Thought I'd introduce myself; My name is Bop and I'm currently converting my 13B Miata to EFI. I'm using an MS3X from DIYAutotune and a standalone power circuit for all of the new electronics as per Aaron Cake's recommendation. Car is running in ITB mode as I'm using ITB's with a Nippondenso 24/1 CAS and (currently not firing) Mazda RX-8 COP-style coils.
Currently trying to figure out why the coils arent firing (not even in test mode), will scope the signal wires this weekend. Also no VR signal atm so checking the correctness of the jumpers on my MS3 board as well.
