A breakout board allowing you to wire a Speeduino/other ecu straight into your wiring harness for a PNP ECU solution.
Every pin from the MX5 harness plug is broken out, including the NC (not connected) ones, for any future functionality.
Front and back silkscreen labels make it easy to find the pins you need when troubleshooting.
4 layer board with optimised power & signal traces, ground fills and via shielding for reducing electrical noise.
2 prototype areas allow you to add extra features to your ECU like extra inputs/outputs, conditioning, etc. I use mine for extra grounds!
Large vias allowing you to run large wires into them, or bunching multiple wires together. Large spacing to make probing a little safer, for less risk of slipping and shorting something! With a little carefulling, you can also solder from the top, if you like living on the edge.
October 2023 Update: - Extra areas added with Switched 12v, Permanent 12v and GND vias.

Please note, this is the 1st revision prototype board - some of the labels might be slightly ambigious due to information coming from multiple online sources, and several spec variations between models. Always cross reference this data sheet for the function of each pin: https://www.miataturbo.net/attachments/ecus-tuning-54/224948d1602912806-04-msm-ecu-pinout-nb8bc_oem_ecu_pinouts.pdf
