MS3 basic made by Reverant. Fits inside the OEM ECU housing and has the Miata harness connector so it will mount and plug in like OEM. Served me great for 4 years but I am doing an 8hp50 swap and have decided to go with a different ECU based on that.
Daughterboard has USB out so no special connectors needed to connect to the ECU

Price : $850 OBO
I am based in Iceland so I will do my best to make shipping hassle free.

 

This is a trustworthy seller and a great deal on an ECU. He's also a great guy.

Good luck with the sale!

 

Just to avoid any confusion, this is not really a full Basic, but a very "Lite" version of it (hence "Basic MS3 3.1L"). Its more like a very early Mini, requested by someone for racing in STR or something like that. There is zero expansion (ie any additional inputs or outputs) on this board.

 

Thanks for clarifying. I was not aware
