Car had an engine fire in 2020 and burned up some of the harness. I know some things got shorted (for example the car was cranking over with the key out until I disconnected the battery.) A couple things melted, but apart from the wiring harness it wasn't that bad. At the time I was still in school though and ended up selling it a year later. Fast forward 3 years and I see it up for sale and buy it back. The guy ended swapping a 95 miata into my chassis. Engine, transmission, wiring, ecu, etc. is all stock 95 miata now, with the exception of my dashboard and suspension.

I got the old MSLabs MS3 mini that I was running in the car which is what I am interested in salvaging. I haven't taken it apart yet but at a glance the board looks okay. I can add photos later of the board and everything. I'd rather not get a JimStim from DIYautotune and painstakingly wire everything up and test each input/output. Is there any risk to plugging it into the car loading a basemap and starting it?

 

I don't see any problem.

I finally got around to trying the megasquirt last night in the car, and was able to get it to fire up and idle on the narrow band. Seems everything is still functional.
