So I built a DIYPNP Megasquirt ECU (INB4 hipstergram)
Flashed it with firmware
Installed it in my Miata
Which has this engine
Made this custom dashboard in Tunerstudio to monitor all my functions
And now I could spend literally all of my time driving around and tuning my car... Having 100% control over the mechanical symphony and its various sensors is crazy. Tuning a carbureted engine is my roots (and I'm not any good at it) but when you can build your own ECU and tune it so that your car starts and runs in any condition 100% better than it did when stock is crazy. I love putting it in 3rd gear and flooring it from 1000 RPM up to the rev limiter and watching the air-fuel ratios be perfect with no chugging, bucking, pinging or hiccups.
Just wanted to share. My thanks to all the great people out there that have developed this system so that people like me can have control over their cars. If you've never installed Megasquirt in a car, you've really got to try it. It's not as hard as you think thanks to the designers who have made it easy!
