My Miata runs on Speeduino/SpeedyEFI

And it is, so far, a fantastic little ECU. Tuning is simple, especially with the AutoTune feature on TunerStudio, even with a narrowband O2 sensor.

Fairly certain this ECU will give MicroSquirt a run for its money in terms of cost. Sure, it may not have the foundation that DIYAutoTune has with MS2/3, but at twice the cost not including accessories that are available, it’s incredibly worth it.
