Currently the only tested configuration is the NA6 Miata with a manual transmission. If you have a different car, we may need your help testing the configuration! Automatic transmission cars are not yet confirmed to work, although there's no reason to think they won't. Currently the only tested configuration is the NA6 Miata with a manual transmission.

The standard configuration runs the engine using the stock AFM (Air Flow Meter) to measure engine load. However, the AFM on early Miatas is an actual restriction in the intake and costs possibly as much as 3hp (this is a guess). It's also useless if you want to add boost to the car- the capability to measure airflow peters out well below the airflow capabilities of even a mild turbo or SC setup.
