Show original supplier description
The SpeedyEFI NA6PNP is a comprehensive and user-friendly kit for upgrading your 1990-1993 Miata to full standalone engine management. The complete package includes the Speeduino NA6 pnp ECU, a MAF/AFM delete plug, a GM Intake Air Temperature (IAT) sensor, and 8 feet of map line. It also comes with a BMW vTPS (throttle position sensor) and a dedicated harness to connect it to your vehicle's stock TPS plug. Customers can choose between a standard 3D printed TPS adapter or an optional upgrade to a 6061 aluminum adapter for enhanced durability. This kit is specifically designed for the 1.6L NA6 models of the Mazda Miata, utilizing the 48-pin ECU found in these vehicles. Users will need to connect to their ECU using Tunerstudio software for calibration and configuration, including potential adjustments for sensors like the barometric pressure sensor and idle control. SpeedyEFI typically restocks these kits on Mondays. Installation guides and wiring information are available through SpeedyEFI's blog and the Speeduino wiki, with community support also accessible via forums and YouTube tutorials.
