ME221 MX-5 Plug-In ECU, the leading Engine Management System designed specifically for all NA/NB models from 1989-2005. This innovative plug-and-play unit by Motorsport Electronics seamlessly integrates into your vehicle, replacing the original circuit board within the factory ECU casing.
- Seamless Integration: Retains the original connector for a straightforward, no-fuss installation. Fits perfectly inside the OEM casing for a clean, factory-like appearance.
- Enhanced Performance: Enjoy improved engine performance and customization without the need for extensive rewiring or modifying the wiring harness.
- Wide Compatibility: Supports both 1.6 and 1.8 models using the same hardware, ensuring a tidy installation in the OEM position.
- Comprehensive Sensor Support: Compatible with factory sensors, and includes additional features like DSP Knock Control, a built-in 60psi MAP sensor, and more.
- Advanced Fuel and Ignition Control: Features 16×16 Fuel and Ignition Tables with dual table switching, VE-based fueling algorithm, and the ability to run any type of high impedance injectors.
- Cutting-Edge Functionality: Offers closed-loop boost, lambda, and idle control, launch control, and fully sequential operation on 1.8 versions.
- User-Friendly Tuning: Comes with the powerful MEITE tuning studio, allowing for easy adjustments and regular firmware updates and improvements.
- Pre-Configured Basemaps: Supplied with rolling road certified and developed basemaps for both turbo and NA setups.
Additional Notes:
- If you are using a switched-type TPS sensor (fitted to the 1.6 model), it is recommended to install a variable TPS for improved throttle response. The 1.8 model already includes a variable TPS as standard.
- To run without a MAF sensor, an Intake Air Temperature Sensor is required, available in the options list.
Upgrade your MX-5/Miata with the ME221 MX-5 Plug-In ECU and experience the pinnacle of engine management technology. Enjoy enhanced performance, easy installation, and the reliability of Motorsport Electronics’ cutting-edge design.
