The ME221 MX-5 is the latest plug-in Engine Management System for the Mk1 (3 Plug NA) MX-5 / Miata, years 1996-1998 1.6/1.8
**This is the “3 Plug” Mk1 ECU. Check if your stock ECU has 2 or 3 Plugs before ordering if you have a later Mk1. If it is 2 plugs, then you need the 8995 version**
This convenient plug-in ECU is designed to replace the original circuit board within the casing of the vehicle's factory ECU. The ECU retains the original connector, allowing for a straightforward installation process. The OEM ECU casing provides protection and ensures a clean, factory-like appearance. By fitting inside the original casing and utilising the original connector, the ECU offers a discreet and efficient way to upgrade the engine's control system.
With this type of plug-in ECU, you can enjoy the benefits of enhanced engine performance and customisation without needing to modify the wiring harness or perform extensive rewiring while maintaining full OEM functionality!
It supports the 1.6 and 1.8 model from the same hardware, the only extra thing you need to do besides plugging it in is run a MAP vacuum hose (supplied) from the ECU to the intake manifold.
