The ME442 MX-5 Plug-In is our latest Engine Management System for the Mk1 (2 Plug NA) MX-5 / Miata, years 1989-1995 1.6/1.8. This package includes the Wideband Sensor and Cable.
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.
Along with the standard ME221 feature set, the ME442 version adds the following features:
On-board Bosch Wideband Lambda O2 Controller
On-board Real-Time-Clock and SD Card Data Logging
Drive-by-Wire Support (some models, please enquire if needed)
K-Type EGT Input
Accelerometer and Gyroscope
CAN Bus for external dashboards and expandability
The core has as standard:
Uses the ME221 ECU Core (NXP Automotive Processing Power)
Supports factory sensors.
Truly Plug-In : Supports both switched TPS and linear TPS conversions.
16×16 Fuel and Ignition Tables (with dual table switching)
VE based fuelling algorithm.
Run any type of high impedance injectors.
DSP Knock Control
In-built 60psi MAP sensor
Closed Loop Boost, Lambda and Idle Control
Launch Control
Fully Sequential on 1.8 version
In the field regular firmware updates and improvements
Uses the powerful MEITE tuning studio.
An open approach to firmware/software features.
Supplied with rolling road certified and developed basemaps for either turbo or NA setups.
Please note that if you are using a switched type TPS sensor as fitted to the 1.6 model, we suggest installing a variable TPS to give better throttle response – the 1.8 model already has the variable TPS as standard. Also, if you wish to run without a MAF sensor, then you will need to install an Intake Air Temperature Sensor – available in the options list.
