Description
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.
You may have a later Mk1 (1996/7) but if your car has TWO plugs that connect to the ECU then this is correct one for you.
See here for more details.
Every major and respected MX-5 Tuner in the UK, as well as the biggest, Flyin’ Miata in the US, recommends the ME Engine Management System over other systems.
Nick, Skuzzle Motorsport – review from MX5Nutz
“I have just spent the last few weeks playing with the fairly recently released Motorsport Electronics ME221 PNP ecu and finally after years of supplying, fitting, mapping MegaSquirt of all shapes and sizes, I am proud to announce that from this day on, my ECU of choice for most MX5 applications is now the ME221.”
It supports the 1.6 and 1.8 model from the same hardware, and also fits the OEM case, which means the ME442 installs tidily into the OEM position. 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 ME ECU Core (180Mhz 32-bit NXP Automotive Processing Power)
- Full replacement ECU board which supports all factory sensors.
- Truly Plug-In : Supports both switched TPS and linear TPS conversions.
- USB Connectivity
- 16×16 Fuel and Ignition Tables (with dual table switching)
- VE based fuelling algorithm.

- DSP Knock Control
- On-board 60psi MAP sensor (or use your factory AFM)
- Closed Loop Boost, Lambda, VVT and DSP Knock Control

“After trying a few better known brands such as Tilton and Extreme, and never being super happy... Conor was able to recommend me the perfect clutch for my application... I havn't broken any drivetrain parts since I installed it.”

Tell us the car. We will spec it.
Chassis codes, spring rates, angle kit clearances, clutch ratings. Send us the car and what you want it to do. The answer comes from someone who has run that setup, not someone reading a product sheet.

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
