INSTALL VIDEO GUIDES

OEM Idle Control

Utilises the stock idle/cold start valve to give excellent idle and warm up air control. Will also ramp idle to support AC and high-load cooling fans to start smoothly.

OEM Connectivity

Because our Plug-In systems are designed on OEM cars, they offer true PnP install, utilising many of the factory sensors. They also retain OEM control of things like the factory dashboard, Hi/Lo boost switch, Distriubtor (can be upgraded to COPs), Idle Air Control, Air-Conditioning and other functionality.

Go Coil-On-Plug

The classic distributor as used on the Toyota can be a thing of the past. No longer a concern, you can choose to upgrade to a coil-on-plug setup to give support for higher boost levels, longer dwell times and more accurate ignition. Don’t let a rotor arm hold you back to realising your power goals!

Knock Protection

The ME221’s advanced knock control offers true DSP processed measurement of knock, with per-cylinder angular windowing to locate, and act upon signs of knock, ensuring engine safety and longevity. Fuel enrichment, ignition retard and user definable aggressiveness give maximum control.

Basemaps

Having rolling road facilities in-house means we are able to offer ME Certified basemaps for an array of different configurations. This means along with a straightforward physical install, you can be up and running in minutes – ready to shake the car down prior to professional tuning on a rolling road.

1st Class Support

It might be simple to install, and even easy to tune, but that doesn’t mean that help isn’t on hand when you need it. With a network of approved tuning shops across the UK & beyond, UK telephone support and an ever growing online community means you will never be left in the dark. The ME experience is more than just a box of electronics…

VE Based Fuelling

Accurate, modern VE based modelling of the engine means faster to tune, and more accurate compensations for environmental changes as opposed to older pulse-width based management systems. Microsecond accuracy with fuel and ignition calculations carried out over 500 times a second means unparalleled transient response and consistent results.

Powerful Tuning Software

The Motorsport Electronics Integrated Tuning Environment, or MEITE, for short, is a powerful, flexible Windows tuning interface for working with our range of ECUs. Fully customizable layouts and interface, allowing the novice to play with just the basics (starting from one of our many base-maps), or the advanced tuner to really get under the hood, the options are there…

Powered by ME221

Because all of our Plug-In range share the same core, it means the full feature set is available regardless of the model you choose – and this also means better familiarity with the system for tuners and installers.

Boost Control

Fully featured closed and open loop boost control means accurate manifold pressures and turbo waste-gate management – several dimensions of control including throttle, rpm and even gear based boost targets. Quicker spooling and stable boost means optimised torque can be delivered under all conditions.

Motorsport

Switchable maps, Launch Control, 2-Step Limiters, Water Injection, Flex Fuel & Anti-Lag are just a few of the advanced features of the ME221 core – all included, all unlocked. And with more features added over time via free, in-field firmware updates, the list is ever growing…

Custom Functions

With general purpose tables and custom variables, you can combine inputs and effectors to create practically any bespoke function you may require, all from within the MEITE tuning software.

SUPPORTED MODELS

  • Starlet EP82

  • Glanza EP91

Worldwide Tuner Network

We have over 100 authorised tuners across the planet, and the list is constantly growing – meaning you’re never far away from a tuning professional who has experience of the ME221 and will therefor get the best from your engine. That being said, any competent rolling road tuner will be able to use the MEITE software to tune the VE and ignition tables, and we are always on hand for further support if required on the day. Want to know where to find them? See the map here.
