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 and fuel and ignition calculations carried out over 500 times a second means unparalleled transient response and consistent results.

Idle Control

PID Closed Loop Stepper based, DBW or PWM Idle control with idle up on demand from other systems such as AC and cooling fans means OEM-like starting, warm-up and drive-ability. Spark-Scatter means even faster idle response by varying the ignition advance to compensate for slight load variations.

CANbus Connectivity

With CAN-Bus, you can connect other devices such as dashboards, EGT modules or power control systems directly to the ME442, expanding its control and data capture with the simplicity of a 2-wire, vehicle wide network.

VVT Control

The ME442 comes equipped with full closed loop mappable VVT control. From the simple on/off system such as Honda V-TEC, through to the continuously variable system as used by the Ford ST170 & BMW VANOS engines. Optimised camshaft timing helps to deliver a smoother, higher torque curve across the rev-range.

Massive I/O

Inputs & outputs can have an array of different functions assigned, meaning unused injector channels could instead be used for boost control, or the spare O2 signal could be used for a Flex Fuel sensor. With 90 pins for connectivity, and over 60 channels of IO, including 38 Outputs, 12 Analog and 8 Digital inputs means even the most complex engines can be controlled and monitored with the ME442.

Knock Protection

The ME442’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.

Fault Diagnosis

Using the latest Bosch ASICs for outputs, the ME442 actively monitors for short, open circuit and over current conditions on the injectors and coil drivers – making it easier to track down wiring faults, or protecting against hardware failure and connection errors.

On-board Logging

With 4GB of non-volatile on-board memory, the ME442 will log over 200 channels at over 100Hz for more than an entire Le Mans 24 hour session!

Wideband Lambda Built-In

The ME442 features a BOSCH LSU4.9 Wideband controller built in for accurate, fast measurement of exhaust gasses to determine the engine’s Air/Fuel Ratio. Coupled with closed loop control, the ECU will target the correct fuelling, or, populate its Long Term Trim table to show errors and adjustments made automatically in real time to the VE table. Even better, when connected with MEITE you can use auto-tune and let the ECU do the hard work of tuning the VE table to perfection.

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 Features

Switchable maps, Launch Control, 2-Step Limiters, Water Injection, Flex Fuel & Anti-Lag are just a few of the advanced features of the ME442 – 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.

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…

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 ME442 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.
