The ME442 Gen2 Wire-In ECU is a feature rich and future proof injection engine management system. The ME442 builds on the ME221 by also having Drive-By-Wire and EGT for enhanced engine protection. Perfect for race-going 4/6/8 cylinder applications. Built from the ground up using the latest control strategies means a modern, powerful, VE-based ECU, with an enhanced feature set including closed loop boost, in-built Wideband Lambda Control, CAN, on-board data Logging and VVT control – all in a compact form factor. Massive IO means the ME442 Gen 2 can handle anything thrown at it, and custom tables mean any specific algorithms required can be easily derived.
The ECU comes with the main connector and terminals to build your own wiring harness.

Optional wideband lambda sensor kit (tick box at top of page + £125)
Genuine Bosch LSU 4.9 wideband lambda sensor for ME442 Plug-In ECUs including a harness for direct connection from the sensor connector to the ECU.
Optional 3 FTDI cable (tick box at top of page + £29)
A genuine FTDI cable for converting serial to USB connection for our range of ECUs.
This is not a Chinese clone, and will work correctly with our systems.
The drivers are available online.
Optional inlet temperature sensor (tick box at top of page + £29)
A Bosch/GM style 2-pin air temperature thermistor.
Uses a 2-pin mini-timer connector for wiring – the polarity doesn’t matter when wiring this sensor.
Features an M12x1.5 thread.
A typical calibration curve when using it with our ME221/ME442 ECUs is shown below:
Optional 3 Bar MAP sensor (tick box at top of page + £40)
This is a Cosworth style 3-Bar MAP sensor, used for measuring manifold pressure. Capable of reading up to 2-bar (30psi) of boost.
It uses a 3mm barb for the vacuum line fitting, and a 3-pin mini timer connector for electrical connection.
The pin-out is:
VREF (5V)
Ground (Middle Pin)
Signal Out (pin closest to the brass eyelet)
The typical HRT calibration you would use in the ME221/ME442 is pictured below:
