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:
