Coolant and air temperature sensors. The ME221 and MEITE software do offer the ability to calibrate the ECU to read any sensor, however by using the sensors on offer in this listing the standard calibration tables can be used - vastly simplifying the set-up process and saving considerable time. Both sensors are M12 x 1.5 thread. The additional coolant temperature sensor housing offers a quick and convenient method for installing directly into a radiator top hose and negates the need for tapping out existing holes in your cylinder head.
Crank Sensor. The ME221 ECU will work with the standard Zetec crank sensor. This sensor is therefore offered as a direct replacement and only required if you are unsure of your existing sensors condition or reliability.
Data Cable (FTDI USB-Serial Adaptor). Whilst the ECU comes with an RS232 cable many modern Laptops do not have such a connection. Therefore this adaptor will allow a USB port to be used for connectivity. This genuine FTDI cable is guaranteed to work with this ECU, unlike many cheaper alternatives that often suffer connectivity issues.
ALL ME221 and ME442 ECU's are shipped with a test map only. This is highly unlikely to run your engine and if it does it will not run it very well! A library of basemaps can be found here on the Motorsport Electronics Support Pages as well as a full suite of installation manuals. danST Engineering can also provide basemaps for a variety of engines developed on our in-house rolling road.
Coil Pack Compatibility
This ECU is intended for use with wasted spark Ford coil packs. Other wasted spark coil packs may be compatible however please contact us before attempting to use alternatives to avoid potential damage to the ECU. The fitment of a Ford coil pack (available in our shop) will guarantee compatibility and reliability.
Note: As with all after-market engine management systems (ECU’s) a dyno tuning is recommended to avoid damaging your engine and to get the most out of your engine. A full range of basemaps are available online from danST engineering or Motorsport Electronics.
