Notes:
For the ZR family, we make the following recommendations:

1. The 440 must be wired into the factory loom. External components required are a loom (short or long, depending on application) – loads for the factory ECU and an OBD interface to avoid fault codes / engine check light appearing.
2. If you’re doing your own tuning, we recommend adding a wideband lambda sensor.
3. In this sort of application, we would suggest controlling the fuel and ignition with the aftermarket ECU, and allow the factory ECU to communicate with the instruments, control the electronic throttle and the anti-pollution gear. This is generally how an aftermarket ECU is wired into a modern car.

Also see lower cost option, e420d. The functions you lose with the e420d, compared to the e440d, are:
1. No flex fuel function.
2. No adaptive tuning function.
