Development Process

As mentioned before, the DCL Protocol is no publicly documented protocol. Therefore developing this board was a big challenge. Most information to start with comes from this project: https://github.com/babroval/ford-eec-iv-diagnostic

It was way easier to buy a cheap EEC IV ECU and develop with this, then testing everything against my car. IMG_20221230_190347
