How we checked it
- We start from MoTeC's datasheet for this ECU.
- We read every pin again on MoTeC's product page for the ECU, and in its hardware manual where that covers the ECU. A script compares them, pin by pin.
- A pin is only shown when its pin name and full name match in every document. MoTeC sets no standard wire colours, so none are shown.
- The notes are MoTeC's own words, shown when two of its documents print them alike.
