ECUMaster EMU Black pinout sheet
A printable sheet with every pin, made from the checked data on this page.
Where this comes from
Only ECUMaster's own documents. Pin names and notes are written exactly as ECUMaster writes them.
ECUMaster pinout for this ECU
How we checked it
- We start from ECUMaster's pinout document for this ECU.
- Every pin is read again in a second ECUMaster document: the compact pinout sheet, the user manual or, for pins that are the same on a sister ECU, that ECU's pinout. Where no second document lists a pin, we read it a second time by eye from the same pinout.
- A pin is only shown when both readings give the same function. ECUMaster's documents name no wire colours, so none are shown.
- Notes are ECUMaster's own descriptions from its pinout.
