FYI all motronic 1.1/1.3 55 pin ECU's have the same pinout, including the seta and M30s.

on that i found the mating face with the numbers but nothing telling me what the numbers are

The ETM does. it tells you every single pin. start with the block diagram.

Yep, it's all there. I want to say even bentley has it.

So, I have to go through all the pages and find each pin? There isn't a chart somewhere with the connector and what all the numbers are/do?

[nando]

look in the BLOCK DIAGRAM.

;)

Ok, I got a lot of them but i can't find pins 9, 11, 15, 20, 21, 25, 27, 30, 33, 34, 35, 38, 43, 44, 46, 49, 50, 51, and 54.

not all of the pins have a function, they are just spares.

[85Dirty30]

well ya i figured that, but i feel like that's a lot of unused pins

[nando]

off the top of my head, I don't recall any of those doing anything.

what are you using it for, btw?

[85Dirty30]

well I got 15

[85Dirty30]

well being there is not a diagram telling all the pins and what they do, I would make one. All i really need is tach, O2, Tps, knock, and the air flow input

[Jean]

Here you go

[nando]

there is no knock input
