Audi 80 B4 1,9 TDI ECU pinout
 

Does anyone know where it's possible to find out the Engine Control Unit
pinout?

I want to install the onboard computer for my car and I need to know which
pin is the fuel consumption pin. And is it anyway possible to install the
onboard computer?

My car is Audi 80 B4 1,9 TDI (1z engine) '1994

Hi!

Take that with a grain of salt, it's HIGLY speculative:
My schematics show no connection from ECU to the BC on
the B4 model *But*: The schematics for the C4 (with 1Z engine)
show a connection similar to the fuel consumtion pins for other
ECUs (Motronic, Digifant, etc.)

Measure pin 9 of the 1Z ECU for a meaningfull signal. Check
Connector T5/3 (5-pin/black under drivers panel, yellow cable)

HTH
So long!

Hi,
first of all sorry for my bad english! I looked for manual about "how to read off the ecu" and found your posting!

If you´re looking actually for a solution check this site WorldWideWeb.meckisfaq.de/viewtopic.php?t=345&highlight=diesel (Sorry, it wasn´t allow to post the complete link! please change WorldWideWeb into www)

Problem should be that the 1Z hasn´t a fuel consumption pin! You need do generate this signal for your onboard unit!By the way in germany they call it BC or BordComputer!

I hope I could help you! Sorry for my late answer! Greetings from Germany!
