Audi a3 1998
 

I am thinking about ordering a mpguino as i don't have a trip computer.
All my efforts to visualize real time consumption were too much complicated for real life use... I connected a vag com cable to a computer, then sen't singal to a multimedia radio via a avermedia Vga to video converter, all this with the electrical adaptations due to voltage of different devices...

Now it is time to make it simpler

I have many questions

BUt lets begin with 2

can i get L/100km measure?
Where is VSS and injection on my audi?

Who knows maybe somebody can help

THank you a lot, i admire all i have read from you!
great web!

I have found a pinout for the ecu
Bosch ME 7.5 ECU

i doubt if i should connect to it directly..i think i have to look for the wires located on the harness.. if i find it!

according to that
vcc is pin 2
and injection is 22
right?

by the way don't iso audio connectors to radio systems have a vss wire?
then i would need to get the injection cable only, where is injection plug in the motor? i should tap the one without 12v...

The audi a3 has a vss wire to the radio system. That is what I know..
