I assume he's talking about MSA12/MSA15 TDi 68pin ECU. Yes, pin 9 is the consumption signal. In Audi 80 it's left unconnected. Go directly to the ECU, it's behind heating box in passenger's footwell. Signal output is square wave with varied pulse width and frequency.

And yes, it is possible to install OEM board computer in Audi 80 TDi's. You just have to have a 68pin ECU or install one, if you have older one. I have made adapter for the consumption signal, at least 4 cars including mine in Latvia is using it with no problems.

What signal comes from the ECU ? I'm trying to make a BC with arduino and this would be very helpful. Where does this Pin 9 from ECU go? Can I find it in some socket under the dash?

What ECU are you talking about? ABY ECU Pin T55/9 is the connection to the F96 Barometric pressure sensor. The fuel consumption signal is in pin T55/31.

Thank you!!

Swap over that big white part from V6 cluster to your 7A.

[mihai_antony]

ok
in order to be sure, I need to move the bord computer from V6 to the 7A instrument cluster, in order to use the 7A fuel, water, acc instruments

correct?

Yes you can. Swap over computer unit to your existing cluster and it will work correctly.

Hello

I can use a V6 bord computer and Autocheck with a 7A 20V engine?
There will be errors on the consumption or fuel indicators?

Thank you!

You have to know something about electronical systems in no is possibility to broken something

[Marius]

why?

[shellah]

hmmm... I think it" waste of time ...

[Marius]

does anyone tryed to use this idea from "audifieber"?

[Marius]

you owe me a drink

Sküll, if you look to mine #33 post, you will see same link.

share the drink

you mean, 1z with ECU "028 906 021C"? I think the difference just between ECU (if we talking about putting BC).

my 94 b4 tdi 1z with that one unit.
