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.Last edited by 3db; 6 September 2016, 21:43.
