Audi consumption display

[max]

Hello.
As far as I know VEMS does not support trip computer that shows info with consumption info etc etc but yesterday I saw a swapable gauge on VemsMT that says "consumption" l/100km. So I was wondering if there is any chance to make this thing work? I know that it will not show 100% correct consumption but I just like to see something happening on that trip computer than just showing "0" :) basicly motronic has only one signal wire to dash-board IIRC.

Motronic will be putting out a square wave signal based on pulsewidth. Dashboard calculates consumption based on road speed and engine rpm.

There isn´t a specific channel for fuel consumption. But you could output a boost signal to that gauge so you could see boost perhaps.

Ok thanks.. so seems that its no impossible currently  :-\

or try to connect one injector, but with resistor and zener diode(becouse flyback voltage is to high for that input).
