Hello, it's possible to make original S4 2001 tacho work with VEMS ? I have wire from ECU to external tachometer (from AutoGauge) i didn't tested because engine removed... The problem is that on VDO cluster don't know which one is for tachometer. And in my opinion it's not just connecting wires, am i right ? VemsTune showing revs, but original tachometer not. A bit weird, than only speed on cluster working...
