converting a vr6 tacho signal to display on 16v rev counter

[spanneredmonkey 0]

I have asked before but cant find the thread, after some googling, I understand there is a mod you can do, I have a a coil pack vr6 lump in my 2.0 16v shell, the rev counter is reading way high mostly i belive to it seeing 6 sparks per cycle rather than 4, is there any way of converting the signal ( i have read about a variable resitor under a cover) without having to replace the whole cluster, My car has only 80k on it and have full history with it

VR6 tacho counts 3 pulses, 16V counts 2.

 

Your best bet would be to use a generic rpm generator. I can't remember the brand but Stealth Racing sell them. You just tap into the coil signal wire for cyl 1 and the rpm box does the rest. The output of which you send to your clocks. I think there's dipswitches on it to set the signal count for a 4 or 6 cyl. Stealth will know more. A few of us have used them successfully on R32 conversions where the original clocks use CAN BUS for the rpm signal.

Seems like a bit of a bodge, but the I think the method you describe is detailed here;
