Dramier Posted June 25, 2005 Share Posted June 25, 2005 I accidently discovered the Z31 digital dash setup includes a 2.2K ohm resistor from the factory for the tachometer to function. Low and behold, this same resistor also allows my aftermarket tach to work with my RB25DET ECU. Just thought some of you might find this bit of information useful.
