Tachometer not working
 

Hi.

I have a -96 mx5 1.6 with mspnp 9093, zeitronix wideband an a greddy kit.
My tacho dosn't work. The former owner says i had been working. In Tunerstudio it's showing, but not in my meter on dash. Have tried with another meter. Still no rpm showing. Also have been reading hours on the net, but only tip I get is the resistor. I don't think that is the problem here. Because it has been working earlier.
Anybody have some tips for me? I'm going crazy...
Thanks.

The tachometer is not ecu driven. It's driven by the ignitor.

Ok.
Does that mean it has been drawn an ekstra lead from ign to ms? It is not me that has mounted the parts om my car. It was the former owner.
