zdude1967 Posted May 8, 2017 Share #1 Posted May 8, 2017 I recently installed the Crane xr3000 and used the 14 gauge wire - per the Crane instructions. However my tach is not steady and it will drop sometimes between shifts. It just generally works poorly. I have heard of a fix for this - anyone know what it is.

Chickenman Posted May 15, 2017 Share #2 Posted May 15, 2017 What year is your Z? Early 240Z cars have a Current sensing Tach and thye don't play nice with aftermarket Ignition systems. . Several options available depending on what year your car is.
