is it a TACH problem, or an engine problem? If you messed with the tach, such as taking the needle off, fiddling with it, it's a lot more complicated to get it calibrated. If it's an engine problem, you will most surely find your answers here. www.240sx.org

It's an easy fix

, what year is the usdm guage cluster from? What i'm about to tell is all that I've gathered from online sources, take them however you want to. I've made my usdm DOHC HUD gauge cluster work with my SR tach. You need to get the DOHC gauge cluster, then swap the sr tach into the usdm gauge cluster, then it'll work. Requires a little cutting on the sr tach.
