Hi All , Happy New Year 

i changed my Motor from carburerto to Injection but RPM not working 

any advice 

you need different dash as well as the proper wiring loom

 

It might be possible to fix this problem: if your engine runs normally with the injection. The dashboard takes a signal from one of the ignition coil terminals, I don't know which one, you need an electrician, but there will be a pin on the ECU connection,which gives a signal for rpm, and you should be able to join the two wires together, then hopefully the guage will work.
