I've got a silver HKS turbo timer type 1. I've connected the speed and rpm wire to the ecu. The speed shows up on the timer. But not the rpm. Nada. I remember it said something about a digital signal in the instalation manual and a part needed??

are you sure you have connected the rpm signal to the correct wire on the ECU,id double check you have wired in to the correct PIN

 

ask chris @getGReddy in the traders section,he sells turbo timers etc,so may be able to help if something else is needed
