How to display speed readings on skyline r34 dashboard? The thing is that the ecumaster black generates a rectangular 12v signal, but the dashboard only accepts a high voltage 50-60v sawtooth signal
The factory speed sensor is in the transmission, I replaced the transmission with a cd009.
I took the VSS speed readings from the abs sensor and put it on the adu dashboard. But I don’t know how to display the speed on the native dashboard.
