Is the signal wire from the computer to the factory tach sending a voltage signal or a frequency signal? If its voltage, does anyone happen to have some sort of chart that shows voltage vs. rpm? I thought of a little side project today, and need to aquire a voltage signal for rpms. I have an old tach that I could tear apart to get the converter, if anyone has any experience on this, help would be appreciated! Thanks!:thumb:
