  • 7" Digital Dash Odometer

    I've had a driveshaft sensor since V4 EFI software days. It consists of an eight magnet ring on the pinion yolk and an MSD Hall-Effect pickup. Has always been reliable. I use Input # 4 driveshaft speed for speedometer displayed on the Digital Dash. I was also able to configure an odometer which worked great until V6 EFI software came out. Haven't had an odometer since then. I have it configured on the Digital Dash, but it doesn't advance. I'm now thinking maybe I need to split the driveshaft signal and send Driveshaft speed to a Digital Dash Input.

    Check your odometer programming to see if it changed: https://forums.holley.com/forum/holl...974#post364974 (Related Forum Thread)

      I have "ECU Input" and Input # 4 (Driveshaft Speed) selected. Now the odometer is displaying wheel speed in MPH. If I have ECU Input selected, what Input is it looking for? By the way, I have an HP ECU and all I/Os are in use. Do I need to split the driveshaft sensor output and connect to the Digital Dash harness and do it that way?

        No, you shouldn't have to do that.

          Possible I may have missed something, but I've read all of that and don't see where it applies to a driveshaft sensor Input. This is how I have Input # 4 configured:

            Got it working. I resisted as long as I could then finally changed Input # 4 from DS Speed to SPEED, cycled power. So I guess when you configure a gauge and name it Odometer, it's automatically looking for SPEED.
