The ECU Input must be named "Speed" and the units set to miles/hour for the odometer to report distance accurately. If you're using a custom VSS Input directly connected into the Digital Dash IO3 or IO4 pins, and/or need an Odometer: http://documents.holley.com/199r10746rev1.pdf (Holley 553-106 Digital Dash Instructions - "Vehicle Tab" & "Dash Speed", Page 11) Go to Menu, Configuration, Dash Configuration, Vehicle Tab, and change Speed Input to "Dash Speed" (LINK). This is the only setting that requires you to enter values in the Local Dash Speed Calculation fields on the Digital Dash. |

HP ECU is only compatible with Hall-Effect type VSS. http://forums.holley.com/showthread....2656#post82656 (Speedometer/VSS Information - Read posts #2, Groups & #6.) Are you trying to send a PPM (pulses per mile) signal to a speedometer, or adding a vehicle speed sensor channel input? If operating an electronic speedometer, do so by using the "Speedometer Output Enable" in the Transmission ICF: http://forums.holley.com/showthread....0291#post30291 (Speedometer Output Info - Dominator ECU/Transmission ICF) If wiring a stand-alone VSS sensor (MPH display), do so with a custom speed Input in the Inputs/Outputs ICF: http://forums.holley.com/showthread....ith-Holley-EFI (Installing A VSS Sensor) |
