please excuse my ignorance but I am trying to get my speedo working through the Cable X converter I am using. The LS3 and ECU came from an auto and I have a T56. The VSS sender is connected to the ECU and I am trying to pick up the signal for the Cable X from the ECU. The speedo isn't working and I ran a scan and noted the speedo display maxed out at 255km/h (with the car stationary). I made an inquiry with the harness supplier who advised it was a tune setting. He kindly advised what the settings should be however I am unable to see the pulses per mile option in my tune. The speedo menu item only discloses tire rev per mile. I am looking for the settings as depicted in the attachment (which don't appear in my tune). Any help is appreciated.
