I wish I could help but my speedo reads in KM/H so anything I do would be of no help at all. In fact I think of all of my gauges in the Pantera as approximations of values. Kind of friendly suggestions but in no way accurate indicators of actual conditions. All except for my clock which has been dead nuts accurate from the day I got it. It is the single most amazing piece of equipment on my car. If my whole car was up to the standards of my clock, everyone on this forum would be jealous of me.
