Speedometer programming
A followup on the speedometer: Mine was set for "10" (2+8), and the factory
called for 26 - switches 2,3 and 6 which are 2+4+20. I set that, and it still read substantially high. I set 40 (switch 7 only) and the speedometer was about 20% low. Set 34 (switches 3, 5, 6, which is 4+10+20), and I was 5% low, then 32 (switches 2, 5, 6) and I was essentially dead on. This was done over a trip of 150 miles today, and during it I also set my digital VMSpc speedometer to dead on - it was 1.8% fast over 10 miles of flat desert at exactly 60mph. I now have two accurate speedometers, analog and digital. From this I conclude that the dip switches are additive, as shown above, and the higher the combined number the more they take off the speed. In the various invoices I have with this coach are two for transmission ECU replacements, with the symptom being initially a lack of any speedometer reading at all, and the second a couple of days later when the "new" replacement failed completely. The shop which replaced both (second under warranty, of course) noted that they could not get a second identical one either new or reman, so used a reman "+2" unit. I don't know what that means, but I assume it is somehow different, and probably doesn't put out the same speed data as the original, which is why factory programming didn't work.
