I just want to revive this one to see if anyone has got it to work on a Super Duty. I only have one button on the gauges so I don't see how this will work.
Been meaning to get back with ya'll on the issue. It only works on the OBS trucks. The ABS module can be re-flashed up to 6 times, on the SD's, to get it as close to the correct speed as possible. I've found a good deal on the TruSpeed product, so I think I'm just going to go with that set-up.
