In my mind, I just seems more correct to make the ECM recognize the correct gear ratio first, and then correct the pulses per mile. Perhaps this won't work on all trucks, it has always worked for me, but more and more it seems like these damn trucks are very tempermental, and have each got a personality of their own. LOL!
Interesting note however, at least on a snap-on scan tool, it does read 4 independent wheel speeds...however I don't recall weather or not the 2 rear wheelspeeds read identical all the time or not. Makes sense they would have to being as the only speed sensor for the rear wheels is on the transfer case.
