Marco,
I know that you responded with my question about the ABS tire size change previously and said the Smarty did not change stock setting when put back to stock.
This is a sequence of events that occured and the result. I sort of understand why, but it does mean that I will have to pay the dealer to program my ABS for a tire size change a second time.
My truck was programmed by the dealer for my BFG 315s, ABS RPM set to 605 before any Smarty load.
Loaded the Smarty a few times and returned to stock.
Change tires to BFG 285. Loaded the Smarty and attempted to change tire size. Don't think the ABS setting really changed, but it did read the ABS setting from ECM(605).
I unloaded the Smarty and went to the dealer and had the ABS RPM set to 636 for the BFG 285s. I wanted the tire size correct with or without the Smarty loaded. The change was correct confirmed by rpm/mph and distance.
Loaded the Smarty and things were still correct for the tire size based on rpm/mph.
Unloaded the Smarty and the original setting for BFG 315s was put back in ABS RPM(605).
This seems to be a sequence of loads and ABS reading that set the stock size to 605 and since I did not do a ABS read before returning to stock after the ABS RPM change.
Now I will put back to stock and have the dealer reprogram for the 285s. I will then load the Smarty and do a ABS read and hopefully that will note the correct ABS RPM value and reset it that way when I go back to stock.
This is just a heads up and I think can be recreated with the same sequence of events.
