    Try the following settings and let me know GPS and speedo readings
    H0105 = 391.3
    H0136 = 391.3
    H0139 = 2556.1

    Forget about using the speedo calculator - it never works
    Where did the value in H0135 come from ?

    That was in the ROM when it was read as stock settings. I tired changing it to reflect the same pulses as in table H0101... Didnt seem to work. Secondly, I noticed another issue. In the The speedo calculator, on the VSS Pickup Teeth, it has 36... If you hit the drop down, 36 is not an option, it only gives you 17 or 40... Im wondering if the stock rom disassembly done by EFILive is incorrect. Like look at the stock rom I uploaded, and go into speedo and look at the crazy calculation that is in the stock rom with no modification to it. It states the tire size as 72" or 6 FT... I read that from the vehicle when I got it, so I had the theoretical stock rom that was on the truck before anything was touched. It makes no sense. I have been scouring the internet to see what the stock teeth count on the VSS Reluctor Ring is from GM to no avail.

    H0105 = 391.3

    Are these in Metric? I am in the states and have things set to imperial... A little slow on the conversion..lol

    I have no experience with 4wd, but it seems strange that H0152 and H0153 differ so widely

    Thanks, ya, lol, I was working it out...

    As to the 100.26 in table H0139, I tried varying that from 99 to 102 with no change on its own. As to tables H0105 and H0136 I was very curious about those numbers as well, but since the calculator did not change the H105, I figured it was good data. Doesn't going from 630 to 632 in the H0136 table make the tire smaller? In essence I think we need to make the tire larger, and I did try 626 in that table when I plugged in 32.10 as the calculated diameter from 285/45/22 tire size, it did not however change anything.

    I noticed this as well, and had not made my way to a question or hypothisis on that one either. Again, most tables where set based off of stock rom input, so if the calculator did not change it, I was reluctant to play with it...

    Also, its is a AWD setup, yes has a transfer case, but the transfer case is only 4 high, no adjustments like a normal T case.
