: How do I recalibrate my Speedo and DIC for different tire sizes? mwaa_katn 10-07-2007, 07:21 AM You should be able to go get it reprogrammed at the dealer. If that don't work you could buy a programmer to do this. I know that Superchips is offering a tire calibration in thier new flashpak programmer. I am sure there are more out there on the market. Tom S. 10-07-2007, 07:34 AM Dealer can/will only re-program up to a certain size, 265 I think. After that, you'll need a programmer (like diablo, etc.) to do it. GMC-2002-Dmax 10-07-2007, 08:55 AM For the Speedo a simple change to the VSS pulses is done, if you go to a very large tire the module needs to be altered with a TECH II that stores the ABS info. That will help the ABS work better. ;) | ||
