Anybody know where I can go or what product I can get to have my truck recalibrated for the larger size tires. With the 35's everything is out of whack especially the ABS. That's what I'm most worried about.


Thanks


Rich.

Thanks Brian

I'm actually not too far from you. I'm in Riverbank (next to Modesto). I go to Pismo every once in a while usually just to tune my drag quad. How about you.


Rich.

yeah we go to pismo all the time....went to dumont for the 1st time presidents weekend....makes pismo seem like a sandbox

As far as I know right now the only way you can adjust the ECM for different tires size is to get an ECM from steve cole at www.ttspowersystems.com (http://www.ttspowersystems.com) There are no other programmers available to do this yet.

The Speed Cal (Tire Rev Per Mile) is part of the Main ECU cal and only GM Engineering has the tools to recall it. You would need to know someone to "Build" you a new Cal.


Then


If you can find a dealer to do it, The TECH II can be used to update the Tire size for the ABS ECU.
