I was working with Jeff @ Whipple with a serious bug in the Tomahawk programmer.
If you want to change your tire or axle size to correct the speedo, then you will get the trusty Wrench icon and a 4WD/AWD powertrain fault.
I attempted to change the settings for my 37s and while it did correct the speedo I couldn't get the Wrench light to turn off.
Changing back to stock sizes worked.
Jeff knows about this and they will hopefully provide a fix soon.. just an FYI.
We had an issue with a P0061A and we resolved that so we'll get to the bottom of it. The speed info is now in multiple modules which makes it more complicated, but the Tomahawk can flash any module in the vehicle.
