what good is this thing again?

[wazmoenaree]

Besides causing my ABS to stop working - fixed and Idle surge. What is this thing good for?. It doesn't read trans temp,psi or fault codes. It will reset them which
helped when the thing generated a chek sum freekin error. I hoped to use it to monitor my 2-3 and 3-4 trans glide issue, but it made to many of its own. I did
detect a slight change in power with performance, tow- not!.
It also only lets me change redline/top speed and loosely idle speed with the cruise buttons.

The question is - does it monitor trans temp and psi?
It is possible that my PCM is mental but so far it works better than the sport.

You should feel the performance gains for sure, if not, i would question if the truck is not healthy.

trans temp is not something the tool can monitor, the tranny uses a separate controller.
