    Hi, I am traveling from NY to Fla with a trailer and motorcycle behind my 08 Tacoma, with an Auto Trans.. I was told adding an "OBD monitor" would help me with shifting and gas mileage towing the the extra weight. Is this true? Does it just monitor how you are driving? Or can you add data such as extra weight etc. I have no clue

    Nope. A OBD monitor like the Scangauge and Ultragauge will only let you see info from your truck's sensors. It calculates MPG based on engine load and throttle position. It will help you drive better but they unit itself will not change anything on the truck. Search for info on those units. Lastly there are no OBD 2 plug in modules that will make changes to the stock ECU. Toyota encrypts their programming and they do not let just anyone mess with it unlike American brands.
