Since the introduction of OBD-II in 1996, companies have been offering up the hardware and software needed to tune your 4x4’s engine for more performance right at home. Edge Products has released the new Evolution CS and CTS units, short for Color Screen and Color Touch Screen, respectively.
The Edge CTS unit is available for both gas and diesel. Upon first plugging the unit into your OBD-II port, you will be prompted to select a make. Then the unit reads your model from the vehicle’s VIN and assigns the proper tuning options.
The CTS is an in-cab display unit that has a full-color, high-resolution, 4.3-inch touch screen. The CTS has the ability to display up to eight vehicle parameters at a time, has a light meter that automatically dims the screen as the ambient light decreases, has the ability to read and clear trouble codes, and even does performance testing such as 0-60 and quarter-mile times.
By manipulating the fuel injection map, timing curve, and many other parameters in a stock 4x4, a quality custom tune can do wonders for your not-so-stock 4x4. Because the standard tunes from Edge are geared toward stock vehicles, we contacted Bill Cohron of Power Hungry Performance to write us a custom tune for our Ford F-150. Cohron comes recommended by Edge for custom-tuning Ford vehicles. He was able to write us a Performance tune that utilizes 87-octane gasoline instead of the 91-octane tune that the Edge unit ships with, along with a nice towing tune.
