Flash Programmer: Re-Flash the Onboard Computer To finish off the fuel-efficiency upgrade for this vehicle, the truck's on-board computer is re-flashed using a flash tuner system, customizing it to the upgrades just completed. We chose the Predator flash programmer--the specific unit made for this make and model vehicle. Simply plug the hand-held unit in and follow the instructions.With the ignition turned on, the program installs into the truck's computer system and the tuner is installed onto the vehicle Once connected, the flash programmer recognizes this vehicle's PCM and automatically picks the proper tuning files designed specifically for that PCM. The programmer's memory retains predetermined tuning files that optimize spark timing and air/fuel ratio curves.
With this particular unit, programming is performed in small increments throughout the entire RPM range for a smoother, wider and a more predictable power delivery. The additional power provided by the predator results in noticeable power increase in the lower RPMs that gradually increases in the higher RPM range. Programmed vehicles benefit from improved shift patterns, quicker acceleration and better mileage for both city and highway driving. Average gains from programmed tuning are in the 15-20 rwhp (rear wheel horsepower) range. Important: Included in this summary are the steps in these automotive procedures as shown in the episode of Weekend Mechanic. These steps are general guidelines that are applicable to most vehicles. With any particular car or truck, there may be procedures, specifications, settings, tolerances, components, etc. that are specific to that vehicle. There are also variations according to the type and brand of upgrade-kit or replacement part that you select. Always consult your vehicle's service manual when undertaking significant automotive repairs, and read and follow the manufacturer's directions and precautions that come with your kit or replacement parts.
