Finally, Hypertech has released a Power Programmer III for Dodge truck applications. It's
When we first heard of Hypertech's Power Programmer III (PPIII) a few years ago, we thought, "cool idea!" The ability to customize the programming of a vehicle's stock computer without having to change the ECU or use multiple aftermarket chips to meet varying performance requirements held great appeal. Unfortunately, the PPIII was only available for GM applications at that time. When Hypertech released a version for Ford applications, we started to feel a bit . . . well . . . put out. On the plus side, Hypertech heard our groanings, and just last year the company finally created a PPIII designed for Dodge vehicles.
As most of you are probably aware (and as we discussed in our February issue), there are a host of aftermarket performance chips available for Dodge trucks. The idea behind these chips is to remap engine timing events and fuel ratios based on various conditions, such as load, fuel octane, operating temperatures, emissions, and so on, in order to negate the stock computer's built-in performance limitations. ECU programming via replacement or "piggy-back" chips can boost horsepower and torque in a stock vehicle, and is highly recommended for modified engines in order to take full advantage of upgrades made to the cooling, intake, and exhaust systems.
One disadvantage of the "replacement chip" is that most have only one program. You purchase the chip for your specific application, and there are no additional adjustments available. If you want to change your octane rating or rev limiter, you must buy another chip. The Hypertech PPIII, on the other hand, allows the user to adjust a handful of operating parameters on an as-needed basis (87 or 93 octane, rev limiter, top speed) and revert back to the stock programming in case he or she needs to take the vehicle to the dealer for diagnostic work.
Another benefit of the PPIII is that it's simple to operate. Installation is no more challenging than plugging the unit into the diagnostic port located at the bottom of the dashpanel. Programming your truck's computer involves answering a series of "yes" or "no" questions that you input via the PPIII's control box. That's all there is to it.
You order a PPIII based on your truck's model, year, engine, and transmission, as well as the number on your ECU (a label found on the module). Programming begins with the PPIII recognizing and downloading your stock computer programming into the control box. Once done, the PPIII will take you through a series of questions regarding your preferred octane level, top rpm limit, and top speed (tire rating). You can leave some stock settings and change others depending on the performance you want to achieve. Once you've made your selections, the PPIII will overwrite the stock computer with the new programming parameters you've chosen. Now your truck has optimal ignition timing and air:fuel ratio to squeeze out that extra horsepower and torque. When you wish to change the programming or revert back to the stock settings, it's a simple matter of plugging in the PPIII and going through the process again.
The PPIII is available for '97-'01 Dodge trucks (Ram, Dakota, Durango) with 5.2- or 5.9-liter engines.
