Description
More Power. Unlock the hidden power potential that your vehicle has to offer, with a Hypertech Max Energy Power Programmer. The Max Energy Power Programmer comes preloaded with Hypertech's very own pre-configured tune files. In order to increase engine efficiency, horsepower and torque, Hypertech engineers first optimize the spark and fuel curves point by point over the entire rpm band. With the additional power and optimized transmission functions, drivers use less fuel to accelerate and maintain cruising speeds without the torque converter un-locking and transmission down-shifting to a lower gear. The results are maximum power and fuel mileage.
Speedometer Calibrator. If you have installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Max Energy Power Programmer allows you to re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. The vehicle’s computer calculates your speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is actually going. As a result, the automatic transmission may not shift correctly and the speedometer/odometer readings will not be accurate.
Top-Speed Limiter. Automobile manufacturers limit a vehicle’s top-speed to match the speed rating of the factory-installed tires. If you have installed tires that have a different speed rating, the Max Energy Power Programmer allows you to raise or lower the vehicle’s top-speed limiter to match the speed rating of the newly installed tires. A tire’s speed rating for maximum safe speed under perfect conditions is marked on its sidewall. Always obey all traffic laws when driving and only use this feature for off-highway competition in sanctioned events.
Automatic Transmission Adjustments. Shift Point - The Max Energy Power Programmer allows you to raise or lower the shift points in 100 RPM increments for maximum performance, quicker acceleration, and better 1/4-mile times. With the Max Energy Power Programmer, you have the ability to customize the shift points for every gear. Optimizing each shift point can definitely improve performance. Shift Firmness - Increase shift firmness to maximize performance or when towing, to reduce clutch slippage and transmission oil temperatures. That means longer transmission life. However, this feature must not be used If you have installed an aftermarket shift kit.
RPM “Rev” Limiter. In today’s vehicles, the onboard computer controls maximum engine rpm. The stock computer is programmed to shut down the engine when it reaches its redline. But if you have modified your vehicle to increase its high-speed performance, more rpm means more power. When you shift gears with the stock rpm limit, the engine falls back to below the peak of its horsepower curve. When you extend the engine’s rpm range with the Max Energy Power Programmer, your engine has more power available after gear changes. By adjusting the maximum rpm to keep the engine in the “sweet spot” of its power curve, you can increase the average horsepower that accelerates the vehicle.
Cooling Fan “On/Off” Temperatures. The Max Energy Power Programmer allows you to adjust the “on/off” temperatures of your vehicle’s electric cooling fans to match a lower temperature thermostat, such as a Hypertech PowerStat. A low-temperature thermostat produces a cooler, denser intake charge, and is less likely to detonate under heavy loads and allows the engine to make more power.
Diagnostics Tool. The Max Energy Power Programmer can also be used as a diagnostic code reader. Save yourself time and money by reading and clearing your own Diagnostic Trouble Codes (DTCs)
