curve. When you extend the engine’s rpm range with the Max Energy 2.0, your engine has more power
available after gear changes. And by keeping the engine in the “sweet spot” of its power curve, you can increase
the average horsepower that accelerates the vehicle.
TOP SPEED
This feature lets you electronically raise your vehicle’s top speed limiter to match the speed rating of factory-
approved high-performance tires, or lower the top-speed limiter from 25 to 75 MPH.
The maximum speed of many modern vehicles is governed by the onboard computer. The stock computer is
programmed to shut down the engine when the vehicle exceeds the speed rating of the original equipment tires.
But if you have installed tires with a higher speed rating for off-highway competition in sanctioned events, your
vehicle may be able to achieve a higher top-speed. A tire’s maximum safe speed under perfect conditions is
marked on its sidewall. Codes for popular high-performance tires are: T=118 mph, U=124 mph, H=130 mph,
V=149 mph, Z=149+ mph. This feature may only be used with Factory approved speed rated tires.
The option to lower the top speed limiter is available to restrict the driver to a maximum speed limit. Some
examples of the use of this feature are to limit the speed of inexperienced drivers, valet parking, or fleet vehicle
management. The top speed can be limited from 25 MPH to 75 in 5 MPH increments.
NOTE: Always obey Federal Traffic Laws. Do not raise the vehicle top speed limiter above the speed rating of
the tires installed on the vehicle. Raising the vehicle top speed limiter above the speed rating of the tires
installed on the vehicle may lead to a serious or fatal accident.
TIRE SIZE
This feature recalibrates the speedometer and odometer, and the part throttle shifting for auto transmissions
(some vehicles), if non-stock tires have been installed on the vehicle. This option is adjustable in ¼ inch
increments. It is critical to measure the actual tire height. This is the total diameter of the wheel and tire
together, as measured distance from the ground to the top of the tire, at the centerline of the wheel. Make sure
the tires have proper air pressure. Compare your settings to a GPS, and adjust the height up or down as needed
to dial in the exact calibration.
Another method of measuring the tire diameter:
1. Place a chalk mark on the tire where it contacts the pavement and also mark the pavement. These marks
should be at the center of the tire footprint pointing straight down to the pavement.
2. Roll the vehicle in a straight line until the chalk mark makes one revolution and is pointing straight down at
the pavement again. Mark the pavement again at this new spot.
3. Measure (in inches) the distance between the two (2) marks on the pavement. Divide the measurement by
3.1416. This will give you the tire height in inches.
GEAR RATIO
This feature will recalibrate the speedometer and odometer readings, and part-throttle shifting for automatic
transmissions (some vehicles), if an aftermarket gear is installed. Go to www.Hypertech.com, and look up your
vehicle information to determine the list of gear ratios supported for your vehicle.
SHIFT POINTS (Auto Transmission Only)
This feature allows adjustment of the wide open throttle shift RPM for each gear. This adjustment is typically in
100 RPM increments. This setting does not affect part throttle shifting. To determine the factory shift point in
each gear, accelerate the throttle wide open while in Drive, and hold it until the transmission shifts. Note the
RPM when the gear change occurs.
