Top Speed - Hypertech 2000 Reference Manual And Step By Step Installation Manual

your engine's rpm limiter to improve performance and driving fun. The stock computer is programmed
to shut down the engine when it reaches the redline. But if you have modified your vehicle to increase
its high-speed performance, more rpm means more power. When you shift gears at 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 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.
Use the buttons to the right of the screen to scroll up or down, and highlight the value to increase or
decrease the engine rev limiter. Press 'Select' to save the chosen value.

TOP SPEED

Use the buttons to the right of the screen to highlight Top Speed. Press the 'Select' button to adjust the
top speed limiter. 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 OEM 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, 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.
