Hypertech is a technology leader in high-performance engine tuning of computer-controlled vehicles. Electronic engine controls have evolved rapidly since their introduction in the early 80s. Hypertech has kept pace with these rapid advances in technology by developing power tuning products that take advantage of the capabilities of these electronic controls. Early automotive computers used replaceable PROMs or chips to calibrate the Electronic Control Module (ECM) for a specific engine, powertrain, and vehicle combination. Hypertech created the original Power Chips to recalibrate these electronic brains for improved performance.
Later generations of Electronic Control Units (ECU) eliminated calibration chips. Instead, engine tuning information is stored in the units programmable memory. In addition to controlling basic engine functions, microprocessors now monitor and govern a wide range of systems, including the transmission, brakes, instrument panel, emission controls, and heating/air conditioning. For comparison, the code stored in an early chip would fill one page; now a typical ECU contains more than 1,600 pages of code!
Hypertech created the Power Programmer to access this flash memory and download the Hypertech Power Tuning program directly into the ECUs programmable memory. In addition to controlling engine functions such as air/fuel mixture, spark timing, and maximum rpm, these highly evolved ECUs also regulate transmission shift points and firmness, limit top speed, and display speedometer and odometer readings. Hypertechs engineers were able to use these capabilities to provide additional features for diesel enthusiasts.
The Power Programmer is much more than a tuning chip it is a self-contained automotive tuning computer. The Power Programmer automatically installs the powerful Hypertech tuning program. It also allows enthusiasts to access and reprogram the vehicles computer to function properly with aftermarket components such as non-stock wheels, tires, and rearend ratios. A Hypertech Power Programmer is one of the most powerful and versatile tools a performance enthusiast can own!
