- Fine-tuning car engines takes a new twist
-
-
- Hot rodding used to be a pretty straightforward hobby. Once
- you'd mastered manifolds and camshafts, all you had to worry
- about was how to get the money for your engine parts and the
- grease off your hands. Then in 1981, Detroit, pressed to reduce
- emissions and improve fuel efficiency, started putting
- something new in their cars: computers. Suddenly, anyone who
- wanted to fine-tune an engine had to have a degree in data
- processing.
-
- No problem. A lively market has now developed for so-called
- superchips, plug-in brains that replace factory-supplied engine
- chips and offer a variety of improvements, from better gas
- mileage to higher horsepower. Today half a dozen U.S. firms, led
- by Memphis-based Hypertech, sell some 40,000 high-perform ance
- chips a year for GM cars and Fords, as well as for imports made
- by Nissan, BMW and Porsche. Average price: about $130.
-
- The superchips represent the merger of two quintessentially
- American pastimes: car customizing and computer hacking. When
- the first "engine management" chips debuted, some bright young
- computer types broke the coding and discovered that the tuning
- devices supplied by the manufacturers were designed for average
- drivers using low-octane fuel and left considerable room for
- improvement. With some minor adjustments, the processors that
- control engine timing and gear shifting could be reprogrammed
- for speed demons burning high-test to increase horsepower
- anywhere from 10% to 30%.
-
- Of course, when you pop out your stock chip and replace it
- with a superchip, you break your warranty and you may violate
- the Clean Air Act, which was amended last year to require that
- high-performance parts meet the emissions standards of the car
- for which they are built. Today most superchip makers are
- scrambling to bring their products up to that code. Meanwhile,
- a California start-up called Adaptive Technologies has
- introduced a nifty gadget that lets you drive around in your
- superchipped wheels and then, when it's inspection time, switch
- back to the original chip with a twist of the wrist.
