Computer Chip Upgrade

Those parameters include elements of performance, or vehicular behavior, that most non-car buffs aren't even aware of but, nevertheless, deal with every time they put the key in the ignition. Here's a near-layman's version of just a few of those parameters and the changes an aftermarket computer module can make:

Computer Parameters
EXTENDED REV LIMITER provides an extended rpm range, or wider powerband, which comes in handy when you need a quick burst of speed to avoid an accident or enter a fast-moving, crowded freeway. Most drivers understand what the "red line" is—the maximum rpm (revolutions per minute) your engine can handle. The module moves that limit up for more emergency power, but not so much as to put your engine at risk.


COOLER FAN ON/OFF temperatures create a lower, cooler, engine operating condition. This isn't rocket science. The cooler your engine runs, the longer it lasts and the more efficiently it operates. All good things.


FIRMER SHIFT POINTS for automatic transmissions. When those shift points are optimized by speed and rpm, the end result is improved acceleration. Example: You're cruising the freeway in top gear and need immediate acceleration to pass or avoid a high-speed mishap—you need a firm, decisive shift to access your engine's power.


INCREASES TOP SPEED LIMITER to match the top speed to the speed rating of high-performance tires.
