      Speedo Calibrators and Tranny Controllers Let You Re-Engineer Your Ride
      Many auto enthusiasts are driving around with speedometers registering too low a speed because they've mounted bigger tires on their vehicle. This effect occurs because larger tires have a greater overall circumference (distance around the outer edge) than smaller ones do. A tire with a larger circumference will cover more ground per revolution, and it will also make fewer revolutions in a mile than a tire of smaller diameter.

      Data Monitors and Loggers Provide Access to Important Drivetrain Info
      If you're tuning a modern engine, there's a lot of information you'll need to know in order to make educated adjustments and avoid trial-and-error guesses. Keeping track of air/fuel ratios, fuel pressures, boost pressures, and rpms is difficult at speed, and trying to commit them all to memory is almost impossible - assuming you even have readouts for these items. Maybe all you need to do is closely watch how temperatures and other things are affected by stop-and-go traffic. Or maybe you take your vehicle on track runs. If so, you already know splitting your attention between gauges and driving just causes you to lose focus on both. Because you can't take notes while driving, we offer a practical and effective solution for the tracking of engine data - recording it electronically for later playback.

      Why Should I Add a Throttle Controller?
      Modern cars and trucks are constantly evolving, mostly due to advancements in electronics. This allows vehicle systems previously controlled by mechanical hardware to be run by computers that have processing power undreamt of several short decades ago. When applied properly, this processing power can wring out higher levels of a vehicle's built-in power and responsiveness, without physically making any engine upgrades. One such system found on today's fuel-injected vehicles is electronic throttle control, commonly known as drive-by-wire.

      Are Superchips Really Super?
      In today's ultra-competitive automotive world where fuel consumption, horsepower, and emissions are paramount, modern vehicles are controlled by computers in order to meet these opposite and conflicting demands. And presiding over the multitude of separate computers on any vehicle is the ECU (Engine Control Unit) - sometimes called the ECM (Engine Control Module).
