The Latest Great Stuff For Your Driving Life

Sprint Booster
Drive-By-Wire Enhancer N Drive-by-wire technology has enabled car manufacturers to calibrate vehicle throttle response and power delivery based the vehicle's weight, its drivetrain, and its intended use. The Volkswagen/Audi 2.0T FSI engine is used in variety of vehicle types-from a small hatchback to a large four-door sedan with a weight difference of over 500 pounds. Weight is not the only factor, though. If the vehicle is two- or four-wheel drive, the transmission type (i.e., traditional automatic, traditional manual, CVT, or DSG) and even the tires come into play when the manufacturer calibrates how the throttle pedal responds based on driver input. The wide range built into the factory system is what the Sprint Booster module taps into to enhance throttle response and eliminate throttle delays.

If we look at the '07 Volkswagen GTI 2.0T FSI equipped with a DSG transmission, it's obvious that when software engineers calibrated the throttle map they had several things to consider. The GTI is classified as a performance car, with an output of 200 horsepower and 207 lb-ft of torque on 91 octane. It is front-wheel-drive, weighs 3,100 pounds, and can be equipped with all-season tires. Though the GTI is a performance car, VW wants to optimize gas mileage to have better EPA efficiency numbers on the window sticker. So here's how they calibrate the throttle map. Since it's FWD potentially running with all-season tires, engineers program a slight initial delay in throttle response to prevent a loss of traction. The problem is they are unable to program the delay based on the driving situation, so it's always there, whether you need it or not. Because of the vehicle's performance class, they do increase the throttle response after the delay, but because of the vehicle's weight and fear of customer complaints, it's set on the extreme minimal end of the spectrum.

The Sprint Booster module is designed to eliminate the initial throttle delay and increase throttle response. It works by intercepting OEM signals from the fuel pedal and recalibrating them before they reach the engine control unit. We tried it on an otherwise stock '07 GTI with the DSG, and the unit performed as advertised with no adverse effects on how the vehicle shifted. The throttle did not become jerky or erratic, but remained smooth and precise.

The Sprint Booster is 100-percent reversible and can be easily removed in about 10 minutes, leaving zero trace of it ever haven been there. -Anthony Gelinas
