It's no secret that successful racers rely on data acquisition systems to give them the winning edge, but until now they have been too expensive for the average racer. Edelbrock's QwikData data acquisition systems offer all of the benefits of a higher priced unit at a fraction of the cost for pro class competitors to weekend warriors. Includes one built-in accelerometer, four EGT thermocouples, fuel and oil pressure sensors, rpm input, battery voltage input, one wheel/shaft speed sensor, wiring harness, Windows 3.1/95/98/NT analysis software and owners manual.
