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. From pro class competitors to weekend warriors, Edelbrock's QwikData data acquisition systems offer all of the benefits of a higher priced unit at a fraction of the cost. All QwikData Systems feature a 32-bit Motorola processor, 1-mb of non-volatile memory, real-time display, rpm and voltage input, fully assembled wiring harness, analysis software, users manual, and internet upgrade download capability.
