Hypertech is the technology leader in high-performance engine
tuning computer-controlled vehicles. Electronic engine controls
have evolved rapidly since their introduction in the early '80s.
Hypertech has kept pace with these rapid advances in technology by
developing power tuning products that take advantage of the
capabilities of these electronic controls. Early automotive
computers used replaceable PROMs or "chips" to calibrate the
Electronic Control Module (ECM) for a specific engine, powertrain,
and vehicle combination. Hypertech created the original Power Chips
to recalibrate these electronic "brains" for improved performance.
