About Defi
Defi is the aftermarket brand of Nippon Seiki Co., Ltd., which was founded in December 1946 in Nagaoka, Niigata Prefecture, to make clocks and instrument gauges. A project team formed in 1995 to bring its gauge technology to tuners, and the Defi brand launched in 1996 with a retrofit head-up display.
In 1998 it introduced the Defi-Link Meter, and in 2018 the DSDF data logger added a GNSS lap timer. Defi makes gauges, displays and sensors for Japanese cars, and tests them at circuit events.
