After 2 years of research and development, we came up with this nice RPM gauge with 2 temperatures output. The RPM large digits and the REV indicator bar make it easy to read at high speed. The REV indicator bars can be program for 10 000, 15 000 or 20 000 RPM to make it fit on all type of engines. Other than its RPM and temperature function, this gauge also features the voltage, time and an optional air/fuel ratio output. The programmable shift light and 2 temperature warning light will help you to easily monitor your engine. Its shape and functions make it the perfect race tool!
