Ⅱ. About the product

(1)

This product is a fuel controller that enables a ±50% of fuel adjustment and a function that can optically

communicate with the R-VIT. The user can logically compensate the fuel at a rate of 0.1% within the set

parameter of 16 points. The 16 points parameter can be set by every 100RPM. Furthermore, together with the

sister product R-VIT, an easy fuel adjustment that was not possible until now will be available by

communicating the engine RPM and the throttle signal optically through the R-VIT. As a result, the time and

effort of a confusing wiring work could be saved. Moreover, with turbo charged vehicles equipped with Hot Wire

type airflow sensors, it has a function to prevent engine stall caused by air blow back at the time of throttle

OFF.

① Easy set up function

This product can be used immediately and the troublesome initial setting is unnecessary at all by selecting the
pre- loaded set up data classified by vehicle (maximum of 64).

R-VIT, which it leads to an easy and minimum wiring work.

④ Engine stall prevention function

ellipse meter, the digital bar graph, and the 2D/3D trace screen.
