Let's ride the circuit together! Improve your time by carefully analyzing ride characteristics and vehicle condition!
Y-TRAC is a log viewer application for viewing vehicle information collected in the CCU (* 1). Many kinds of vehicle information are displayed visually in an easy-to-understand graph, such as vehicle speed and engine speed, accelerator opening, banking angle and brake pressure, as well as various types of control effects. In addition to vehicle information, position information is recorded simultaneously in the log data stored in the CCU. Due to this synchronization of position information and vehicle condition, you can quickly pick up information such as braking point at corner entry, brake pressure, vehicle speed, line, banking angle at turn, and throttle condition at exit. Since the graph displays each lap, you can easily understand the characteristics of a good line. Find a way to improve your lap time through careful study of the app's features. Circuit racing becomes more and more fun because now you can compare bookmarked data with your competitors.
* To record logs of laps to the CCU, it is necessary to dictate the record line to the CCU in advance.
