■ Description
･Mapping
There are three setting types:
(1) Fuel Injection (FI) and Ignition (IG)
Intuitive and easy adjustment by selecting "Smooth ⇔ Aggressive". If you want more detailed settings, you can adjust each with 16 points (4 x 4) according to the engine speed / throttle opening.
(2) Traction Control
Adjust the level of intervention within 3-4 levels.
(3) Launch Control
Set the "Rev limit" for launches.

･Monitor
The race log, failure diagnostics, machine status, vehicle speed, throttle opening, engine speed, fuel consumption, water temperature, intake air temperature, and battery voltage are displayed on the smartphone.

･Lap timer (Time)
Measure lap times with “Multi-function Button” on the left handlebar. After, check the data recorded by the machine's CCU on your smartphone. Since lap-by-lap measurement is available, you can numerically check the settings effect and lap time discrepancies in actual races.

･Set Up
A FAQ-style setup guide is available for engine and suspension settings. Since it is easy to check the setting instructions on your smartphone, anyone can easily setup the engine and suspension.

･ECU Lock
ECU Lock is a theft deterrent feature that, when engaged, prevents the engine from being started.
