## VVT duty cycle

The VVT control table function varies depending on whether on/off, open or closed loop VVT mode has been selected.
- In On/Off mode, 100 is taken as "output on" and any other values represents "output off". Values 0 and 100 are recommended to use in this mode.

- In open loop mode, the map values are the duty cycle percents that will be used
