MULTI GAUGE

DESCRIPTION
Multi-gauge unit is located at the upper portion of audio system and it indicates engine torque, instantaneous fuel consumption, and battery voltage.

1. Engine torque gauge
It indicates the instantaneous torque variation according RPM of the vehicle. Driver can notice the instantaneous torque variation with oscillation and outrunning speed, recently a lot of consumers want their sports car with performance tuning. They can discern the torque level easily. Engine torque gauge indicates the engine torque value by communicating CAN signals from engine ECU.

2. Instantaneous fuel consumption gauge
It indicates instantaneous fuel consumption according the driving condition.
Instantaneous fuel consumption gauge inputs the speed signal and fuel injection signal.
Speed signal comes directly from the speed sensor and fuel injection signal is from the engine ECU.
Multi-gauge reads the two signals for 500 msec. and calculates the instantaneous fuel consumption. If the vehicle speed is increasing by constant fuel quantity per hour, the gauge indicates the value increasingly. It doesn't show the average fuel consumption but only the instantaneous one.

3. Volt gauge
Volt gauge makes a driver properly response during low voltage, informing the vehicle voltage.

Before ignition turned on, when the key is inserted into "ignition switch on" position, it displays the battery voltage, after ignition key turned on, it displays the ignition voltage (battery voltage).

If the voltage is at 8.5 V or below, the pointer of the gauge moves to the lower than 8 V and if it is at 16 V or more, it moves to the lower than 16 V.
If the input value is between 8.5 V and 16 V, the volt gauge points the battery voltage (Ignition voltage is displayed during the ignition key turned on).
