Smart Power Logic: Perfect Compatibility for Old and New Cars

FD EVO features built-in smart power logic that automatically manages power on/off based on the vehicle's actual status. This avoids battery drain caused by long standby times and eliminates the need to modify the original vehicle wiring, lowering modification risks. This design ensures stable use of the digital gauge across different generations of vehicles.

In electronic product development, Shadow always regards "not affecting original vehicle safety" as a fundamental principle. Many owners worry that modifying gauges will cause battery drain or compatibility issues; FD EVO was born to resolve these concerns.

For vehicles equipped with CANBUS (approx. post-2014), FD EVO uses standard OBDII mode, syncing wake-up and sleep with the ECU for true plug-and-play. For classic older cars or special modification needs, the power can be controlled independently via ACC mode.

In an era where vehicle electrical systems evolve rapidly, compatibility is a key factor in modification that cannot be ignored. FD EVO supports 12V gasoline and diesel vehicles and is compatible with 48V mild-hybrid systems (Pure EV and 24V trucks are not supported), ensuring every car can be upgraded with peace of mind.
