Will the vehicle still be affected after unplugging this product from it?
Ropode AFM/DFM keeps the factory ECU and will not reprogram the vehicle's ECU. Therefore, after unplugging it from the vehicle, it will not have any impact on the car, nor will it leave any records on the vehicle.
Will this product drain the battery after the vehicle engine is turned off?
Will this product drain the battery after the vehicle engine is turned off?
After technical upgrades, the standby power consumption of the Ropode AFM/DFM disabler has been significantly reduced. However, if the vehicle is not used for a very long time, we suggest unplugging it.
Will my fuel economy get worse?

AFM/DFM was designed to save fuel by deactivating cylinders at highway speeds. Disabling it may result in a slight decrease in MPG — typically 1-2 MPG depending on driving habits. Most owners consider this a fair trade for engine protection and smoother driving experience it provides.
