Emulators are a crucial component of automotive gas systems, facilitating seamless interaction between signals read by the control unit when running on gas and the fuel supply. These essential devices effectively eliminate error messages related to injectors, ensuring smooth operation of the car's computer. When installing emulators, it's essential to follow a specialized electrical diagram. The standard kit typically includes the emulator, wiring harness, and necessary mounting elements. Choosing and installing emulators provides confidence and stability for the operation of the automotive gas system.
