The EFIE is not intended to be a fuel saver by itself. The EFIE is designed to be used in conjunction with fuel saver devices, such as a hydrogen gas electrolyzer, a fuel vapor production unit, or other devices that increase the efficiency of the burn.
EFIE Wideband O2: This EFIE will work with all wideband zirconia type of oxygen sensors (Not AFR). All oxygen sensors that were developed before catalytic converter need to own dedicated EFIE device. Oxygen sensors that were developed after catalytic converter do not need EFIE devices, because they are only used by ECU to monitor converter fuel efficiency.

MAIN PANEL MOUNTING
Remove the OEM bezel and gauge cluster from the dash. Remove the entire factory gauge cluster from the bezel. From the back of the bezel, first insert the 5” round spacer so it sits flush against the inside of the bezel. Next, insert the smoked acrylic lens and secure with a small amount of glue, RTV or similar. Insert the speedometer pushbutton into the lens from the rear (the kit includes 2 different size buttons, select the one that fits such that the panel lays flat and the pushbutton has room to move), then install the panel so its sits against the four original retaining screw locations (at the 3, 6, 9 and 12 o’clock positions). The pushbutton will rest against a switch on the panel when properly installed and the LEDs will rest against the lens. Insert the 3 6/32 x ˝” screws through the panel and into the bezel at the original locations (using the approx. 3, 9 and 12 o’clock locations).
