The efie has also another knob for the second narowband sensor .i can mesure there with my multimeter the milivolts that im giving to the sensor ...also i can see the sensor voltag in my diagnostik tool to ghange as i add voltage.I cant feel the car loosing performanse when i tune the back sensor ,,is this normal ??
I can almost get the sensor to 0.9 volts and nothing hapents to the idle ..is it ok ??
