Usage Tips:90 ANGLE EMULATOR LAMBDA PROBE WITH CATALYTIC CONVERTER FOR CARS WITH EXHAUST GAS ENGINES: --- EURO3/EURO4/EURO5 ANGLE EMULATOR WITH CATALYST INSIDE!!! If the catalytic converter is removed, damaged or replaced with a jet, the engine often goes into emergency mode, which is characterized by a large power drop, and an error "CHECK ENGINE" is displayed on the board. To compensate for the error, it is necessary to install a lambda sensor emulator. The catalytic converter is able to effectively reduce engine power by 2-3%, and at revolutions for maximum power it can be up to 5%. Its removal and assembly of the emulator is the cheapest way to increase power. The LAMBDA SECOND PROBE ANGLE EMULATOR is also designed for cars with LPG installation. In these cars, as a result of detecting too rich mixture, the “CHECK ENGINE” light comes on. Installation of the emulator is not complicated. After removing the lambda probe, screw the emulator into its place, to which we mount the probe.
