O2 Simulator

The AREA74 catsim was developed over two years of research. The catsim is a diagnostic tool developed to eliminate catalyst efficiency fault codes to assist in diagnostics.Essentially a electronic catalytic converter to remove the P0420/P0430 in the most natural way possible to assist in diagnostics The catsim's software uses the natural exhaust levels by using the existing O2 sensor to calculate an output voltage to replicate a catalytic converter. AREA74 was the first and original to assist with the BMW N55. Our technical support also provides assistance for installation and troubleshooting fault codes related to catalyst fault codes.
