Universal OBDII Oxygen Sensor Simulator

OBDII O2 sensor simulator for off-road applications. This device replicates the signal and heater from a  rear O2 sensor so that the user may run without a rear sensor or catalytic converter. This is advantageous in racing applications involving high flow turbo-back exhaust.

This unit is universal and will replace any 0-0.9V post-catalytic Nernst oxygen sensor found on OBDII production vehicles. Compatible with most domestic and import vehicles.  

The Suprock Technologies O2 Simulator is made exclusively from traceable aerospace grade electronic components. For example, Suprock Tech makes use of the latest surface mount technology including high-value multi layer ceramic capacitors. The quality of the components is critical for longevity and reliability. As a design firm for the aerospace industry, Suprock Tech spares no expense to produce the highest quality product. The quality shows, even in the printed circuit board where the FR4 substrate bears a photo developed gloss black solder mask. The use of screw terminal connectors is another sign of the high quality and attention to detail on this product. An added touch of detail is the white-blue diamond 8200k LED's used on the design. These  LED's are a true reflection on the design detail of the Suprock Tech O2 sensor simulator and show a commitment to implementing cutting edge component technology. This device is for OFF ROAD USE ONLY and bears no DOT approval. It is intended for use during track races, rally racing, drag racing, or other sport racing events to prevent check engine light from illuminating during the off road driving.

Special Compatibility Notes:
The device is compatible with Subaru WRX ECU's and can work in conjunction with Cobb Tuning Accessport system. Using the Accessport, users can turn on the CEL codes related heated catalyst and rear 02 sensor while using the O2 sensor simulator to provide signal to the ECU. This eliminates problems associated with "not ready" status encountered during OBDII emissions diagnostics.
