The two OEM O2 sensors are located in the downpipe, the sensor for the wideband is in the midpipe (almost directly beneath the passenger seat) So there are three O2 sensors, two being used by the ECU and one being used for the datalogger/wideband
There is no standalone engine management. The factory ECU is used and has been reflashed by Turbonetics. For any additional corrections the APEX'i AFC Neo can be used to add/remove fuel at specific loads / RPM.
