Exhaust Gas Oxygen Sensors (Optional)
The optional exhaust gas oxygen sensor must be mounted in the exhaust pipe near the exhaust header or extractors, usually after the collector. The sensor uses the exhaust gas to detect if the engine is running lean or rich. Many late model engines already have provision for an exhaust gas oxygen sensor and the sensor provided should fit any standard exhaust mount. Some exhaust systems have the sensor mount up to around half a meter (2 feet) down stream from the exhaust headers. If the exhaust system does not have an existing sensor mount then a new mount will have to be welded to the exhaust system. When routing the electrical connections to the exhaust gas oxygen sensor, do not allow the harness to touch the exhaust pipe, as the heat will damage them.
Narrowband O2 sensors can be wired directly to AVI inputs 1 and 6 which have been optimally designed to minimise the load on the 0V to 1 V signal produced by this type of sensor.
Exhaust Gas Temperature Sensors
Up to 12 Exhaust Gas Temperature (EGT) Sensors may be used with various Elite series ECUs. These can be used for datalogging, engine protection, or engine tuning purposes. A common use for EGT input is to allow individual cylinder monitoring and ...
Exhaust Manifold Pressure Sensor
An Exhaust Manifold Pressure Sensor, commonly referred to as a EMAP Sensor, is used to measure pressure in the exhaust manifold. An EMAP Sensor is a powered sensor that typically has three wires; a 5V+ power wire, a signal wire to the ECU, and a ...
Exhaust Gas Temperature Sensor
Sensor Configuration This node allows you to enter a voltage vs temperature calibration when using an external EGT controller that is wired to the ECU via an Analog Input. When the sensor wiring Input Type is set to Thermocouple - Type K, there is no ...
Narrowband vs Wideband: Oxygen Sensors Explained
Today we’re talking Oxygen Sensors: what they are, how they work and why you need them. The Oxygen sensors can usually be found screwed into the exhaust system. They are located closer to the engine than to the tailpipe. Their job is to measure the ...
Knock Sensor (Optional)
Knock sensors detect engine knock and sends a voltage signal to the ECU. The Elite Series ECU uses the knock sensor signal to modify ignition timing if knocking occurs. Knock Sensors can be connected to the knock input connections on the ECU.
