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 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.

Warning
If using “Intelligent” ignitors such as the old Bosch 008 ignition module
(rare), Constant Duty Cycle Mode should be selected in the Ignition Setup
Page. If using a “Dumb” ignitor (Most standard ignitors are dumb, as are
modern Haltech ignitors), the Constant Charge Mode should be selected in
the ignition setup page.
Do not connect the ignition sub-loom to the main wiring loom until after
you have configured the ECU by connecting it to a computer with Halwin
programming software.
