The Haltech Wideband Controller is a stand alone unit used to measure the Air/Fuel ratio or Lambda for an engine which uses a Bosch sensor. This system can be calibrated for Gasoline, LPG, Methanol, Ethanol, CNG and diesel.
The Haltech Wideband Controller can be displayed as an AFR on a display screen, which is sold separately, otherwise can be displayed on your laptop through your Haltech Engine Management System. This Air/Fuel ratio (AFR) can then be logged as a true AFR for later analysis. The Wideband Controller has two programmable outputs, making the unit a perfect addition to your engine management system, with the second output used for closed loop O2 correction. It can also be used in conjunction with the display as a workshop tool, or to move from car to car when tuning.
