*WHY USE A WIDEBAND AIR/FUEL CONTROLLER?*Īccurate AFR data is critical when tuning an engine. An analog output for O2 feedback is provided for users without AEMnet or CAN-equipped devices to hard wire the gauge for O2 feedback or logging in a stand-alone logger. Non AEMnet devices can communicate with the device using the CAN 2.0B spec protocol. Users with an AEMnet-equipped (CAN bus) device can daisy chain the Wideband FAILSAFE gauge using the AEMnet connection (adapter sold separately).

Once installed, users connect to the gauge via a USB port and use the supplied software to log an engine’s safe AFR operating range, set minimum and maximum AFR ranges, alarm mode, time delay strategy, failsafe strategy and gauge display configuration. Available failsafe strategies will ultimately be dependent on the capability of the EMS or piggyback engine controller. The aforementioned strategies are provided as an example. Users with turbos can also trigger the device to cut boost (may require separate solenoid).

NATURALLY ASPIRATED, TURBOCHARGED OR SUPERCHARGED WITH STAND ALONE EMS OR PIGGYBACK CONTROLLER: Can use the low side output to cut revs, retard timing, trigger a separate fuel or ignition map and activate an ancillary warning light.
