Racepak Air Fuel - Wide Band O2

Racepak has an excellent selection of A/F controllers and sensors created specifically for tuning race engines. Each of these 2 and 4 channel controllers are designed to be connected to the V-Net cable of Racepak V-series recorders. All sensors have a 13” pigtail cable, and the controller has a 37” cable for attachment to the sensor. These lengths cannot be altered. Controllers are ordered by cylinder bank layout.

Racepak A/F sensors are compatible with either gasoline or methanol fueled engines. Gasoline application will display A/F ratios between 9.55:1 and 20:1, while methanol is shown from 4.22:1 to 8.7:1. Please specify the type of fuel you will be using when ordering. Each sensor includes one weldment and plug.

Air/Fuel sensors can be used with all Vnet products and can run on 12-18 volt battery systems.

Additional weld bungs & plugs as well as stainless bungs are available in single packs or any quantities.

220-VM-AF1 O2 Components 1. Sensor - is threaded into the header to get samples of exhaust. 2. Controller - receives the  the samples taken by the sensor converts them to fuel type and formats the info for the recorder. The controller also handles the heater circuit and calibrations. 3. Vnet connector - connects the O2 "system" to the recorder network (just like fuel pressure or boost) Wire lengths: 1. Sensor - 12" 2. Sensor plug to controller - 36" 3. Vnet plug to controller - 16" 4. Power - 46"

 

O2 bungs are to be welded in a primary tube 8-12" forward of the collector. Some racers get away wit using one a collector but usually will experience choppy readings at lower RPM.	Click to expand
