A typical production vehicle uses oxygen sensors that have a very narrow resolution. When you are cruising / idling (closed loop), the vehicle is concerned with maintaining an A/F ratio of 14.7 (stoich). When you put your foot on the floor and go into power enrichment (open loop), the factory sensors do not have enough resolution to tell you an exact A/F ratio. Any system that ties in to the factory oxygen sensors can only tell you if you are richer or leaner than 14.7. The Wide Band Commander, utilizing the Bosch LSU4 wideband sensor, will tell you exactly what A/F ratio you are running.
The Great news is.  More and More Stock and Aftermarket   Systems are coming with O2 Sensor Bungle already welded  on the Exhausts Systems from the Factory.  Namely,  80% of Akrapovic Evo & Race Systems, The Micron Serpents CBR1000RR...etc..etc
What this means, is install is a snap.  Simply Scew in the Wide Band O2 Sensor, and your good to go. No Welding required. Simple Wiring, required to finish the install and your are on your way.

This output is designed to control the ground circuit on a relay system. The software is configurable to control the circuit based on 1, 2, or all 3 of the WBC inputs. Here's an example, lets say you have a nitrous oxide system on your vehicle. You would tie the "Programmable Relay Output" wire into the wire that provides the ground for the relay on the nitrous system. The WBC software allows you to define the logic as follows - "if TP is greater than 3v, and if RPM is greater than 3k, and A/F is less than 13.2:1" - then go ahead and provide a ground path for the circuit. If you would like to simplify this logic, you could just say - "if RPM is greater than 3k" - then go ahead and provide a ground path. There are many different strategies and logic available with this provision!

You can certainly still use the WBC effectively without a laptop computer. If you choose to only wire in the WBC module, the sensor, and the gauge, you won't have to configure the TP and RPM channels in the software. When you do choose to install the TP and RPM channels, they do require a configuration routine available through the WBC software.

NO! You can datalog 1 of 2 ways, either to the laptop using the WBC software, or directly to the WBC module using its internal memory. If you want to log without a laptop, simply install a switch on the appropriate wire on the WBC module (refer to the installation guide). You can download the log session at a later time when it's convenient to you!

Absolutely not! The WBC kit includes the appropriate weld boss that needs to be welded in a location that is defined in the installation guide.

The sensor itself is not covered under this warranty.

The best place to find a "key on" 12v source is at, or near the fuse block. Be sure to make sure that the source is "key on", otherwise you'll drain the battery. The WBC sensor REQUIRES power any time the vehicle is running!

Even though the WBC is housed in an enclosure, and the circuit board is potted, the unit is considered water resistant. We highly recommend installing the WBC in an area that is free from moisture, heat, and dirt.

Our initial release is only available with black bezel / white face, or silver bezel / black face gauges. In the future we will be releasing other gauges, both digital and analog, to meet the demands of our customers.

Yes, the WBC does have a 0-5v or 0-5 mA linear output.

Due to system resources on your laptop, the log sample may not be as quick as the internal logging feature. To optimize the sample rate (up to 10 / sec), we advise that you use the internal logging feature.

The 9v power adapter plugs into the white connector (10 pin) on the side of the WBC. It is used to power up the WBC in the event that you didn't have it wired to a 12v source. We envision most people will leave the WBC hard wired to their vehicle, but a few people may do a "temporary / mobile install". This will allow you to power up the WBC in a remote location to download any log sessions or even configure the light / relay with their PC.

Yes, when you have a datalog session open, you can go to the “File” menu and select “Export Data”. This will allow you to export the data as a text file, and from there you can save it in a format that can be imported easily into Excel.

The Power Commander is a device that allows you to make changes to the fueling characteristics of your vehicle. The Wide Band Commander is a device that allows you to monitor / review how rich or lean your vehicle is running. Currently we only have Power Commander applications for motorcycles (www.powercommander.com), but the Wide Band Commander can be used on most anything with a 12v source and burns petrol fuel!

This can be caused by a poor ground. If both ground wires are grounded to a very good ground, then the digital ground wire (black/wht) should not be affected by the heater ground (black). To get the best possible TPS reading on the Wide Band Commander, connect the blk/wht ground to the TPS ground and the heater ground (blk) to the engine or battery cable.

The gauge is a standard 2 1/16" like most of the other performance gauges in the market.  If the depth becomes an issue because of the threaded mounting studs, you can certainly trim them to fit your application.

The settings you define in the "Device Settings" will be saved in the event that the WBC loses power. The WBC stores these settings in a non-volatile EEPROM environment.
