BACK Why do I need a wide band A/F sensor? I can buy a kit that ties into my factory oxygen sensor for a lot less money.

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 Motorcycle 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.

BACK What A/F ratio should I be looking for when I'm tuning?

On a naturally aspirated engine, you'll make best / safe power between 12.8-13.2. Vehicles running "power adders" will need to run a little richer, between 11.5-12.5 for best / safe power.
BACK I have a Motorcycle.  Do I need to install Everything in the Kit.??

Absolutely, Not.  Motorcycle Installs are very easy.  To get the most out of the wideband, All you need is to Tap the Pick-up for the Throttle Position(TPS) and the RPM's and Screw in the Wide Band 02 Sensor.  That's IT.
No need to use the guage, or Other Aux. Outputs if you don't want to.  This makes install about 50% easier and quicker.  (Note, if your bike's exhaust doesn't already have a  Bungle, you will need to get one welded on)
The Great news is.  More and More Stock and Aftermarket Motorcycle 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.
BACK My vehicle utilizes a coil-on-plug ignition system, do I need a tach adapter to allow the WBC to "see" RPM?

The WBC uses the same RPM acquisition technology found on our world class dynamometers. It is NOT necessary to run an aftermarket tach adaptor, the WBC includes the harness (1 wire hook up) to acquire an RPM signal.
BACK What is the "Programmable Relay Output"?

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!

BACK I don't have a laptop computer, can I still use the WBC?

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.

BACK Do I need a laptop to datalog?

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!

BACK Does the WBC system replace my factory oxygen sensors?

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 Great news is.  More and More Stock and Aftermarket Motorcycle 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.

BACK Does the sensor also carry a 12 month warranty like the rest of the kit?

The sensor itself is not covered under this warranty.

BACK The WBC requires a "key on" 12v source, where can I find this on my vehicle?

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!

BACK Is the WBC waterproof?

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.

BACK I have other gauges in my car and I would like to match their look, do you offer other styles of gauges?

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.

BACK I have a stand alone engine management system in my vehicle, does the WBC have an output I can use?

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

BACK Why does my WBC seem to log data quicker when I’m using the internal memory as opposed to logging to my laptop?

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.

BACK How long is the cable from the sensor to the WBC control module?

72”

BACK I have an aftermarket ignition system on my vehicle, will I have a problem getting an RPM signal?

Even though many aftermarket ignition systems / plug wires emit more noise than the OEM system, the WBC won’t have any issues acquiring a signal. There are provisions in the software to configure the sensitivity to meet you needs.
BACK Can I use a USB adapter to attach to the RS232 serial port on my laptop for configuring and downloading in the car?

We have found that this method either does not work at all, or is completely unstable. It is best to use PC / laptop configured with a USB port.
BACK Are software / firmware updates covered with the initial purchase price?

All software updates will be free of charge and can be downloaded here or by visiting our software section.  Firmware updates can be made in the field, there is no need to send the unit back to Dynojet.
BACK I received a 9v power adapter with my WBC kit, what's it for?

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.

BACK Playing back the datalog sessions in the software is a nice feature, but can I export the data to Excel?

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.

BACK I'm interested in the Power Commander and the Wide Band Commander, what's the difference?

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!

BACK I noticed my TPS display in the software is not stable, why is this?

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.

BACK There isn't a gauge pod available for my vehicle, so I'm thinking about mounting the gauge in different location . What are the dimensions of the gauge?

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.

BACK Will the WBC keep my settings in the event I disconnect the battery or lose power?

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.
