Wideband Air-Fuel Ratio Analysis System

FJO Racing Products is very pleased to announce the design and release of its new Wideband AFR controller for the automotive enthusiast. This product is styled after the very popular original FJO Wideband O2 System and is available in single or dual AFR channel models . The wideband controllers are engineered to work with or independently of other FJO products.

These new, exciting controllers offer features like dual AFR channels, dual 5-volt inputs, dual digital outputs and dual user-programmable AFR voltage outputs. Using the FJO WBAFR software, tuners can now datalog RPM, two AFR channels, two 5-volt sensors (such as TPS or MAP) or two EGT channels. Using Leanest Channel Mode it is possible to monitor two AFR channels with only one display. This system also supports interconnecting two dual channel controllers allowing up to four AFR channels to be logged at the same time. With the user-programmable AFR output curve it is now possible to connect this product to almost any device. These features, combined with a user-replaceable sensor harness available in various lengths, provide DYNO owners with a reliable and accurate dual channel plug-and-go solution. Built to the same rugged specifications as FJO's first wideband product, this product now sets a new standard in tuning tools. A mild-steel weld-in bung is included but a stainless version is available--inquire.

• Rugged and Dependable - FJO initially designed and manufactured electronics for military and aerospace applications. They design and build all of their automotive electronics to withstand the same type of harsh conditions. To ensure rugged dependability they use aluminum housings and protect the electronics from moisture and vibration by filling the case with a special epoxy compound.
• Expandability - with their software up to 8 channels can be datalogged or displayed simultaneously.
• Versatility - many OEM or aftermarket ECUs and data recorders lack the ability to enter a custom AFR calibration curve. To eliminate this problem, the FJO Wideband AFR Analysis System has the capability to enter a custom AFR voltage output curve easily and quickly by the end user.
• Leanest Channel Mode - many OEM or aftermarket ECUs lack the ability to monitor more than 1 AFR channel and for dual exhaust applications, this means one side goes un-monitored. The FJO Wideband AFR Analysis System has a unique feature that monitors up to 8 AFR channels (1 per cylinder on a V8 engine for example) and sends the output from the leanest channel to the ECU or Gauge.
• Wide Range - Sensing range from 10:1 to 20:1 AFR for gasoline
• Accuracy - better than 0.1 AFR over the range 10.5:1 to 15.5:1
• Sampling Rate - greater than 200 per second
• Also - RPM Input and comprehensive analysis software (KWB4001), Replaceable Harness, Multi- sensor Support (NTK and Bosch

• Seamless integration with other FJO products
• Free updates/upgrades to software and controller firmware for the life of the product
• Built for the racing environment to withstand heat, vibration, dirt and water
• Free direct technical support from FJO Racing Products (204-254-5623)

Sensors

SO20003 - Wideband AFR Sensor (NTK)

Use this one if you're going to run any racing gas. Requires a CWC0003/CWC0004 controller for operation. (The KWB4000 and KWB4001 include a CWC0004 controller.) Has only about 6" of pigtail. An extension cable (available in accessories) is usually required.

SO20004 - Wideband AFR Sensor (Bosch)

Use this one if you're not ever going to run racing gas. This sensor will quickly fail in the presense of typical racing gas additives (such as lead.) Requires a CWC0003/CWC0004 controller for operation. (The KWB4000 and KWB4001 include a CWC0004 controller.) Has about 18" of pigtail. An extension cable (available in accessories) is sometimes required.

Legacy Sensors

Required for CWC0001 and CWC0002 controllers. Also required for CWC0003 controllers without a brown Sensor Select loop wire and gray O2 connector. Will not work with CWC0003 and CWC0004 with brown Sensor Select loop wire and black O2 connector.

SO20001 - Wideband AFR Sensor (NTK)

For First-, Second-, and early Third-Generation Contollers

Accessories

Wideband Multi-channel Expansion Cables - 1.5- or 4-foot

How many widebands do you want to simultaneously monitor? Add these cables and you can monitor up to eight! You need one less cable than controller, and then two of the terminators, below.

IBT0001 - Wideband AFR Multi-channel Terminator

You'll need two of these (sold individually) and one or more of the expansion cables, above.

IWC0004 - Wideband AFR Sensor Controller Installation Kit

HWB3003 - Clamp-on Inductive RPM Pickup

A handy accessory to have on-hand if you plan on moving your wideband from vehicle to vehicle. Two versions of this have been available. The one shown in the image includes a BNC (COAX) connector but that will not be shipped unless you specifically require it. All of the newer controllers use a weather-pak connector, so that is what will be sent if you do not specify otherwise.

Q: Which sensor should I buy, the SO20003 (NTK) or the SO20004 (Bosch)?

A: There is no simple answer. Although both sensors work very well, there is a difference in their performance. One major difference is that the SO20003 will last longer if used with leaded fuels or in demanding applications. For applications slightly less demanding, the SO20004 would be a suitable option. Because FJO custom calibrates both these sensors in-house, switching between sensor types is a simple controller config change (using the datalogging software included with the controller)

Q: I purchased the SO20004 (Bosch) sensor but I'd like to switch to the SO20003 (NTK) sensor - what do I need to do?

A: Because FJO custom calibrates both these sensors in-house, switching between sensor types is a simple controller config change (using the datalogging software included with the controller). Just buy the sensor you want to use, make the config change and plug it in. That's it!

Q: I bought the FJO controller that was designed to use the SO20001 (NTK-L1H1) sensor. Can I switch my controller to the new SO20003/SO20004 sensors?

A: The sensors are not interchangeable.

Q: I have dual exhaust but my ECU only has one input. How can I be sure that the unmonitored side doesn't go lean ?

A: Use the FJO dual channel controller and a proprietary configuration mode we call “Leanest channel out”. In this mode the WBAFR controller compares the 2 AFR channels and uses the leaner channel to generate the output. It does this continuously so the output to your ECU or data-logging device will always be the leaner side. If one side goes lean … your ECU will know it!

Q: I only have room for one gauge but I have dual exhaust. What can I do ?

A: Use the FJO dual channel controller and a proprietary configuration mode we call “Leanest channel out”.How the digital ports work is a user configurable parameter. The ” Jumper Detect” setting configures the controller to test for the display-jumper on an unused port every time it is powered on. If the jumper is present, the controller will continuously compare the 2 AFR channels and output the leaner AFR reading on port connected to the display. This is the factory default mode for the dual channel controller.

A: The controller can be installed almost anywhere in, on, or under the vehicle. Obviously attaching it to the exhaust manifold is NOT one of those places. to check out a video and see what happens when our Q/A people have too much time on their hands. (we do not recommend trying this but we do come from a MILITARY electronics background...)

A: It would appear that your ECU or datalogger does not have high impedance inputs so it is loading down the analog output from the controller. You will need to calculate a "correction factor" to apply to our published calibration data. A document describing the procedure to do this, along with a spreadsheet is available under our "downloads" section .

A: The controller comes configured with an analog 0-5 volt non-linear output, and a linear 1-0 volt linear output. The calibration data is listed in our installation manual. Check your ECU manual to determine if it is capable of handling this type of input. Optionally, the configuration software can be used to program virtually ANY output curve between 0 and 5 volts.
