WBAFR

FJO Racing Products has released its new Wideband Air/Fuel Ratio Analysis System. This product is similar to the 2nd generation FJO Wideband and supports the same sensors, however the unit is 60% smaller. The wideband controllers are designed to be integrated with all current products that support our wideband, as well as being backwards compatible with most older systems and products.


Questions

  1. Which sensor should I buy, the SO20003 (NTK) or the SO20004 (Bosch)?
  2. I purchased the SO20004 (Bosch) sensor but I'd like to switch to the SO20003 (NTK) sensor - what do I need to do?
  3. 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?
  4. How do I order an FJO product?
  5. What is a NEW PRODUCT TESTER and how do I become one?
  6. I have dual exhaust but my ECU only has one input. How can I be sure that the unmonitored side doesn't’t go lean?
  7. I only have room for one gauge but I have dual exhaust. What can I do ?
  8. Where can I install the controller? What if it gets wet?
  9. I have the FJO controller connected to my non-FJO ECU (or datalogger) and the AFR on my LED display does not match the AFR displayed on the ECU - how can I correct this?
  10. What type of ECU can the controller be used with?
  11. How long is the O2 cable on the controller?
  12. Can I order sensor cable extensions for the controller?
  13. If I buy a controller kit today, can I upgrade it later?
  14. What type of PC do I need to use the datalogging feature?
  15. Where can I get the calibration curve for the controller's analog outputs?
1. 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)
2. 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!
3. 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: You will need to contact FJO Techsupport to determine if your controller has the ability to be upgraded. Because the new sensors use a different cable and require a different calibration, your unit will need to be returned to us.
4. How do I order an FJO product?
A: FJO products can be purchased from any of our Authorized Dealers listed on our web page.. Many of our dealers will have your selection in stock and can also provide application or installation services. You can also contact FJO Sales directly.
5. What is a NEW PRODUCT TESTER and how do I become one?
A: At FJO we are constantly improving our products. Before we allow new hardware or software features to be released, they must undergo extensive testing. The first stages of testing are all done in-house by our experienced engineers and technicians. Once we're happy with the development, we select a few "customers" to put the product through its paces and give us feedback. These enthusiastic shops and individuals are what we call "new product testers".
If you think you have what it takes to belong to this select group of individuals, please send an email with the subject "NEW PRODUCT TESTER". We will reply with an application form for you to complete.
6. I have dual exhaust but my ECU only has one input. How can I be sure that the unmonitored side doesn't’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!
7. 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.
8. Where can I install the controller? What if it gets wet?
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. 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...)
9. I have the FJO controller connected to my non-FJO ECU (or datalogger) and the AFR on my LED display does not match the AFR displayed on the ECU - how can I correct this?
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.
10. What type of ECU can the controller be used with?
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.
11. How long is the O2 cable on the controller?
A: The cable supplied with the kit is approximately 4 feet long. Since the controller is fully sealed it can be installed just about anywhere on the vehicle - even if it gets wet or dirty. There are also optional cables available in 8 foot and 12 foot lengths - perfect for DYNO installations.
12. Can I order sensor cable extensions for the controller?
A: If you require a longer sensor cable or a replacement cable, optional cables are available in 4 foot, 8 foot, and 12 foot lengths.
13. If I buy a controller kit today, can I upgrade it later?
A: YES! Optional components may be purchased at any time from your authorized FJO dealer.
14. What type of PC do I need to use the datalogging feature?
A: The PC software is supported on Win98SE, Win2K, WinXP provided that the hardware has a standard 9-pin serial port. For laptops without a serial port, a USB/SERIAL or PCMCIA/SERIAL adapter is required. Due to the wide variety of these adapters available, FJO cannot guarantee a specific adapter however, our testing has shown that USB/SERIAL adapters using the Prolific Technology PL-2303 controller chip function very well. Other adapters may also work - make sure you have the latest driver for your operating system.
15. Where can I get the calibration curve for the controller's analog outputs?
A: This information is included in the installation manual.
In addition, you can download a "correction factor spreadsheet" which will provide you with a custom calibration for your particular installation (takes into account "signal loading" by your ECU or Datalogger).
