Thread: WBO2 Help

    Default WBO2 Help

    So I have a slight problem. I'm not to sure what I should do for purchasing a new WBO2. The one I have in my car is currently shot, so I thought about buying a new WBO2 sensor that goes along with the Holley controller I have. But for not much more I can get something like this: http://www.aemelectronics.com/?q=pro...ntroller-gauge, which would allow me to see the AFRs for say when I'm just driving around and don't have the computer open. Normally it'd be an easy choice and just go with the newer piece of tech that has a gauge with it, but I saw a post that Danny had posted stating how to install a LC-1 with the Commander 950 Pro. It mentioned something about how the LC-1 responds too fast and that you have to go into the setting and turn it down, which I'm not to sure you can do that with the gauge I have posted. Any suggestions?

    Thank you for the response, but I feel it still doesn't answer my question. Is it worth just buying another another WBO2 sensor for my already existing Holley WBO2 controller, or spend $50 more and get a newer WBO2 controller that also serves as a gauge and comes with a newer WBO2 sensor and if I'd be even possible to use that newer WBO2?

    Which WBO2 sensor kit do you have now, and is it integrated with the C950 ECU (Closed Loop)?

    At the moment, I have this kit: https://www.holley.com/products/fuel.../parts/534-197, which is installed & working with my ECU, but it needs a new WBO2 sensor as this one is currently shot.

    So contact Holley and purchase a replacement Holley 534-198 WBO2 sensor. And if you want a WBO2 gauge, purchase the Holley 534-200 C950 WBO2 Gauge.

    I think I was making this more complicated than it had to be. Thanks!

    I have a question about the Bosch/NTK WBO2 sensors that are used with Holley's HP EFI or Dominator ECUs. Can someone tell me which wire is closest in function to the narrowband vs wire which supplies an ECU with a voltage signal? Is it the Vs+ wire or the Vs-/Ip- wire? I'm pretty sure it's one of these two, but I'm not sure which one.
