Title: Possible to use external WB controller 0-5V as source for VEMS WB info and EGO?
Post by: NOTORIOUS VR on November 01, 2013, 09:27:22 PM
Just wondering if it is at all possible not to use the internal WB controller of the VEMS, and use say an AEM UEGO gauge with the 0-5V output connected to VEMS analog input and have the ECU use that as source for WB02 info and EGO correction?

Thanks!

I understand that for the wide band o2 sensor it is not a direct voltage measure as for a narrow band but that the measurement is obtained from the value of the feedback current which is necessary to maintain  a certain set point of voltage cell despite the perturbation due to the exhaust gas.
So I do not think it is possible

Why would you do that ?


The sensor is cheap , and it works great

I would never do that.  But I wanted to know for a customer of mine.

Using an external wideband as input is not supported, since we have internal dual wideband controllers onboard.
