XX4me Posted December 4, 2010 Share Posted December 4, 2010 This question is directed towards a EFI vehicle that uses a narrow band O2 sensor to set fuel. Would the voltage values needed for the ECU and provided by the OEM narrow band sensor be the same if a wideband was substituted. In other words can a wide band be substituted for a narrow band to allow mapping without adding another bung? Quote Link to comment Share on other sites More sharing options...
Mekanix Posted December 4, 2010 Share Posted December 4, 2010 I can't answer your particular question but I did find these when I was trying to find a way to manipulate the voltage signal to the computer to get the right richness in that stupid lean burn 696. After I totalled up all the parts I came across it and it was just about the cost of parts minus the need to troubleshoot and find the right resistance. http://www.fatduc.com/compatibility.html Of course the same could be used on a BB. Someone with more electronics than I could find a way to use solid state circuitry to electronically get the signal you want if a wide band O2 sensor doesn't work.

cbrxxquad Posted December 4, 2010 Share Posted December 4, 2010 I got the answer,,,but forgot.. http://www.innovatemotorsports.com/forums/ should be able to answer in side somewhere. I don't have time to look for it for you right now, but, as I remember my innovate lm1 has an output to go to the OEM computer to simulate the narrow band voltage. Hope that helps.
