Ralph - I'd very much like the 02 to work but to date the best I can get is a reading at idle - as soon as I advance the throttle to TO power the display either shows a fault, or zeros. I have the bung at 11:00 oclock, its well upstream of the end of the pipe, and several inches downstream of the 3-1 merge. I have tried 2 different Bosch sensors and 2 different controllers (both 14 point 7).

Dave Anders suggests that he had the same issues at first and it was traced to a leaky slip joint upstream of the bung.

I do have the data logger but I have yet to plug it in, figuring that the O2 is not tracking there either. Can it show a fault on the SDS display but still log properly in the ECU?
