1992 318 Magnum dual exhast question. - 01/08/11 09:29 PM

What to do with the o2 sensor? The truck has true duals , no cat, o2 sensor only on the right side. and dynomax superturbos. The check engine light stays off . It runs decent. Im just curious if this is something that works or am I handicapping it by running it this way. Will the o2 sensor read close enuf just from the one side? Or should it have a y-pipe to work properly?

Thanks!

You should put a Y pipe in it if it only has 1 o2 sensor unless theres some way to modify the computer so that you can have it read a second sensor.

Right now the bank that doesn't have an o2 sensor could be running super rich, super lean, misfiring, etc...and you would have no idea.

99% of the time, one O2 (in either bank) will be fine. (this is also the way the factory 360/390HP SMPI crate conversion is setup up).

Maybe I'm missing something but how would the computer know how rich or lean the other bank is running, especially on a smpi engine?

It assumes nothing bad is happening to only one side and treats them both the same.
