I have a Dynojet Commander wb afr guage sitting behind the Pacesetter y pipe.

I'm planning a change to full dual exhaust and am wondering about the wb. Can't mount it in both pipes so ??????? Settle for a reading on one bank?

 

I guess. I would say buy another sensor so you can have a toggle switch and alernate between the two's sensing lines but with my innovate you have to calibrate the heater circuit and sensor when you install a new one.

 

..... or buy another one and have two guages.

 

I have been reading up on this as I am in the same boat. So far I gather that the WB should be on the passenger side because it is always the leaner of the 2. Cant say why, this is just what I have read. That doesn't really check since #7 is on the drivers side and it's the cylinder to go lean (first hand knowledge on that ) Also, I read that it should be before the cat. I'm only going to run one WB. Probably on the pass side. I will research more about where to place it as the time draws near. And I'll be on this thread for some expert opinions.

 

Might wanna ask Sport side. I know he has duals but im not sure if he has a wideband or anything like an afr gauge hooked up.

 

My tuner is now doing wideband street tunes, he told me get a bung before the cat on either side. Not right next to the cat, but a little distance from the collector. Mixture I guess.

 

My WB came with a bung to weld into the pipe. So I will have 5 O2 sensors I guess. If anybody actually has this set up Id like to see pics and get measurements from the cat to the WB O2.
