Hello all. I have a duel exhaust system on an NA engine.
I am wanting to use an innovate lt-1 wideband sensor.
Is there a way to link the two pipes, or do I need to use two different sensors? One for each pipe.

 

Haltech has a dual band 02 sensor setup.
This is of course to be used if you run the Haltech Ecu and want to hook up the wideband to it for info..
If you are setting up that s5 for performance and intend to run an aftermarket ecu then I would go that way.
But Honestly if it is just a stock s5 then I would run one 02 wb sensor..on one pipe and save the whole headache.

 

you have several choices.

1. stick it in the rear rotor pipe and call it good.
2. tune it in the rear pipe, then put it in the front pipe, and make sure its the same.
3. add a second sensor.

i like to start rich, and lean it out until it stops gaining power, and then richen it up a tad. if you graphed this, it would have an ascending line, that flattened out, and you want to be near the top of the ascending bit

 

I like the idea of tuning the rear then checking the front.
Thanks for the input guys!
