Wideband

[Roberto Mercado]

What are normal reading for a wideband. Recently had my cam install

That is a tough question. Your tuner should be able to tell what you want to see at certain times.

You could see anywhere from 9 to 19 depending on what is going on when you are watching the gauge.

Ah i see thanks

14.7 while cruising is what you should see. When WOT will be lower of course.

The wideband sensor is a great tuning aid and an important tool to protect your engine from going boom!

It's usually in my experience used to tune for 50%-WOT and conditions where the fuel maps/tables are applied in open loop mode.

Make sure you've researched proper placement of the probe and orientation in the pipe so it doesn't accumulate moisture, and you're getting an accurate reading.

My experience only in working with Shawn at hemi-fever and Jay Greene is:

NA motors/cammed-target is about 12.5

For supercharged/power adder setups, the target is about 11.5

What a good tuner is looking for is a Wideband reading and fuelling that protects the motor by having enough fuel to cool the cylinders, while not being overly rich and leaving HP on the table. It's a delicate dance! This is what separates the good tuners from the bad.

Do you have any advice on placement?
My understanding is drivers side, up from the cat and at a 45 degree angle.

So I'm not the expert on this, but from what I've read you want it about 12-18" from the collector on headers (I'm running ARH LT Catless). I put mine right between the front and rear O2 sensors.

On CATALYTIC CONVERTER equipped vehicles:


Install the oxygen sensor’s **** upstream from

the catalytic converter (a **** and plug is

included in the LC-1 kit). Any decent muffler

or exhaust shop can do this for you. The wide-

band oxygen sensor is then installed into the ****

to take a reading. (Insert the plug into the

**** when not in use).

The **** must be installed in the exhaust pipe

at the side or on

top, NOT on the bottom of the exhaust pipe

.

Best position is between 10:00 and 2:00 position.




On NON-CATALYTIC converter vehicles:



You have the option with non-catalytic cars to also use a **** as described above. Use of a **** is the preferred method for mounting the 02 sensor for both catalytic and non-catalytic cars.





On TURBO CHARGED vehicles:


Install the **** downstream from the turbo before the catalytic converter. The high exhaust pressure before the turbo interferes with the lambda measurement and the high exhaust temperatures encountered there can damage the sensor.






Do NOT install the **** below the 3 o'clock or 9 o'clock position.

Condensation can form in the exhaust pipe and permanently damage the sensor.

6 o’clock is the absolute worst position to mount the sensor.

Appreciate this. I get it.

Thanks this is essentially what I understood. I'm running Kooks long tubes with the cats and will be handling the AFR gauge next week.

Cool. I shamelessly copied it from another website, glad it was useful

They look virtually identical to the instructions that come with an AEM wideband,so i'm guessing somebody else copied them before you James,lol

Mike has a video of where the wide band should roughly go if you have cats.
