Wideband O2 Sensor

[86 TR]

Who sells a wideband 02 sensor?? Can you leave the stock 02 where its at.
I'm still running the stock computer, maf, 02 etc. on my car.

Can you tune alot better with this wideband 02?? Does it run as a stand alone unit or will it work with my scanmaster I currently have? Do I really need one or just save my money?

Somebody told me to get one and be able to tune my car alot more accurately??

Thanks.

Many vendors on this board sell WB's. You could check with Cottons, Full Throttle, or Harline.

Innovate WB's are good, and will run in the $350 range. You will be able to tune more accurately with one, and it is a stand alone so your Scanmaster will not factor into it.

You also will leave your stock narrow band O2 in place, and will have to weld a new bung further down on the DP. HTH, Brian

also, the ....

placement of the bung is critical to the longevity and accuracy of the 02 sensor. I believe the majority has agreed to a minimum of 14"from the turbo and located between 10 & 2 o'clock. This helps to protect the sensor from heat and raw fuels.

Some WB setups have data recording ability, as well as a NB output.
You wire the NB to the ECM, for a "replacement" signal, and no longer use the OEM sensor.
I use the PLX product, and have had good results with it.
I'd suggest buying a system that uses the BOSCH sensor, as the NTK replacement sensor can get pricey...[Unless you have a loooonnng deal on them, as some may.]

Look here:

As for WB vs NB?? No comparison! The NB is not a good tuning tool, as it's accuracy diminishes as the A/F gets away from 14.7:1 ....

Back under my rock..

The Innovate system uses a Bosch WB sensor and can be configured for the NTK sensor. Chuck's recommendation is good advice. Stick with a system that uses the Bosch sensor. Replacment Bosch sensors can be bought for $48 each (VW OEM sensor). NTK's are like $150-200 range.

The Innovate has data capabilities and software to download, view and graph the data. I've never messed with the data capabilities of mine, but it is a powerful tuning tool. No guessing what is going on (as long as the sensor is good).

Sensor placement is cricitical for accuracy and sensor life. The sensors need to be turned on and warmed up anytime the engine is running or they die very quickly. The sensor cannot tolerate any water condensation in the exhaust (thermal shock) and that is why you mount the sensor in the 9 to 3 O'clock position
A bung in the DP is the best place to put the sensor.

Wideband

I just installed my Innovate LC-1. I had 2 bungs welded in my down pipe. I moved the factory o2 to 3:00 and installed the LC-1 o2 at 12:00 two inches apart and about 12 to 14 inches from the turbo. I run a Gen2 with an Extreme G chip and set the A/F ratio to 11.4. Before I had the LC-1 I used the Gen2 to add more fuel because my o2's were too low or so I thought. Now I let the wideband add and remove fuel automatically. I gained almost 2 tenths and 5 mph on my first 1/8 mile pass. I did run my car rich so I would not have to worry about leaning out. The install was pretty straight-forward and now I can use the Gen2 to monitor various outputs. With the wideband, Gen2 and G chip there are a lot of tuning options to monitor and adjust. Find the right tune and you will improve your ET hopefully without damaging the engine. It does require some basic computer skills to navigate software.
