stock wideband relocation


adosdrummer

Recommended Posts

I do have a lc1 that I use to tune with, but I don't keep it always in the car..

I tune other people's car with it and modified it to plug into the cig lighter for power instead of installing it into the car since it gets moved around a lot.

 

I know the stock wideband is pre turbo, If I install it after the turbo in the downpipe should I expect a little better accuracy? Will the computer play nice with the new location?

From what I've seen on here, yes, that's a better location for it (on the downpipe, before the cat if you have one). I guess the stock pre-turbo location sees high exhaust pressure, which can throw off the accuracy of the wideband sensor.

 

I assume that you deleted the UP cat if you had one?

Im putting in a wideband myself..eventually. from what ive gathered its good to have it around 5-6 inches down the dp. Some say 8-10 inches though. It just depends on the tuner. They get burnt out relatively easy, so how far you put it down the pipe can be crucial to the life of the sensor.

Hope this helps..

The factory 02 sensor is a narrow band sensor. I have an aftermarket wb02 in a Cobb down-pipe since there is a bung for an o2 sensor. It is a little close to the turbo, but mine has survived without issue for several thousand miles. Bosch o2 sensors require they be powered up at all times or they will become damaged.

having the stock one in place and simply adding a wideband should not cause any issues.

Stock sensor is a wideband, not narrow. It's just not very useful as a wideband for a bunch of reasons.

 

Call it what you want, but my point is that : You do not want to rely on AFR readings (accesport) to determine your AFR's, especially at wide open throttle. Some of the reasons are 1) readings are not accurate and 2) range of readings is more NARROW than with an aftermarket Wbo2 sensor.

Sorry to bump an 'old' thread..

 

But do you happen to have any pics of your cig lighter/temporary setup?

I wired my LC1 up for temporary install with a cig lighter plug last night

and wanted to compare/double check my connections before I plug it in.

 

My aim is to use this LC-1 for data logging with ATR for my new tune.

I had a bung welded in on top of my DP so both factory O2's are staying

put and untouched and I don't want an interior guage.

This is what I ended up at:

Figured why not with the box.

My wiring goes like this:

1) RED 12v SUPPLY wire on LC-1 to + blk/wht stripe wire on cig lighter adapter.

2) One side of the momentary push button and the red anode wire of the LED connected to the BLACK calibration wire of the LC-1.

3) Other 'ground' side of momentary push button and black cathode wire of the LED, along with the BLUE heater ground and WHITE system ground of the LC-1 go to the - solid blk wire on the cig lighter adapter.

 

And that completes the circuit. ???

Because my brain is trying to tell me that the way I have wired now, wouldn't the LED complete the calibration wire circuit without pressing the button?

 

I guess really it's just the LED anode wire that is throwing me off.

I dug thru the search results but couldn't find anything directly relevant so wanted to post for future use.

It works, it works!

Well, that is to say that I got it programmed with the laptop, calibrated the heater, and did a free air calibration without any error lights at least :) turbo is all primed up and ready to be fired!
