its just what I was told.....I havent had any time to check into it....
I guess its not on all vehicles and teh person that told me didnt look it up for my car :shrug:

So your saying you should power the LC-1 from the fuse box (switched) or should there be a delay in turning that on so it doesn't have to undergo the cranking?

Is it ok to power the wb sensor off the stock 02 sensor wiring then or should I power that separately so that I can turn it on and off? If I didn't have the WB, wouldn't the stock 02 sensor be sitting there getting hot while I was dumping? Or is it because the WB is more sensitive than the NB?

Hope that makes sense.

I have it switched...thru the fusebox..so I can turn it on and off myself...
usually I turn it on..then crank the car....but it wont hurt to crank first and then hit the switch

I have mine in place of the NB...so for me wide and narrow are one in the same

what you want to avoid is long periods of it being on with no exhaust..or long periods of time with it being off while the exhause it hitting it...both these conditions lead to premature failure of teh o2....
so my switch is a good way to turn it off when just sitting and reading/flashing...or like when you stop to run into the store for a half hour cause you get a call from the wifey to pick a bunch of crap up on your way home.LOL

Purple,

Yes it is ok, you can power from the stock NBO2 sensor connector on the vehicle harness (be sure to pay attention and double check your wiring when you splice on the 4-way connector).

The problem is that there could be moisture/condensation in the exhaust, and if you first warm up the WBO2 sensor, then when you start the engine, all that moisture gets blown onto the hot sensor and damages it (temperature shock).

Also, it is bad for the sensor if you run the engine with the sensor powered off, this will damage it also.

What I do when I want to flash...
If the car's cold, I first start the engine and let it warm up for a few minutes.
Then I shut it off, and then do my flashing.

Scott has a switch wired inline, so he can turn off power to the sensor, this is very convenient...
but you have to really pay attention to not leave the switch in the wrong position.

Just wanted to thank both Soundengineer and Joecar for providing the info in this thread. I wired my LC-1 in place of the stock narrowband (using all four connections in the stock O2 harness) a couple of days ago. The instructions in this thread are more than adequate for a novice (like me) to wire one of these up. I had never touched a wb before and I do not have much of an electrical background. The LC-1 box itself tucks very neatly next to the shifter under the console, and all the wiring is well hidden.

bshell, thanks, and good work, way to go.

and my rocker switch is one that lights up when its in the on position..so its not hard to tell what position its in

I wired up the LM1 in the place of my nb02 and it worked great. Only issue I saw was it was'nt switching back and forth like the one on the other side. Car still ran good though, just wondering if I missed a wire or something.

joecar

That's a good way to do it, user friendly.

joecar

With the LC-1 programming application (runs on Windows), go in and check the tranfser function of Analog Out 1, and set it to Default; see if this works.

I think it was the analog ground connection I left loose, going to try to hook it up tonight and see what happens.

Ok, now that you guys have figured out part 1 of my hint i gave a while back in a previous thread. Efilive guys can turn on a setting in the pcm that will allow the computer to fully adjust fuel for you even at wot. The computer will use your wideband to set up fuel to what ever you command and it will be ACCURATE.

I missed that one sounds interesting.

Jesse,

What voltage/afr range should the WBO2 be programmed to be used with B4206 enabled...?

Joe

soundengineer

iTrader: (16)

BTW..we have this in HPT as well

joecar

What AFR/voltage points do we program our wideband to...?
Then just enable B4206.
Anything else...?
Can do this in any of MAF'd, SD, OL, CL...?

its a table that allows STFT correction in open loop.....
