I think I may have toasted my PLX sensor. I was running a rich basemap and I've leaned it out a lot, and its still reading rich. I guess I might have gas or carbon buildup on the sensor, but its only been driven for about 30 miles.

You turn the IGN to the ON position and it reads 14.68-14.7, then after it warms up it goes from 14.7 to 10.0, then reads "Rich".

I don't know if all sensors will get retarded like that, but my PLX did. I'm hoping that running the car will burn off some of the stuff, but I'll figure that out as soon as I get my downpipe welded up tomorrow.

Damn, I wanted to get into tuning. If this sensor is blown I'm fucked.

thats why in almost any wideband designed you can set it up to output a constant voltage....then check the voltage in your dataloggin software....once they are calibrated to eachother...there should be any variances...if your using you eyes to see if your close...you comp is loggin fast enough

dataloggin w/ the narrowband is nowhere close to the same as the reg wideband...disbale o2...and run open loop....call it a day....thats why a wideband has 0-5v for thw wideband...and then 0-1v for narrowband simulation....you reduce the resolution by 5x....so get it tuned right w/ the wblin....then run in narrowband....id never be tuning my car w/ narrowband output...its perosnally not using the wideband to its full potential...

any sensor in free air should read extreemly lean....if its toasted go to vwparts.com and get one for $37.99...the part # is on wbo2.com

The PLX comes with 2 resistors. It says to run 1 resistor to the narrowband output and 1 to the wideband output, and then sodder them both into the ECU. That way your ECU gets the narrow band input it needs and your datalogging software gets the wideband input it needs.

Yeah, Lean in open air, but it reads rich. I ran the car and once I hit boost it read something around 11.5, so I think the VAC part of my map is very rich, while the boost portion is good.

I don't think the VW O2 will work with the PLX because the PLX has 6 wires and its own whack plug that it needs to use to connect to the sensor.

gayness...it shoudl work tho...almost all widebands support more than 1 sensor..but im not familar w/ the plx...

on a sidenote only 1 output should be wired into pin d14 at a time...if you tuning...the wblin output...closed loop the narrowband simulated...if you connected both im prety sure it wont work as it was intended....usually people make a switch setup...where one ways its wblin and the other its narrowband...so they can switch w/o dis/connectiing wires

I don't actually have them both wired, just the narrow band for now.

I agree with what you're saying about not having them both wired. I thinking the same thing. If you have the narrow and wideband putting out a "Lean" reading, it would be around 6v going in, instead of the 1v or 5v from either of them. (That's a theoretical voltage just for easiness of understanding)

 

Can you drive around with the LC-1? Also, can you place it in the stock's location (in the catalytic converter)?

Anyone running test pipes? I'd like to switch to a high flow catalytic--not necessarily a test pipe-- (want to start fresh with the wideband so it doesn't get dirty from all the junk in the stock cat). Any recommendations? It'd be nice if it has an O2 bung already welded.

 

yes the lc-1 is a widbeand controller just packaged in a cable...i doesnt feature any standlone dataloggin capabilities...but is designed to be used for standalone systems like crome, uberdata, neptune etc....and its pissssss cheap!
