my plxm300 wideband o2 is coming in tom. and everything on my turbo set up is complete but, im wondering wheres the best place to mount the o2 sensor for the m300 kit. and do you have to run the stock o2 sensor?

i remebering seeing a thread about this earlier but there was various answers.

so where should the stock o2 sensor go?

where should the o2 sensor from the m300 kit go?


thanks in advance everyone

 

you can set it up to run WITH your stock o2, using the wideband for display purposes only, or you can remove the stock o2, use a resitor included in the plx package to simulate the o2 heater circuit, and simply use the wideband as your main o2.

its really up to you and what you are running for management.

oh ok thanks for the responce. im going to be using the wideband as my main o2. im going to be running uberdata, (i posted on the uberdata forum but it moves slow) has anyone had any problems with the plxm300 and uberdata?

 

up for some info

 

i'm not familiar with uberdata, so i can't comment on that.
but in hondata, there is an option to disable the o2 heater which will make install a breeze- no need to instal the resisotr for the heater. also, you can set it to run a simulated narrow band circuit, or to run constaly in closed loop (or is it open- i always confuse those two... basically, when it runs its set map that you burned regardless of what it is reading)

thats open loop.

just to chime in on what aem says, 36" away from the exhaust port. mine is right in front off, just off to the side of my factory o2.

 

i think plx saids anywhere from 12-18"

 

i have a question, im in the process of recieving my downpipe so i dont know how long downpipes generally are, but im wondering who on here is running open downpipe and if i weld the o2 bung around 12-18 inches from the turbo how far along the downpipe is that? i heard if its to far along the downpipe it throughs all of the signals out of wack?

I made my own DP and ran it here:



It read the readings just fine for me. It will be wack if the 02 sensor is too close to the end of the DP becuase fresh 02 WILL interfere. It doesn't matter where you put the 02 sensor long as it isn't too close (12") and better the farther it goes becuase the 02 sensor will last longer due to the difference in heat. just not too close to the exit of the exhaust

so if i understand correctly i cant mount the sensor on the hf manifold ?!

 

Just some info: Uberdata does have the "o2 heater disable" option as well as the "closed loop disable" option. I tune cars w/ closed loop disabled. I also run an Open DP on my car (haven't got pulled over yet ) and I have the wideband bung about 8 inches from the end of the DP and about 10 inches from the turbo outlet.

what wideband kit are you running? how long have the o2 sensor lasted so far running it 12" away? how long do the sensors generally last from that far?

 

I have the PLX m 300 like you. It works flawlessly. It look slike it's about 20" away to me. I don't know how long it will last. Anyone know the average life of a wideband?

are you running open DP or a full exhaust?

which cable are you using to transfer the datalogs to your laptop? also which datalogging program are you using?

anyone have any truth on how long the sensors last? i plan on welding the bung about 13-14"s away

I tuned on open DP and now have full custom exhaust out the side of the car. Quiet and cool .

I use Uberdata and I am inputting the wideband signal directly to the ECU. I am using the Nokia Data cable in my USB port for my laptop. I can do lambda logs of each cell values AFR making it really easy to tune.

do you know the exact name/model of the cable? do you how long or can you estimate how long your DP is?

 

Just to add, one of the great things about the PLX unit, it uses a Bosch sensor, commonly found in Volkswagens and Audis.. These sensors run about 30-40 bucks at just about any auto parts store... They are expected to last approx. 30k miles, but they have been know to last longer, since they are manufactured with longevity in mind, being an OEM sensor... Although, the use of race gas could also shorten that life expectancy.... I use mine daily, as I have for about 3 months now, and I just frequently clean it with some carb cleaner to prevent excessive carbon buildup, and toss it back in...

Just my $.02

how far after the turbo inlet is your wideband sesnor? are you running an open dp?
