Spec B Posted February 17, 2009 Share Posted February 17, 2009 The bung in the rear of the DP is a narrowband (not EGT)..it is used to skew the fuel trims at cruise. If you use that bung and remove the stock sensor the car will run uber rich during cruise. There is a way to remove the stock sensor and send a "fake" narrowband signal to the ECU, that way you won't need to add a new bung BUT the much easier solution is to add a bung..about 12"-18" away from the turbo and use it for your wideband.

Spec B Posted February 19, 2009 Share Posted February 19, 2009 FWIW, I just installed my LM-1 yesterday..I used the grommet on the passenger side (small round one) and wired everything to my glovebox. I leave the LM-1 in the glovebox, and powered it via the cig lighter in my center arm rest with the power running under the dash and into the glovebox. When I want to log, I plug in the tactrix and the analog cable out of the LM-1. Link to comment Share on other sites More sharing options...
Guest LGT-NY Posted February 19, 2009 Share Posted February 19, 2009 Cool. Why not just hard wire it though? Link to comment Share on other sites More sharing options...
Spec B Posted February 19, 2009 Share Posted February 19, 2009 I probably will eventually..but the LM-1 is a portable unit and uses a lighter connector to power it...I did not want to go through the trouble of finding a power source, splicing it, ect...

Guest LGT-NY Posted February 19, 2009 Share Posted February 19, 2009 Gotcha... Sounds like a nice setup. Enjoy. Link to comment Share on other sites More sharing options...
Scrad Posted February 19, 2009 Share Posted February 19, 2009 Spec, so your red wire had a cig lighter adapter? I bought mine used, so it didn't have that. Do you mind taking some pics of how you installed it, because this sound like the exact way I want mine installed. Thanks, Chad Link to comment Share on other sites More sharing options...
Spec B Posted February 19, 2009 Share Posted February 19, 2009 Yeah..the red wire had a cig lighter adapter, it plugs right in. I will take some pics..either tonight or tomorrow. It was a pretty big PITA to get the wire in from the engine bay to the glove box..I had to actually remove the grommet and reinstall it. But now that it is complete it looks real clean IMO.

Spec B Posted February 20, 2009 Share Posted February 20, 2009 Okay...not the best looking install in the world, but i think these pics might help. 1 - This is the o2 hookup and run against the chassis 2 - Here is the grommet I used 3 - LM-1 in glove box (wires still need to be tamed) 4 - Power out of center armrest Here is an engine bay pic for general reference..I used the grommet on the left of the photo.

j255c Posted February 20, 2009 Share Posted February 20, 2009 I dont remember where i read this but having it sit at a 90degree angle is not good. Maybe im wrong. 06 TB EVO IX SE stock turbo monster subaru hater Link to comment Share on other sites More sharing options...
Infamous1 Posted February 20, 2009 Share Posted February 20, 2009 The LC-1/LM-1 is recommended to be installed at the 3 o' clock position. Link to comment Share on other sites More sharing options...
Drew888 Posted February 20, 2009 Share Posted February 20, 2009 I'm asking here because it seems the all knowing of things WB02 are here in this thread. I need a tune, and soon to seriously bug infamous for it, and I need a temp WB solution just for the tune (I have a Cobb dp, btw). I will be removing it afterward (only to maybe redo it if I can get it to integrate to the HKS Camp II I'm seriously considering). What is the easiest way to get this done? PM me if you like. Thanks, Shamar, dude...I neeeed to get on your calendar! [URL="http://legacygt.com/forums/vbpicgallery.php?do=view&g=1586"VbGallery/URL] Link to comment Share on other sites More sharing options...

Thanks, Shamar, dude...I neeeed to get on your calendar! Well I have my own wideband for road tuning and you have a Cobb dp with the bung in the bellmouth so you are find. Once I get done scaling your setup a wideband would just be your personal choice to keep an eye on things. Link to comment Share on other sites More sharing options...
Spec B Posted February 20, 2009 Share Posted February 20, 2009 The LC-1/LM-1 is recommended to be installed at the 3 o' clock position. Wait, is mine installed wrong? I tried to approximate the JDM location (T7). Reference below: http://i141.photobucket.com/albums/r69/mickeyd2005/untitled1.gif Link to comment Share on other sites More sharing options...
mickeyd2005 Posted February 21, 2009 Share Posted February 21, 2009 There is nothing wrong with the position. The 3 o'clock position is recommended relative to a pipe that is horizontal. Link to comment Share on other sites More sharing options...

mickeyd2005 Posted February 22, 2009 Share Posted February 22, 2009 The only thing I would have done differently is put it on the driver's side. However, the bung is so far from the bellmouth that it won't make a difference. Link to comment Share on other sites More sharing options...
Spec B Posted February 22, 2009 Share Posted February 22, 2009 Yeah...I placed it on the passenger side for easier install/access. Link to comment Share on other sites More sharing options...
rtbrjason Posted February 23, 2009 Share Posted February 23, 2009 Yeah...I placed it on the passenger side for easier install/access. Just curious, why did you choose the LM-1 over the LC-1 or AEM if you did a permanent install? I'm debating which way to go with this myself.

Spec B Posted February 23, 2009 Share Posted February 23, 2009 I heard that a lot of LC-1's have died prematurely..that and there is a fairly complicated wiring and calibration procedure with the LC model. The LM-1 is a little more expensive, but the wiring is super simple and so is the initial calibration and of course, it is mobile. I was also looking at the AEM..but the LM seemed like the better fit. Link to comment Share on other sites More sharing options...
caramall2 Posted February 23, 2009 Share Posted February 23, 2009 Position: So could I be getting inaccurate readings using the 12 o'clock position on the bell mouth where Cobb puts their bung? I know Innovate seems to recommend against this (being too close to the turbo). Why I ask is I'm working hard on some AFR tuning and I keep getting slightly lean readings. This could be truly lean, but just wondering if the position might be causing problems. Link to comment Share on other sites More sharing options...
Scrad Posted February 23, 2009 Share Posted February 23, 2009 If your DP has a Divorced Wastegate, like my Invidia does then I could see inaccurate readings if you put it on the passenger side of the bellmouth. But if it doesn't I don't see why the 12 o'clock position would matter. Link to comment Share on other sites More sharing options...
Spec B Posted February 23, 2009 Share Posted February 23, 2009 +1 From what I have read, the position of the sensor (12 o'clock) will not skew your readings...assuming you are running a non divorced DP. What the bigger concern is is the heat and longevety of the sensor itself since it is so close to the turbo on the cobb design. With that said, there are many, many folks running their O2 sensor on that spot with no o2 sensor problems. Link to comment Share on other sites More sharing options...
LittleBlueGT Posted February 23, 2009 Share Posted February 23, 2009 FWIW I ran my WB in a WRX last week, the position of the WB sensor was about half-way down the DP. The observed AFR was very smooth. It would show 11.2 for about 1/2 a sec, then 11.1 for half a sec, etc..... In my car (COBB DP) it bounces around a lot more, 11.2, 10.8, 11.1, 11.0, 11.4 all within about 1/4 sec. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!! Link to comment Share on other sites More sharing options...
