Homer Posted April 28, 2006 Share Posted April 28, 2006 Following Lucifers AEM wideband gauge group I could do with a couple of pointers fitting the sensor. 1) On the CW decat pipe I have the flange for the sensor is at the far end of the 2nd decat pipe (around 5ft from the turbos). According to info on the forum this seems to be non-optimal, though I’m sure Chris pout it there for a good reason. Is it recommended to use this mounting point? 2) If this point is to be used are there any good places to route the wire into the passenger cabin from the rear? Its not long enough to go in through the normal point in the front. Cheers Quote Link to comment Share on other sites More sharing options...
Ian C Posted April 28, 2006 Share Posted April 28, 2006 Non optimal?! It's the recommended distance away from the turbos, by AEM themselves I had mine fitted in that place on my CW decat pipes, and copied the mounting location for my BL 3" pipe. The O2 sensor should sit right under your gearstick, you can route the wiring up through the rubber boot into the transmission tunnel area -Ian Quote Link to comment Share on other sites More sharing options...

Jake Posted April 28, 2006 Share Posted April 28, 2006 I don't have a CW decat pipe so I'm going to have to weld in the supplied bung. Does anyone have a pic of the bung position on a CW pipe so I can get it about right? Thanks Quote Link to comment Share on other sites More sharing options...
Ian C Posted April 28, 2006 Share Posted April 28, 2006 I'll be under the car again sometime next week so I'll try and get a piccy for you -Ian Quote Link to comment Share on other sites More sharing options...

SupraJames Posted April 28, 2006 Share Posted April 28, 2006 I am right in saying the position for the wide band sensor would be very close to where the narrow band sensor is on a UK spec..? there is one flange in my decat pipe already.

Jake Posted April 28, 2006 Share Posted April 28, 2006 No James. The AEM instructions say to mount it at least 36" downstream from the turbo Quote Link to comment Share on other sites More sharing options...

SimonB Posted April 28, 2006 Share Posted April 28, 2006 There's also a pretty big rubber grommit almost under the passenger seat which is what I used to route the wires as it comes in in a handy spot for the ECU etc. Quote Link to comment Share on other sites More sharing options...
Jake Posted April 28, 2006 Share Posted April 28, 2006 Any good? Thanks mate Blimey that's at way more of an angle than I was planning on. Won't the AEM sensor hit the car with it like that? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 28, 2006 Share Posted April 28, 2006 I have welded in a bung into my decat pipe in the same position as the CW one, after experiences with overheat on my old S14 i thought i'd play safe! oh and if you use the same place, then if you pull the carpet away from the transmission tunnel on the passenger side you will find a blanking grommet that is just in the right position, the hole is just big enough for the sensor and you can punch a hole and slit the grommet so the lead fits just right.

Soonto_HAS_soop Posted April 28, 2006 Share Posted April 28, 2006 Thanks mate Blimey that's at way more of an angle than I was planning on. Won't the AEM sensor hit the car with it like that? No, because he has the second decat pipe upside down. It actually sits at slightly below the 3-9 o'clock suggested angle. Quote Link to comment Share on other sites More sharing options...
Homer Posted April 28, 2006 Author Share Posted April 28, 2006 Thanks mate Blimey that's at way more of an angle than I was planning on. Won't the AEM sensor hit the car with it like that? No problem. The sensor is now fitted and its fine, no where near hitting anything. The angle is about about 30-35 degrees off horizontal.

chilli Posted April 28, 2006 Share Posted April 28, 2006 hmm my double decat from whifbitz has the bung a bit further up the pipe I think (need to check though) and I'm not sure of the angle on it. Anyone had experience with these pipes? its a 2.5" just like a CW pipe, but maybe I need a second bung welded in lower down to be safe. What happens if the guage is at the wrong angle, doesn't read properly or has a shortened life? Quote Link to comment Share on other sites More sharing options...
Homer Posted April 28, 2006 Author Share Posted April 28, 2006 The manual (now i've read it!) says that for turbo cars the sensor should be greater that 36 inches from the turbo and the angle from horizontal should be a minimum of 10 degrees. So long as it exceeds these it should be a okay. Quote Link to comment Share on other sites More sharing options...
chilli Posted April 28, 2006 Share Posted April 28, 2006 hmmm I think mine is more like 24" but I havn't measured it yet, will do tomorrow. Think the sensor would come out fairly horizontal so that might might be ok, 10 degrees is pretty tight though, some hills are steeper than that lol Quote Link to comment Share on other sites More sharing options...
Sharpie Posted April 28, 2006 Share Posted April 28, 2006 What happens if the guage is at the wrong angle, doesn't read properly or has a shortened life? Just for info: Innovate Motorsport AFR info states that if you install the bung below the 3 o'clock or 9 o'clock positions then condensation can form in the exhaust pipe and permanently damage the sensor. So, 6 o'clock is the absolute worst position to mount the sensor. Best place for the sensor according to Innovate is between 10 to 2 o'clock. The don't state a distance from the turbo to install the bung but, state 'downstream' of the turbo's and the max temp should not exceed 500 Deg C at the bung or you have to fit a heat sink.

chilli Posted April 28, 2006 Share Posted April 28, 2006 cheers Peter. arse, I have the feeling I might be best with a new flange in the right place and angle, don't really want the sensor to fail prematurely. I'll take a look tomorrow to be sure but looks like I'll be taking a trip to one of the experts to get a new flange welded in, might even just get the whole thing fitted in that case, normally like to do stuff myself where I can but I can't weld the flange in. Any recommended fitters not too many million miles away, in the south east? Quote Link to comment Share on other sites More sharing options...
Ian C Posted April 28, 2006 Share Posted April 28, 2006 Hmm, mine isn't at that bend, it's at the next one - that's a CW setup? -Ian Quote Link to comment Share on other sites More sharing options...

The bung is exactly where you said it was - just below the shifter. The left side of the pic is the side that connects to the cat-back.

The left side of the pic is the side that connects to the cat-back. hahaha ooops I knew that of course I always envisage left as front and right as rear because mentally I'm stood looking at the passenger side with the front of the car to my left as that's usually how I'm looking at it in the garage... Anyway, a piccy of mine in situ is below. -Ian Quote Link to comment Share on other sites More sharing options...
Sharpie Posted May 3, 2006 Share Posted May 3, 2006 What do you do with the sensor when it's MOT time ? is it happy just being tied up out of the way for the day ? Quote Link to comment Share on other sites More sharing options...
