bucketep91 Posted May 17, 2013 Share Posted May 17, 2013 Went to fit my wideband today but if i take the sensor 36 inches away from the turbo(as per instructions) it would be in the middle of the back box!Surley i cant have it in the box? Any ideas? Quote Link to post Share on other sites
Socks Posted May 17, 2013 Share Posted May 17, 2013 Guidelines... Id just pop it in the pipe a few inches from the backbox if it was me... Cant effect readings that much surely.... You havent got much other choice either... Quote Link to post Share on other sites
AdamB Posted May 17, 2013 Share Posted May 17, 2013 It's not so much the readings that effect it, its the lifespan of the sensor. Quote Link to post Share on other sites
bucketep91 Posted May 17, 2013 Author Share Posted May 17, 2013 Thats what i was thinking adam. Id have popped it right in at the tail pipe but its gonna be a toght squeeze behind the front bumper i dont want the sensor on the outside of the bumper for obvious reasons lol Quote Link to post Share on other sites
AdamB Posted May 17, 2013 Share Posted May 17, 2013 You could drill a hole in the tip and fit it in there, but problem is with that like you say is the bumper. If you can angle the sensor you may get away with it if the tip doesn't stick too far out. Quote Link to post Share on other sites
triple j Posted May 17, 2013 Share Posted May 17, 2013 It would be best to weld the bung in just before the back box, dont put it in the box because there could be baffles in the way. Quote Link to post Share on other sites
TurboTobz Posted May 17, 2013 Share Posted May 17, 2013 Surely in the tip it would be inaccurate? I'd put it before the box IMO Quote Link to post Share on other sites

mikey4410 Posted May 17, 2013 Share Posted May 17, 2013 my wideband sensor probe(followed the instructions) said to to put it x amount from turbo,it ended up just under gearbox. middle box on is not right. Quote Link to post Share on other sites
bucketep91 Posted May 17, 2013 Author Share Posted May 17, 2013 Its a side exhit exhaust mate, comes out the front bumper. Cheers guys ill have another look tomorrow at some point:( Quote Link to post Share on other sites
AdamB Posted May 17, 2013 Share Posted May 17, 2013 Surely in the tip it would be inaccurate? I'd put it before the box IMO Why would it be inaccurate? How do you think tuners use their widebands? They shove the probe up the tailpipe. Tbh providing its not going to be providing a signal to an aftermarket ecu like a standalone then I wouldn't really worry too much where it goes, but where ever it does go it may shorten the lifespan of the sensor.

TurboTobz Posted May 17, 2013 Share Posted May 17, 2013 Fair point, but are tuners widebands designed to be at the rear? I'm only thinking theoretically hence the question mark, but the way I see it it's not only measuring what's in the exhaust but atmosphere too? I'm probably wrong, I know you know what your on about don't take that the wrong way. Quote Link to post Share on other sites
TurboTobz Posted May 17, 2013 Share Posted May 17, 2013 http://www.vems.hu/manual/html/ch09s06.htmlTake a look at Second paragraph Quote Link to post Share on other sites
AdamB Posted May 18, 2013 Share Posted May 18, 2013 Mm true, although I would expect the exhaust gas to be exiting the pipe to be of a greater pressure than atmosphere. I think the exhaust is so short anyway it will be a problem no matter where it goes lol. I would possibly shove it in before the back box but actually in it with the sensor pointing down slightly.

TurboTobz Posted May 18, 2013 Share Posted May 18, 2013 There's two ways of looking at it, but I do think before the backbox is the safest bet! Quote Link to post Share on other sites
bucketep91 Posted March 1, 2014 Author Share Posted March 1, 2014 Going to get this welded in before the back box, will it affect the readings or just the life of the sensor? Dont mind if i have to change the sensor after a while but dont want to have dodgy reading! Haha Quote Link to post Share on other sites
richardc9052 Posted March 1, 2014 Share Posted March 1, 2014 It wont shorten the life span that much and the replacement wideband sensors arent that expensive, its the name, controller and gauge you pay for. The sensors themselves are just Bosch units. Quote Link to post Share on other sites
bucketep91 Posted March 1, 2014 Author Share Posted March 1, 2014 Yeah i thought that mate, just want to know if it will give me false readings. If it does ill just use it on my oter starlet Quote Link to post Share on other sites
TurboTobz Posted March 1, 2014 Share Posted March 1, 2014 Lifespan of sensor due to exhaust gas temps doubt you'll notice much difference as your not overly close the the heat source.The bosch sensor makes up 50-60% of the costs of most kits they're not exactly cheap but I really doubt you'll see much difference in lifespan Quote Link to post Share on other sites
