Wideband Oxygen sensor boss - where to find one

[Will ing]

As above

I've been speaking to a guy about getting my car mapped but he needs to get a boss made and weld into my exhaust, but, he is busy and it will take him a while to get a boss made.

so instead ofd wait for him i will try and get one he said it is M14 x 1.25, this seems really fine and small for a sensor.

I tried to source it on google - no luck then tried just a simple M14 x 1.25 nut, again no luck unless you want 500 off.

Does anyopne have any ideas or suggestions or do you think he has the size wrong?

BTW its for an emerald but no idea what his sensor is

thanks Will

you can buy them quite cheaply but your car has a lambda narrow band fitted and the wide band will fit into this narrow band hole once you remove the narrow band lambda but he should know this already ?
you may damage the threads or the narrow band when removing , you can use a special tool to remove it

Will,
good to meet you on Saturday, now I know why you were driving so sedately

You will get a boss from demon thieves here http://www.demon-tweeks.co.uk/products/ ... JETU690200

I have just fitted a Innovate motorsports LC-1 wide band lambda, I'm pretty sure a bunch of people will tell you they are crap, but mine is the new 6 wire model not the 7. Followed the Innovate and emerald instructions and it is working spot on. Had the Emerald in adaptive mapping mode for KH and looking at the injection corrections it certainly seems to be doing the business . So despite some reservations before buying it I can now recommend it. It's also available locally from Wallace Performance. So even if it does go tits up I can get it changed under warranty with out faffing about waiting for someone to post it from the other side of the pond.

There is a thread running for a PLX wideband that Shug bought and fitted. Looks a nice bit of kit but a hell of a lot more expensive, and no UK agent yet. FYI the LC-1 was £160 delivered but you can find it cheaper, I just needed it quickly.

Mike

Hiscot is right it will fit in the existing boss, however when I removed my narrow band the boss threads weren't in the greatest of condition so might need a tap to clean out the threads before fitting the new one.

Sadly I CBA to go look but I have a boss knocking around somewhere. Remind me tomorrow night when I haven't had a pint....

[hiscot]

my lc1 has also been fine but the plx is self callibrating and as i run target lambda its a nice feature to have
mine is the older 7 wire version , and as long as the grounds are right they are ok there was a faulty batch with a string of faulty ones and sadly that also looks to be the same with the six wire version
heres a quote
there are some problems with the early 6 wire lc1's, some lose their calibration and make the guage on the screen read from full lean to full rich and back again repeatedly, mine showed the same symptoms and is currently back with them for replacement (only if under 6 months old) loads of similar stories on the lc1 forum, i have purchased a plx device with guage and it is spot on straight from the box, the lc1 wont be going back on
make sure the lc1 has good grounds or it can read wrong
ps dont get any copper grease on the wide band sensor except a slight smear on the threads only or you can damage them

[Rich H]

My sensor was pre-lubed

My LC1 got stuck on Saturday too. Just froze at 14:1 until I reset it. I'm wondering if its the beginning of the end...

[Mikie711]

Touch wood mine has been trouble free so far, but it is early days. I have to admit the calibration schedule is a bit of a pain. Might see if I can get one of my Americian mates to bring some over. If anybody wants one drop me a pm and I will get a price.

[hiscot]

Mike my lc1 has been ok for over two years now and the free air calibration can be done with the sensor in situ even set up with a dash switch on over run down a hill if you have decel fuel cut , its not often it requires it either, but i am changing because my fueling is always controlled by the lambda therefore a self calibrating one should always be spot on
another reason is the dta now has a check box for the plx as well as the lc1 so hook up tick box and away

Will,
good to meet you on Saturday, now I know why you were driving so sedately

It was difficult to unleash the raw tallent that I have not yet discovered.

thanks for the info on the wideband sensor i think it is definately the way to go. Is it much of a job to wire into the Emerald - does it literrally just connect to the second RS232 on the emerald or am i being way to optimistic?

Hi Hiscot,

I spoke to you on Seloc a while back and and you suggested Ricky Gould for the mapping, however i have been told he is not operating any more. The guy I spoke to about doing the job was Jim King, not sure what other people think of Jim, seams a nice guy but that obviously doesnt tell me much.

Thanks Will

[Mikie711]

Will,
it doesn't wire into the spare rs232 plug you need to get some blades from emerald as it wires into the main ecu plug. It's still quite easy and I can give you a hand if you like. Have a look in announcements regarding Mr Gauld as he is indeed still operating all be it for someone else now.

[Will ing]

Thanks Mike might just take you up on that offer, just trying to find my Emerald user guide as i'm sure it mentioned installing a wideband in there

I assume you just bought this http://www.innovatemotorsports.com/xcar ... ctid=16169

BTW - the unit did come with spare connectors but i'm not sure how many - i had to run a spare coil feed from pin 11 from memory due to the wasted spark.

Found you post on Ricky Gauld i think i'll try to get booked in there.

Lastly if i have the LC-1 will he use this to map it, is it accurate enought?

[Rich H]

If you are buying new then go for th eone Shug/Hiscot found. LC1 does not have the best reputation.

But any wideband should be OK as long as its calibrated

[Mikie711]

Ricky uses an LM-1 for mapping which is just a hand held version of the LC-1, so if calibrated properly then yes it's accurate enough. It was his recommendation that prompted me to get one.
Waiting for the guys to get off the rig so I can see if I get PLX on the cheap, should work out about £100 instead of £200 . Might get one and see what it's like. Quite like the fact it's modular. However, the LC-1 is the one mentioned in the Emerald manual and seems to be working fine. Time will tell how reliable it turns out to be.
Will eventually switch back to open loop as will no longer need to run adaptive mapping as it should sort out the injection map over time.
Yes that's the one you get from Wallace Performance. Comes boxed with lambda boss, software, calibration lead etc etc. My only complaint so far is the leads for the controller are very long and make it look a bit untidy. You will need a 100ohm resistor to fit in line with the signal wire. You can get that from maplins or I have a few spare.

is the PLX one this http://www.plxdevices.com/products/sm/afr/ and is this all you need to buy as this is only about $200 so with shipping and tax should be about £150

I read in Shugs thread he bought a guage as well, is this really necessary as i assume the live adjustments screen will show this?

Will

[Rich H]

Gauge is a nice thing to have as it will tell you if somethign has gone wrong, for the ££ its worth it over a busted engine. the output form LC-1 or PLX is there so why not use it? If you can work a soldering iron you can make your own like mine in the Porker for maximum pikeyness (Bits were about £10):
