Author Topic: O2 sensor woes.... (Read 5627 times)

Offtheclockuk · « **on:** October 27, 2016, 12:49:25 »

Hi chaps,
On my quest to return my k2 1000 back to the twin exhaust setup I found a cheap centre section exhaust in the states and duly bought it.....

I've only just realised on inspection that the us DL1000 has no o2 sensor in the system so the hole is blanked off,

Is there a way to remove the o2 sensor from my bike and run with no errors so I don't have to try and make the sensor fit?

Thanks in advance..... particularly hoping greywolf sees this as he's good at this kind of thing haha

Ebay search "o2 eliminator" and your bike model.

Only throws up one for the 650, are they supposed to be the same?

or just cut your losses

No cutting of losses till all cheaper methods are exhausted (pun intended)

I couldn't find any O2 connector blank for my K7 and ended up just disconnecting it and removing one of the wires in the ECU to stop any error codes coming up on the dash. Your K2 uses a different ECU to my K7 so you'll have to do so research on the internet to find out which wire to pull.

How about this bad boy? http://www.ebay.co.uk/itm/304-Stainless-Steel-Exhaust-Lambda-boss-Nut-Weld-on-M18-x-1-5-O2-Oxygen-sensor-

Check that it's the right size before you order. Drill a hole and weld it in. If you don't have a local welder, pop over t'hill and I'll stick it on for you.

Great idea! I was hoping to fit it tomorrow as my new cans are at work waiting for me.

I might give it a week and take you up on the offer though, thanks very much ????

Plan B.

You have a local hero TallPaul, he may be willing to help with this if you struggle.http://www.v-strom.co.uk/smf/index.php?topic=13997.0 it's just a resistor to enable you to junk the O2 plug with out any codes. Save £'s.

Can't you just run it without the Lambda & live with the fi light on for a while?

greywolf · « **Reply #10 on:** October 28, 2016, 16:16:30 »

Running with an FI puts the engine in limp home mode, running too rich, wasting fuel and carboning up engine internals. It will also prevent any other problems from being noticed. Vees and Wees don't have Lambda sensors in the USA, as the lack of a bung in the USA part indicates, so I don't know much about them.

Tallpaul to the rescue haha! I'll look into the resistor option cheers buddy.

Hondaman · « **Reply #12 on:** October 28, 2016, 17:24:05 »

Does it actually put it in limp home mode, ie reduced power or just show the fi light?
Many bikes run fine with lambda (and other non critical sensors) disconnected & simply run a stock default map (and fi light) ie the bike runs fine, if not optimally.
I'm not sure if wee/vee's are the same however.

Offtheclockuk · « **Reply #13 on:** October 28, 2016, 17:27:59 »

Hondaman that was indeed an option I considered haha!

Greywolf, what would be the wiring/ecu differences that allow the US vees run without the lambda?

If I pop out the signal (grey) wire from the lambda plug the bike runs without any fi light on the dash but I haven't ridden it yet to see if it's actually any different.....

I wish I was smart enough to figure out how the lambda is integrated in the uk system and how it affects the bike with no reading from it!
I guess maybe the ecu just has a default map that gives basic fuelling without it?

greywolf · « **Reply #14 on:** October 28, 2016, 18:09:09 »

USA models have a totally different ECU/ECM. As far as I know, any FI unit that uses a Lambda sensor includes it in determining the fuel mapping. Generally, if any FI sensor is unavailable but the system still allows the engine to run, a fail safe fuel map is used which will be on the rich side. I don't have further knowledge of this particular situation, but that is the standard general protocol.

Hondaman · « **Reply #15 on:** October 29, 2016, 09:34:18 »

Which is what I said, in a roundabout way

Offtheclockuk · « **Reply #16 on:** October 29, 2016, 09:40:43 »

Having ridden to work this morning with the sensor cable tied to the inside of the frame next to the engine (because I'm an impatient idiot) the bike rode beautifully and only popped the FI light on when I whipped the throttle wide open, cleared with a restart of the engine.

A friend of mine will be tigging a bung in for me on Thursday night so hopefully will be back to normal soon and can stop messing haha

Hondaman · « **Reply #17 on:** October 29, 2016, 10:23:03 »

To be fair, you'll probably find the bike rides nicer without the lambda than with it, at the detriment to one or two mpg

Offtheclockuk · « **Reply #18 on:** October 29, 2016, 10:45:31 »

I'm not fussed about the mpg, the extra meat in the fuelling just makes that tiny difference....
Although going from one box to two again probably smooths it out a little too, I'm sure it feels free'er through the revs somehow

All welded and back to twin cans as intended,
Many thanks to everyone who chipped in with suggestions and info!
