Anyone know where I can get the gizmo that overrides the CO2 sensor

Have a look on Dyna Tune's website(not sure maybe).

Why do you want to over ride it?

Got some V&H cruizer comming. No CO2 fitting. I was going to override it and then fit a FI Tuner Pro. Or do I just need the FI Tuner?

You will need the override or else the FI light will stay on.

The part I think you need is an Oxygen sensor eliminater which you can get on www.dynojet.uk,

The Fuel processor will actually be the bit that eliminates the need for the Oxygen sensor but the warning light will show. Putting the O2 Sensor eliminators in will just turn the warning light off, no more & no less.
Forget the O2 sensor eliminators, all that does is loop the 2 wires around to each other to create a circuit
just cut wire #23 on the ECU!

Oh I forgot to say if you do go the route recemended by Pledge, which to be fair most people do! Don't forget you need 2x CO2 sensor eliminators.

Dynojet UK say they do not do eliminators for a M800. They say that it is a disable and the instructions on how to disable are in with the power commander that they supply which is a lot more expensive that a FI Tuner Pro

Yeah that's the one, I just double checked on Healtech's site, I have fitted one to a C800 on a 2010 plate so you may find this link useful. although it's possible there may be differences but I don't think there are apart from the color of some wires

Hi Stone I have the 2007 m50 and have V&H Cruisers fitted,you do not need a CO2 sensor override,these are not fitted to the pipes.I have got the Cobra Fi2000 Fuel Processor fitted also a K&N filter,try out the pipes first before you buy the processor unless you are going to improve the air quality/rate,(with a new K&N filter).A lot of people say do the 3 at once,but not everyone can afford to do this,or want to do this,just changing the pipes should not necitate a fuel processor but this a very emotive topic,this is only my opinion.I done mine in stages.Good luck on whatever you decide to do.nb: just to add both Mr Intuder and myself have quieted down the Cruisers,another reason to hold back until you are sure.

Lovely looking exhaust & a great price but by Fek without quiet baffles added doesn't it create a rumble

Well spotted Alfie, I gave no thought to the fact that the CO2 sensor did not come in until 2008, I simply answered the question & gave no thought to the reasoning. I think this raises the issue of giving a little more consideration to why a question is being asked by any new member, due to the fact that there are subtle differences between the bikes and years. for a newbie there must at times seem to be an overload of info and where and when it is applicable

Job done!! Sent back FI Tuner and K&Ns. Got a boss welded to V&Hs and fitted CO2 sensor. Much cheaper. Bike runs good, sounds good. Dec killers fitted. Need to stop spending now!!

PostSubject: Re: CO2 sensor override   Sat Nov 12, 2011 9:38 pm

Hi Folks,

I'm confused about this fitted or not fitted C02 sensor debate?

My M800 is the same as Alfies M50. Mines a 2007 57 plate but it's a K6 (2006 model year) it has a C02 sensor hole on the pipe from the rear cylinder but not on the front pipe. A mate of mine has a 54 plate C800 that's carbs not FI and obviousley his has no sensor holes. I saw a 2010 C800 and a 2010 M800 last week and I think they had the C02 sensor holes on both pipes?

So it would appear you have to have a look at your own bike before deciding if you'll need bosses welding to after market pipes etc etc

PS.... I found that a 2007 Bandit 650 C02 sensor would replace the one that had been crossthreaded by the chimp that owned the bike before me. I might write up my findings re C02 sensors in a seperate thread? The short version is there are only 2-3 different types. So £12.50 for an as new Bandit one was slightly more appealing than £190 plus vat for a new one for an M800 Laughing

PostSubject: Re: CO2 sensor override   Sat Nov 12, 2011 10:12 pm

Ok Mate,

Well it would appear that aslong as the one your replacing has the same number of wires and is colour coded in the same way. It doesn't matter a toss how long the wires are. The only difference with the Bandit 650 item is the wires are approx 1/3rd longer because the route it takes from the downpipes to the ECU is approx 5" longer.

Where the sensor fits on the standard pipes V's where it fits on my HH Short cuts meant the wire on the original (crossthreaded) sensor had to be wrapped once around the bracket for the right hand side panel to take up the slack and with the Bandit replacement it had to be wrapped around just under twice. The C02 sensors on the Suzuki Van Van & the GZ125 are identical in every way to mine but I couldn't find either of those for sale? From what I can gather a C02 sensor is a bit like a tyre i.e. not made for a specific model or make. So aslong as it'll screw in at one end and has the correct connection at the other it'll probably work?

Don't take that as gospel but it isn't guess work either Laughing and if you can pick one up for what I paid your not investing a lot of cash to find out if it'll do the job.

Thanks lads but don't forget I'm talking about a brand new one in a nice plastic bag from a Suzuki dealer V's a used one from a wrecked 1200 mile old Bandit 650 via an online breaker!

Personaly I reckon the breaker option was the way to go but just thought I should point out that it wasn't brand new.

New or second hand, who cares. Its the fact that your research has found that alternatives are ok with the bike that matters, it opens up the search possabilities when someone is desperate

Hi all you wiring wizards   The new (second hand) V&H Straight shots came today and there's only one CO2 boss fitted to them, I'm guessing if I just cut this here "wire 23" thingy on the ECU? I'll be able to do away with the sensors and just plug the holes with a bolt on both sets of exhausts, and swap and change to my liking.

ps. it won't make my bike run crap or anything will it?
pps. is this wire 23 numbered or anything?

Cheers.

If I recall there was a while when some of the M's only had one sensor so I would presume the pipes you bought have come of one of them originally, will be interesting to see how you like those after the pipes you are running now. I think they will be louder but not anywhere near as deep

Hi you lot, I have come across a set of highway hawk pipes with baffles, my bike is a 2011 with only one 02 sensor and apart from my home made TRE my bike is standard with a standard air box and filter. If I cut wire 23 to do away with the 02 sensor will my bike run OK and not run lean? I have read all the stuff on the subject and am still not sure which way to go! I could make a boss and fit the sensor but if I don't need to then all the better, I believe its 12 x 1.25 thread if I need to make one and its not really a problem to do so but am interested to get any info from you lot as you can't beat experience. cheers chaps!

Are you sure it's only got "One" o2 sensor Mick? (which one have you found) You'll also need to check if it's got a "Wire 23" on the ECU? Not sure when Suzuki stopped putting them in after 2010?.

Your bike should have 2 CO2 sensors, can you check for us that your bike does have a wire going into port #23 because we are unsure of the year when the wiring changed happen. If you have a wire 23 on your year still then yes cutting it will be fine.

Thanks for the reply, only one sensor in the top exhaust that I can see, is the bottom one hidden somewhere as its not visible. I read that mine should have two so am a little confused! The ecu is under the right hand side panel as I understand so will drag the big heavy thing out of its lair and have a butchers at the ecu plug when I get chance, can't wait to get em on and annoy the locals!

Thanks Dave, just had a peep at my plug and the wiring is different, its got two black and white wires so am going to boss the pipes up and keep the 02 sensors as I think the cowards way out is the right way out for me, scared of cocking the ecu up or blowing some electronic gadget that Mr Suzuki will make me remortgage my house to replace.

Sounds like the right way Mick as we were unsure from 2010 but now we know. leave alone for now, until we get an official Suzuki wiring diagram we are at a loss but you have really helped us by confirming the changes happened in 2011.
