lambda/o2 sensor question?

[svsam]

I have my self a 2010 svs as some may know. not long after buying it i bought a yoshi can for it with downpipes included for a bargain price.
Being a 10 plate bike it has a lambda/o2 sensor that goes into the exhaust just behind the foot peg, and as these down pipes must have been off an earlier model it doesnt have the hole for it to fit into the exhaust :s
I have ran it for over a year with no problem at all, and the exhaust seems great (Y)

I just want to know, is not having this sensor in the system going to damage the bike or effect the long term running effects in any way?
You may ask why i wander now, i guess im just getting older and thinking more sensibly.......or maybe im just worried about loosing power :D
Cheers Sam.

No issue at all.

The O2 sensor mesures ,now hears a shock, the oxygen in the exhust gasses.
It allows the engine managment to keep the air /fule ratio spot on for emmisions.

If the SV ecu is like most. the O2 sensor is only used for idling and cruising to keep the green people happy.

So in a nutshell. But having no o2 sensor will make the bike pollute more but should not affect the WOT power of the bike.

Depends if it open loop idle but in general the O 2 adjust idle as well as normal running.

Oh right, so all should be okay, good good.
Might try get a fixing welded in over the next couple of weeks.
Got a set of curvy cams on the way, along with induction kit, so may as well have it put in whilst im doing work.
The next question is simple remap or power commander???

[SV650Racer]

The amount of correction is very small and for emmisions only. The SV doesnt run a closed loop system so cant adjust fueling anywhere near as much as people think.

[NTECUK]

The power commander has the advantage of being updated via the support site.
So as you mod it your likely find something that will.fit.

[svsam]

you think, from what i see there maps only go as far as exhaust and performance filter, since im doing cams and induction kit will it not have to have a custom map? the same as ecu remap?

[SV650Racer]

Ideally even if your doing just a slip on a custom map will be alot better than any downloaded map.

The downloaded maps dont take into consideration that every bike has a different fueling requirement due to varying tolerances in injector flow rate etc. The flow rates can differ by a large amount, hence why if you had the budget matching injectors would be one of the best and most simple ways of gaining BHP.

Ive had 2 indentical bikes on the dyno similar mileage and the maps for each bike were in no way identical.

Im yet to see a bike come in with a downloaded map that was right for that bike.

[NTECUK]

So best thing is bolt it all on and take it to the dyno.
Remap on aFord focus 20o0cc TDci car is £400 2 dyno runs.
Not sure for a bike.

[SV650Racer]

Generally a full custom map is around the £150-£180 mark but does vary from area to area alot. If done correctly should take around 3 hours. That are some places out there I know for a fact that just download a map and tweek it slightly with hardly any dyno runs..so ensure wherever you go they know what they are doing and do it properly.
