Hello out there.
Just thought I would do a post on fitting the new o2 sensor.
Bike is 2003 xx3 uk bike 32,500 miles.
2 delkavic 450 cans with baffles removed..
I originally disconnected my o2 because of back fires and surging, but a lot of that down to the previous owners and there crap servicing.
I fitted a o2 eliminater a year ago and was keeping an eye out on my mpg.
The bike was smooth, ran great but I was getting 31-35 uk mpg, usually 33 mpg.
With the cost of fuel going up, I decided to pay the £350 GBP for a new o2 lambda sensor, and see what happens.
I have just changed the oil, fitted new vacuum lines and the o2 sensor.
Test ride was today, I didn't change my riding style, did back roads bit of motorway and stop and go traffic, came back home and did my new mpg calculation.
Now I'm getting 48.6 uk mpg.
I know a few guys were saying you need to power commander it with the o2 delete, but I though I was ok, after all I did disconnect it after 30 mile trip when i bought it, so i didn't know any better, apart from the suspicious 31-35 uk mpg.
So you guy's were right, I was wrong.
My advice would be like every one was telling me, if you disconnect your o2 sensor get it power commanderd, your mpg will be crap.
Or like I did in the end, bite the bullet and spend the £350 on a new o2 sensor, its a few £ more than the initial power commander, but you dont need it dynoed.
