I own an '08 Wee from North America. I want to add an O2 sensor. How difficult would this be?
I was hoping it would be as simple as buying a $20. sensor and plugging it into the existing harness. Anyone with a euro bike that needs a North American wiring harness?It would require a Euro ECU and wiring harness.
It's the OCD in me. Also call me a hippie, but I like clean air. It's one of the reasons I started riding in the first place. It also annoys me when I get knocking on low octane fuel at high altitude. I believe that an engine run at stoichiometric will last longer than one run anywhere else.Are you aware it's only an emissions control device and will do nothing for performance?
I thought it was the other way around. Not trying to argue; a quick internet search shows I got it wrong. Now that I think about it the high octane didn't help as much as I assumed; I remember knocking around 9000ft on 91 octane.High altitude means a lower octane requirement.
It is definitely NOT hard pinging; the kind that damages your engine and makes your block ring like a bell. I've heard that before, even from the Wee just before I stalled it on a hill.You may be mistaking the typical clatter the engine makes for pinging. It may be camshaft end float but sounds like tapping two hammerheads together and is louder when cold. It is normal. Pinging sounds like rattling a tin can with some BBs in it that is especially noticeable if the throttle is opened wide at low rpms, like 3000-3500 to start with, and should be addressed.
Since you mentioned it, I have wondered if my bike is Cali emissions or not; the label is vague. I'll get a pic & go from there.The latter will be met by your bike if there a California statement on the frame placard.
I still have not given up on this. There is little difference between the two wiring diagrams; my existing one could probably be modified. The connector could be an issue as the ECU for Europe has two extra pins.The ambient air pressure sensor takes care of the altitude. There is nothing archaic about fuel maps. DL1000 owners play with fuel maps a lot because emissions regulations are met with ultra lean, pushing the envelope mixtures. The DL650 has a later engine design able to meet standards by adding a spark plug to each cylinder and taking settings like idle speed out of the owner's adjustment capability. The fuel map is a part of any electronic fuel injection system. Modern engines are all running leaner than stoichiometric for emissions purposes.
