Power Commander on a Euro DL1000?

I have a Euro 2007 DL1000. It has an O2 sensor and cats. Power Commander recommends disabling the sensor if I install a PCIII.

I'm thinking the cats won't like that and will plug up. The whole idea of the O2 sensor is to keep the cats happy eh.

I thought all newer VStroms came with cats, but a PC would ruin them quickly. Is this a problem or not?

No way I'm going to disable my O2 sensor and I'm not changing the mufflers nor removing the cats. So I guess the PC is not for me, pity.

I notice that the PC people actually make a PC for Harley that comes with an O2 sensor. I can only hope they make a unit for the VStrom that uses the onboard O2 sensor.

But, in order to keep the cats happy, the mixture must remain quite lean I think. So richening the mix might not be possible, or the O2 sensor might compensate and nullify the PC richening. Nobody knows.

Any comments from anyone with an O2 sensor and cats? Do Cali bikes have them?

Thumbs up Power Commander on a Euro DL1000?

Hi Jim, Yes the California bikes have them, and the PC version for them does not do much,

Power Commander says that removing the ecu pin for the O2 sensor or wiring around the pin is the way to work it with the sensors,

Without the work around, the O2 sensors basically reset the ecu back to stock and defeat the purposes of the PC.

The O2 sensor is not an issue on 49 State or Canadian Bikes for that matter,

Sorry,

Enjoy the ride, and best regards,
Blair

I have an 07 DL1000 California Model and can find no evidence of an O2 sensor anywhere. Im also running a PCIII (not the Ca version) and noticed a huge improvement over stock. If there is an O2 sensor on the california models...can you tell me where it is located.

That information came from Power Commander. When there is a bung for an O2 sensor, it is usually located on the exhaust pipe,

Good news that the California model is a true plug and play upgrade with the Power Commander,

Thanks...I ran the entire length of both exhaust pipes and there is no O2 sensor anywhere. I'd be surprised if the muffler contained a catalytic converter...but I could be wrong. Either way, I installed the 49 state PC awhile ago....and it totally changed the way the bike performs

North American bikes do not have O2 sensors. They all have cats.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

So if you have Cats, doesn't the enriching of the PC make the Cats foul up? Guess that's not a problem for those who put on aftermarket cans... yes the stock pipes are heavy and the Cats are the reason.

I kind of like the fact though that my bike doesn't put out a lot of pollution.

My O2 sensor is on the right exhaust pipe, easy to see behind and rearward of the footrest.

Too bad that my VStrom exhibits the same bad behavior that those without O2 sensors have, below 3 grand it just doesn't' like cruising smoothly.

But you know, if I cruise at 3 grand it's smooth as hell so that's what I'm going to do.

To compensate I think I'm going to get lower gearing from Blair, 16/43 sprockets and a new chain. That should help me keep over 3 grand and climbing those mountains will get easier too! Ever try climbing slippery, rough, and steep switchbacks and keeping it above 3 grand? It's a fine ballet dance on the throttle my friends, especially with stock gearing.

Wheelies will be easier too!

The Power Commander only richens a little in specific places on the map. Cars in the 1970s burned richer mixtures than we have now without being cat killers. Going to a 43 tooth rear sprocket and keeping it above 3000rpm should work fine though.

I don't think 70s cars had Cats but I know early Cat equipped cars had to change them quite often.

Well Blair is sending me 16 front sprocket, 43 rear sprocket. a new chain, and a chain riveter tool! Blair is a great guy to deal with, thank you Blair!

I may be able to use my old chain on another of my bikes. My VFR chain is getting a bit old. Hopefully it'll fit because my original only has 5500 miles on it.

My new Tourances should arrive any day now too, renewing my 2 year old baby.

The 1978 Honda I had was one of the few cars that could pass emissions without a cat. Almost all cars had them that year.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
