    Using a wideband O2 sensor

    in Technical Topics

    Posted

    Here's a report from a former member who did it himself and later went to a dyno. He used a MyECU instead of a PCIII but that doesn't change much. Most dynos around here are the interia type like he used.

     

     

    Yes, I remember reading that. I had been following these threads and waiting for a distilled thought process on the subject. I think probably a few runs on the dyno won't hurt if I can find a good operator, and I will probably invest in a wide-band set-up for the fine tuning and tinker factor. I know that, at the moment, the mapping is far from good on the V11 since the switch to pods and FBF cans down here in San Diego. I'm just not ready to pay for a blind fix without some better knowledge on the product I'm paying for. Particularly since I could care less about peak power-I'm more interested in a clean powerband.

    It is that simple. But only you knows what is better. Doing it myself is better to me, but I like the endless tweaking. Many don't. If you want to immediately get a good map, a dyno run does that for you in an hour or two.

     

    What a dyno center will do, is go for that air-fuel ratio. So they do the same thing, except they have a rolling road and hopefully years of experience. And automated map changes. The major difference is how long it takes.

     

    I am also assuming, due to the difference in pricing, that a narrow band sensor will not- is this more or less correct? I've done all the work on my bikes, but am still trying to get smart w/ the mapping. Would rather not pay for dyno tuning if I don't have to. Thanks, raz.

    So I've been following the discussions on all the fuel managment options, and have a question on the use of a wideband sensor in general: Is a wideband O2 sensor, in conjunction with an AFR gauge, a worthwhile investment for tweaking a power commander map, or is it better to just pay for dyno tuning? In other words, is it as simple as going for a decent air-fuel ratio throughout the range or am I oversimplifying it? :luigi:

    V11 suspension setup

    in 24/7 V11

    Posted

    Many thanks for the info.it's been a great help.I certainly understand far more now than I did before.I'll just have to put into practice now.

    I haven't had my forks set up by anyone yet as I bought a set of Ohlins from a dealer and am still deciding which bike to fit them to.I was intending to put them on the LeMan as thats the one I'm messing about with the engine tuning on, but then got to thinking that I'm sure if correctly set up the Marzo. forks would be equally as good as the ohlins. I came to this conclusion by ogling the new MV Agusta's at my local dealer when I noticed them all fitted with Marzo's.

    I can then put the ohlins on the Rosso Mandello- I thought the gold colour would best suit the R.M's paint scheme{as well as adding to the handling of course}

    Anyone got any thoughts vis Marzo against Ohlin?

     

    Andy.

     

    My thought is just that I'm envious you have to decide which V11 to fit your Ohlins suspension to. :notworthy:

    Otherwise, the Marz forks seem fine to me once set up properly, and I hear the Ohlins are a little harder on fork seals. I'm sure others will chime in on this.

    Rode a V7 Cafe Classic today...

    I stopped by GP Cycles today in San Diego to check out their current offerings, and ended up taking a V7 out for a short test ride. What a cool little bike! The fueling was spot-on, power was adequate (despite the low horsepower ratings) and delivered nicely across the RPM range, and the handling was nice and stable. The riding position is as comfortable as a standard bike should be, and much less rackish than the Ducati's Sport Classic series, despite the low bars. Suspension seemed a little soft on spring rate, but the damping wasn't too far off and the chassis didn't seem to mind the rougher sections of road I traveled over. Combined with a relative low weight carried nice and low in the frame, the handling was good, if not a little slow from all the rake in the front end. Aftermarket pipes with a little more bark would be nice, but the engine wasn't overly quiet and you could certainly hear enough of that v-twin sound over the road and wind noise. Fit and finish was much higher than I expected as well, and was far from cheap looking. The mirrors even stayed where I put them while providing a clear, vibe-free picture behind me. Overall, I really liked the thing right off the bat, and am seriously considering selling the Cali Aluminum and my DR650 dually to make room for one in the garage. Any takers? :mg:

    What are you talking about untested motor,Rotax has some of the best four stroke motors on the planet Bar none and do lots of development work for other manufacturers around the globe.

     

    Who do you think did all the development work on all BMWs motors for there 650 duel sports and there new 800s,not to mention how many lite aircraft have Rotax motors in them and on and on,Rotax is actually owned by Bombardier here in Canada,excuse me for getting my nikkers in a knot,my 2 cents.

     

    I feel better now Stu.

    Well, that wasn't a cut on Rotax or Buell at all. It was a new motor, even though the best may have been involved in it's development. Notice I said "somewhat". When the first 1125's came out the fuel mapping wasn't sorted, it used a lot of fuel and the bike was too new have any reliability background. And then the jackasses at Harley pulled the plug on Buell. So my thought is just that I was happy with the track record and performance of the air-cooled bikes and leaned that direction as a result. In the end, I cancelled the order for the XB12 and got engaged instead, so I may never get a chance to form a first hand opinion of either one. (More evedence of flawed judgment, I know) :mg:

    I hope MG gets it together

    You know, I bought my Cali Aluminum under the thought process that I needed a cruiser type bike. And after adding a fly screen and a good set of rear shocks, it's pretty damn good. But I really think the cruiser/comfort thing is overrated. My Tenni is just as comfortable on the road without tiring my back, and the wind blast gets tiring on the Cali after awhile. So now the Cali gets used for two-up riding and grocery/hardware store runs 'cause of the extra storage.

    Sorry guys...the first ride (all three and a half minute's worth) :lol: is confidential. The second ride will be fair game for forum review. Thinking Eastern Sierra range, up through Bishop, CA and into Reno. Then maybe west through Gold Country and up around northern California. Bars and campgrounds will most likely decide the rest...

    Finally headed home after having been away from my Tenni (okay, and my girlfriend, too) for the last eight months. In less than 3 weeks, I will finally get back on the road again. Needless to say, I'm a bit anxious to get back to my baby. And my girlfriend (should she read this). :mg:

    Sprung for the Motogadget Speedo...

    in Technical Topics

    Posted

    Well, after 3 years of an intermittant tach and faded needles, I went and blew a whole lot of cash on one of these motogadget speedos. Anyone used one? It looks to be pretty top-shelf. Of course, compared to stock, how bad could it be? <_>

    Open for suggestions on mounting the oil-temp probe...my thought was in the sump somewhere. I'm damn near halfway around the world away from my V11 at the moment, still working in Bahrain, and won't get to it for another couple of months so it's mostly retail therapy at this point :D

    V11 Land speed record?

    I saw 131 on my GPS, but it was a long, flat road in the middle of the Nevada desert, and took a while. The fuel cut-off kicks in right there (or did for me) so I'm not sure how much more you vould get out of it.

    There are obviously some good deals happening on these bikes, and you can expect some smoking deals on used Buells. I feel sorry for those out there with Buells right now, only because while I'm sure they are happy with their bikes, they are now virtually worthless monetary wise.

    I personally am not interested in any Buell, especially the 1125, which I feel could have easily been a much nicer looking bike, and feel that it's overall physical appearance has been a major contributor to it's less than agressive sales figures, in spite of winning a U.S. race series custom made to it's specifications.

    True enough, but the resale on a Guzzi has always been pretty dismal as well. So, now I have to decide between the air-cooled XB12 and the new 1125. As much as I like the idea of all that power, I do like the familiarity of the air-cooled mill over the new, somewhat untested rotax motor. The looks of either don't bother me much after seeing them in person.
