    I watch this thread with great interest.
    I have a 990 with Leo Vs and it runs well but sucks fuel.

    Just a note to Cyborg about his theories. I had a Trumpy 990 i Tiger and it ran like a wheelbarrow. I fitted a Powercommander and loved it, especially the pumper carb feature. Made the bike powercurve flat and nice and pulled wheelies at will. It did use more fuel though. Interestingly, part of fitting a PCIII to this bike is to bypass the O2 sensor in the header. I did a bit of research and found that Triumph fit the "cheap" lambda sensors that are termed 2 wire. There appear to be dodgy with a stated accuracy of +/- 10%. There are better sensors made by Bosch and others that are 3 wire and heat themselves up and get better accuracy. Maybe KTM use low rent O2 sensors and this inaccuracy / variation could be the cause of the wildly different fuel uses on otherwise identical bikes. Anybody know?

    Meee toooo!

    I have stock exhausts that will be gutted soon, and so does Johnny_5, so all of this is really really interesting.

    :ear

    I have two Sherco dirtbikes....with Magnetti-Marelli EFI on them...would Tuneboy work with those too?

    Thanks Timtiger,

    Tahoeacr will be playing with some Bosch replacements soon and let us know. He has his 990S fully instrumented, a rolling dyno! Now if we could just get the Tuneboy talking!

    Thanks for the info highlandcycles. I have, like many here, tried the "15 minute trick" which enables fast-learn mode. At cold and hot temps. Problem is, my ECU loses what it learns apparently.

    See this 15 minute Idle Trick thread.

    I don't think so.
    These are the bikes supported
    http://www.tuneboy.com.au/Products/Products_Models.html

    It was started for Triumph's, which at the time used Sagem ECU's, since then Triumph moved over to Keihin ECU's.
    So all the bikes supported are either Sagmen or Keihin ECU's, but there are also Aprilia listed which use Walbro ECU's. (I think)

    So, from the bikes listed it would seem it's limited to Keihin, Sagem & Walbro ECU's.

    But these guys seem to do a similar thing for the Magnetti-Marelli EFI bikes.

    Can't say I know anything about it though.

    Well, I'm still down in socal working at the shop. Long Beach GP didn't go well for us as the car hit a wall in practice and is probably a write off. I'll be able to go home Friday night. It's snowing at my house right now but, I should be able to get some time in on the new Lambda sensors this week-end.

    On another note, I talked with our composite guy about doing a carbon fibre skid plate:thumbup and a new airbox top to let more air in.

    Now that I own a 990 I'm really interested in the results of this one....

    I'm starting to get discouraged again, since I sent all the test data files to Wayne on 4/20 and not a word in 10 days. Hopefully he's working on it.

    I hope so too! I'll have my first fuel map done this week-end to try. If it turns out good I'll e-mail it to you. That way if you do get it working you can load a map real quick. The timing control is what I think will be the key to mpg if Tuneboy will ever come on line.

    Wayne emailed and said he was sorry for the delay and also said all my data files from the test programs looked normal, so he very much suspects the cable at this point. He asked that I mail it back to him and I did. So, expect a delay while cables fly back and forth across the Pacific...

    I mailed the old USB cable back to Wayne a few weeks ago and finally got the new USB cable back a few days ago. I borrowed the same laptop I had last time and plugged it in and PRESTO! IT WORKED! :clap
    It was a bad USB cable all along (groan).

    Popped up my ECU info as soon as I fired up TuneEdit.

    ECU Serial number = (sorry that's private :wink:) , ECU Type = 610.41.031.100, Tune = KM601US0704501


    Now we're cookin'. I just sent the SN info back to Tuneboy for the unlock code and look forward to seeing if I can get a peek at my ECU's existing map!

    Stay tuned err... well you know :lol3

    I was under the impression that the Aprilia's that Wayne originally covered were also using Sagem units. But I don't know about the SXV and RXV.

    EDIT: shoulda looked at the actual tunes list. Looks like Benelli and the later Aprilia's have common 'brains'. Not sure if that's a good thing :D

    Cyborg,
    I updated Wayne and sent him my e-mail from 11-20. I also forwarded it to you. I'll try and figure out how to copy my map and e-mail it to you to try.

    Thanks Jeff. Hopefully Wayne and Emma can sort out the code issue soon.
