    Re: VDSTS Info - Instructions

    I was reading up on your TPS position being 3.7º whereas on the Stelvio has the same MM 5AM ECU having 4.7.
    On the VDST software this TPS value is the potentiometer reading. (Floating value)
    When TPS reset is done it tell the ECU your idle (Start) position and follows the mapping from that reference point.

    Having done a few tests with the VDST I was wondering what would be your “Stepper Motor” value?
    This value is usually taken when engine is hot.

    The VDST can monitor this value by selecting …… on the graph page Option / Mode and turning on Stepper (Close loop), (Initial), and (Delta)
    Initial value is usually 100.
    The Stelvio ECU has a fix idle 1150rpm set point.
    This 1150rpm value is attained by opening /closing the stepper motor valve. (From approx. a 20 to 150 value).

    Balancing this stepper motor value, at idle, is done with the manometer U-tube and bypass screws on the TB’s.

    Re: VDSTS Info - Instructions

    The Bellagio service Manual is somewhat confusing:
    It would appear that 3.7 is ok see below.

    In the throttle body sync section it states:

    Turn the key back to "ON" and restore
    the Axone session.
    · Check that the "Throttle" value reading
    is 4.7 +/- 0.2°. If the value is incorrect,
    replace the control unit and repeat the
    procedure from the start.
    · Completely close the two by-pass
    screws on the throttle bodies.
    · Start the engine.

    Then in the CO2 section it states:

    On the left throttle body, using the
    throttle adjustment dowel (3), adjust
    the throttle potentiometer to 3.6° (+/-
    0.1°) visible on AXONE.
    This value corresponds to a reading of 536 mV (+/-
    20 mV)

    I was thinking that if you could not adjust the TPS what is the point of buying a VDST.

    The thing that worries me is that the workshop maual is correct but seems to contradict itself?

    Re: VDSTS Info - Instructions

    The VDST will accurately give you the TPS value in º's and gives you all sort of information.
    Temperature, pressure, fuel trim ......its a matter of interpreting the values.


    When adjusting the Stelvio's TB on idle I keep an eye on the rpm value, TPS value, stepper motor values and a U-tube while adjusting the by-pass screws.
    At +/- 3000rpm ..... I check rpm, U-tube ..... and adjust the TB connecting rod set screw.
    I for one would'nt be able to work without the VDST.

    Re: VDSTS Info - Instructions

    :eek: Conflicting info in the Bellagio manual??? Doesn't surprise me. :whistle: The Italians backed both sides during the war. Manual also specifies 15RC instead of 5AM, tubeless instead of tubed etc.

    3.6 sounds like a nice number to work with, much closer to reality and bike really is running well. Will play with the screws and VDSTS next weekend and see what I end up with.

    Just sad they dropped the Bellagio...I blame the Americans for that! Bloody design rules! :(

    Re: VDSTS Info - Instructions

    Hey John

    Did you ever get an answer from MGNA on the correct procedure to set up the Cal Vin? Using Centurion, I'm able to reset my TPS as per the instructions (i.e. I get a "PASS" result), but the AlPalin_0 remains at 2.3 whereas I believe the correct figure is meant to be 3.1. The value does not change when I twist the throttle, whereas the TPS reading varies from 3.7 - 84.4. I don't understand what this AlPalin_0 is representing.

    Re: VDSTS Info - Instructions

    Just recently got the Centurian S and set it up on my laptop. Carlos and Sandros from Technoreasearch tech support were not only helpfull, but genuinely interested in getting it right. If you have any issues, just call them. I reset the TPS on my new Norge, and found a noticable performance improvement.

    Cheers

    Re: VDSTS Info - Instructions

    I'm a little confused with exactly how to reset the TPS on my 2001 V11 Sport with the 15M ECU.
    Anybody have good instructions on how to do it? As far as disconnecting the sync bar that goes between the 2 TB's, how does is that removed? Mine seems to be on very tightly, and it seems as if I force it, something may break. That ball joint seems kind of fragile.

    Re: VDSTS Info - Instructions

    Pretty much the same procedure as the Cali on page 4 of this thread. You loosen the screws on the TPS and move it to get the desired reading. As for the sync bar, I haven't looked at a sport in some time. It only needs to be disconnected if you are going for the initial 150 mV reading at fully closed throttle plate.

    Re: VDSTS Info - Instructions

    Thanks John!
    Is there a trick or method of removing the sync bar/connecting rod? I gave it a tug the other day, and it seems to be on there tight. I'd hate to break it trying to remove it.

    Re: VDSTS Info - Instructions

    I haven't laid eyes on one for some time. I wouldn't want to speculate. Hopefully someone who has removed one recently will chime in.

    Re: VDSTS Info - Instructions

    It finally cooled down enough to where I could adjust TPS and balance TB's (we've had 90-100f the past few weeks). Thanks for all of the help and info with the VDSTS everybody. However, more questions:
    What does the fuel trim do exactly? Does it affect fueling throughout the entire rev range, or just at idle? I've read to make sure it's set at 0, but was wondering what would happen if I started adding or subtracting from it. I'm assuming that adding (+) would add more fuel.

    Re: VDSTS Info - Instructions

    The 15m is an open loop system. Adjusting the trim will impact the fueling through an RPM range, but there is no definitive information on how high the RPM will be impacted. Most of the bikes I've set up seem to do better with a negative trim, but each bike has a value that works best for that machine.

    Re: VDSTS Info - Instructions

    I have a MM 5AM on my Stelvio. I assume the 15M works the same
    Hooking up the VDST and changing the fuel trim ....... changes the entire range. (Adding does add more fuel)
    https://www.guzzitech.com/forum/160/1676.html?start=50#p37272

    Milage was not so good back then .....The bike was breaking-in. I had it set to -60 and getting +/- 200km
    Now at 15,000km I have it set for +20 on my bike and getting +/- 200km before the reserve light comes on.

    Did anyone happen to grab the latest and greatest VDSTS PRO software off of the TechnoReasearch site before the stopped supporting it? All I have to install is the very old version on the CD when I first go the package.

    VDST standard users can use the Centurion-S software. VDST Pro users is not compatible, so I will host the file here in the very first post of this thread soon.

    If you've purchased the Centurion-S in the last year or so, they now have a software user interface update(r) tool. See the first post of the thread, or click >HERE< to download and click >HERE< for the PDF how to. TechnoResearch is available CST 9-5 M-F for support and free online demos.
    The closeout version of Centurion-S is about sold out (only a small handful left). The new version including bluetooth for smart devices is soon coming, and should retail for around $349 or so.

    Contact me direct with any questions, or purchase info >HERE< on the online Store tab above under Electronics.

    So I'm down to the very last five kits at the sale price; https://www.guzzitech.com/store/product/tr-centurion-diagnostics/ -- I have exactly one 15M/RC kit ('99-current 1100's and B/N/V7), one 7SM (Cal 1400) and three 5AM (ALL CARC model) kits.

    Once gone, they are gone for good until the release of the new Bluetooth version, which will likely be ~$349.95 for a single ECU Kit.

    Has anyone ever tried to install the Centurion software on XP running as a VM under under Linux?
    Sounds silly, I agree, but the old Laptop I am planning to use has Lunix on it which my son needs so I cant simply push it off and install XP.
    In theory it should work under a VM but devil is in detail.
