Semi Active Ohlins suspension

  1. Same result for me, There is a lot of info about this subject on the Ducati.ms site.

  2. Does anyone have any ideas of how good this is 2up? Just wondering if this is worth saving the extra £££'s or is skyhook still the better option for 2up touring mixed with aggressive solo riding/track days?
     
  3. Setting the damping to 1 activates the system in that particular rider mode/setup etc. you have potentially 16 suspension options... 4 riding modes and then 4 combinations of rider and/or pillion and load.
    You can choose to have the stock system defaults or your own fixed parameters or by setting the damping rates to 1 then the ohlins kit takes over and goes semi active.
    maybe you like semi active in one up sport but prefer the fixed defaults for two up touring

  4. The Skyhook system is not active when you select Sport Mode and just solo rider, then it acts just like normal suspension so you can feel what the bike is doing. Add luggage or pillion on the settings and skyhook comes back into operation, as it does in all Touring and Urban modes, not played with Enduro yet:)
     
  5. My uses are mainly in sport mode and occasionally use touring. I have changed all the mode setups to 1 for now. However I did write them all down, albeit with the updated ECU installed. So atleast I have an idea what to set them back to when needed.

    [TD="class: alt1"]Jut spoke with Matt Sage from Ohlin's USA. Kindly gave me 20 min. of his time. I asked him to explain to me how this thing works and he said it uses the motorcycle's potentiometers and senses the acceleration, deceleration, wheel speed, throttle position, wheel spin if any, HP setting and a lot of other things he said he can not talk about. Also he told me the algorithms for c & r are also tied into the pre-load settings, not changing your pre-load, but changing the c & r values based on what the pre-load setting is, e.g. load changes, unless your maxed out across the board
    He also went on to say that unlike Sky Hook that changes suspension parameters in a millisecond, Ohlin's SCU makes changes in their suspension in anticipation of what going on with all the data coming back to the SCU to prepare the suspension. And the SCU is constantly changing the c& r values.
    He also went on to say that your sag setting is veryimportant because if you are overwhelming the spring you really won't get the true affect of the SCU. I weigh 180 and said the stocker was borderline fine for me but for 2 up riding or bags on I should change to the 100nm spring.
    All from the horse's mouth.
    He also said the stepper motors were designed in anticipation for this operation.

    The Ohlins stepper motors were designed initially with this SCU in mind , a guy on a different forum contacted Ohlins directly which stated this

  7. I haven't bought an SCU (yet) but have just got up rated springs front and rear and it makes a big improvement having the correct springs. Ties in with what the Ohlins man says about not over whelming the springs irrespective of having the SCU or not
     
  8. Thanks for the info so far guys, anyone has anymore let us know.
     
  9. I can feel an expense coming on....shit...new springs and new ECU bloody hell whats that gona cost me???
     
  10. I'm not a track day aficionado or off road wunderkind but have had my 2010 S Touring for 3 years now, been to Corsica, Picos and Croatia on it and have just fitted the new Ohlins SCU to it. In my humble opinion, the bike now feels more 'planted' on the road. No twitches or jitters when riding on uneven surfaces and therefore installs a lot more confidence. The bike has been transformed and I guess what Ohlins originally intended the bike to have fitted in the first place.
     

  11. I agree it does that, feel more planted. However I've only ridden with the upgraded ECU for about 40 miles and haven't had a proper run out yet. I intend to take it to Scotland soon to see what the differences are and how it's changed across a broad range of riding attitudes.

    Sure it's more planted and feels sure footed in corners, giving more confidence without it running wide or diving too much. So hopefully it's the change I've been looking for. Have toid with the idea of changing the rear spring, but i don't have a pillion and I'm about 105 kilo's. so need to check if changing the spring will bring a big enough difference to warrant spending about £180.
     
  12. SCU Installation - disconnect battery?

    Installation guide / instructions, point (3) disconnect the negative battery terminal


    So, is there a permanent live feed to the SCU i.e. it has a 12v+ supply even with the ignition off?...or is this just the usual precautionary advice you get when working with any electrical items?


    The reason I ask is it would be nice to fit the new SCU without disconnecting the battery and so having to reset from factory defaults (clock, DTC, km vs miles, degreesF vs degreesC, etc and any other custom settings e.g. ABS etc) on reconnecting.


    Thanks

  13. Andy,

    I did do this at 1st because I didn't want to reset everything again!

    I do think its precautionary advise like you say, however, it could be because the control unit has to learn the travel parameters of the suspension as it goes through this on the initial power up...?

    Anyway... To be sure I then disconnected the battery and installed a second time, resetting clock, dtc, mph etc...
     
  14. From looking at the wiring diagram the OEM suspension computer is only powered when the ignition is on, since it uses the same connector the Öhlins must be likewise.
     
  15. oooh andy w is fitting one...

    come on andy, your review could be the thing that may tip me over the edge...

  16. The new SCU needs to run through the calibration process and the instruction to do so comes from the bike controller following a power-off reset. The resetting of the bike instruments and DTC settings only takes three minutes. You will spend much longer changing all of the suspension settings, 4 figures for each of the 16 riding modes and you have to do every one. Don't fret though, it's worth it.

    I fitted mine last week. I have the 100N/mm (heavy) spring fitted as I do a lot of two-up with luggage and my bike has covered just over 32,000 miles so far.

    The new SCU makes every mode even more supple and comfortable than before and greatly reduces dive under braking in Urban but in Sport it comes into it's own. The front end soaks up ripples and bumps better than urban used to yet with precision and with awesome grip. Two-up response feels just as good. I have tried the Skyhook since fitting my active SCU and by comparison the Skyhook bike feels rather crude and choppy.

    I love my bike and it just got even better. £260 for this much tech and this much quality? It's a bargain. 20130725_194736.jpg

  17. This is really throwing me off now. Exorbitant skyhook priced model or just per skyhook with this... Ahhh my brain can't take it!?!
     
  18. Then tis yer bum which should make the decision (by which I mean "seat of the pants" ", before someone chimes in!)
     
  19. Morning chaps.

    I'm about to fit one of these, but I have the OE alarm installed. Anyone any idea whether that will be affected by removing NEG from battery?

    Thanks

  20. No you will be fine

    I have the Ducati alarm and it didn't effect mine
