    I got an iice unused unit from one of your customers

    Now my temperamental r1100rt is much smoother.

    Since I do the same commute every day I have a pretty good "test track" that I know very well and how the bike feels and responds.

    The "raspiness" under acceleration is gone on the low end.

    The hesitation between 3k and 5k rpm is gone.

    Between 5k and 7k it feels like a bit healthier.
    The bike always felt too lean. Now it feels about as good as it could be.

    The people that say it does nothing perhaps they have not a well calibrated seat of pants.



    It does what it says it does.

    Waiting for more products to come.

    As I understand it, some of the later (cleverer?:D) bikes 'learn out' the temperature spoofer, hence the need for a recalibration part.

    3D,

    That is also my understanding that the oxygen sensors recorded the increase fuel to air ratio provided by the IICE Air and recalibrate the bikes computers to bring down the fuel ratio to the BMW prescribed ratio...hence we lose the use of the effectiveness of the device at all but the -30 setting...at least that is my understanding. Why the bike does not also "tune out" the -30 setting fuel ratio is a mystery to me.

    Can someone verify what exactly is happening that requires the recalibration which PS is working on?

    I always can appreciate the "why" as much as the "what".

    Thanks...Phil

    As I understand it...

    The IIceAir is just 3 different thermistors in a single housing. Each thermistor has a different range (a thermistor is a resistor that changes valve based on temperature) which you can select using the jumper. For "zero" offset the jumper connects to the stock sensor.

    The issue is that BMW used two different value thermistors depending on the bike / ecu. The Air was developed based on the value of one thermistor. It has been discovered that the offset values between the two OEM thermistors is such that the -20 setting of the Air closely matches the resistance values of the stock thermistor used on the R1200, F650 and a number of other models. (Poolside posted a chart in this thread.) Basically, there is no offset on the -20 or "zero" setting if you have one of these models and the -10 offsets will be +10 actual and the -30 will be -10 actual.

    From what Poolside posted, the fix appears to be a resistor on a jumper board that will plug onto the selector pins of the Air. The resistor should adjust the values of the thermistors in the Air to more closely match with the values the ecu on the affected bikes expects to see (to make the proper fueling adjustment). I imagine you will have to use the non-resistor jumper if you want to use the "zero" setting so as not to have the resistor in the stock circuit.

    The understandable frustration comes from people who waited a long time for their units to be delivered and have now discovered these units don't work correctly. Followed by more waiting for the correction part. (BTW, I bought 4, all of which need the correction part. I can :deal with it)

    Just my $.02

    Clear and concise. Thanks. Shame all the 1200 boys aren't getting the benefit immediately- it works a treat on my old banger!

    There are no resistors used in the IICE Air, nor the calibration board.

    "(The part shown is one of the thermistors on the Calibration plug-in.)"
    http://www.advrider.com/forums/showpost.php?p=23984664&postcount=1062

    Resistors simply can't work since they are a linear device and thermistors are non-linear.

    This means that non-linear curves are involved which are considerably more complicated.
    There will be more on this later.

    Thanks very much for what is for me the first cogent explanation I have heard on the "issues" concerning the need for a calibration correction. And I do understand, as you said, that the IICE Air used thermistors, but had no idea of the complication created in conjunction with the BMW ECU values and the reason why the -30 still gives more fuel and hence in my terminology a richer mixture when needed.

    Thanks again MJS for the breakdown of the issues...and for the record I have two IICE Airs and will buy the digital updated devices when they become available..:wink:

    Good to know it's not just an add on resistor, for the reason you mentioned. Is this now going to be two thermistors in series with the calibration part?

    Since it’s a non-linear device we are matching, over a wide temperature range, it is much more complicated than "two thermistors in series".

    This will be explained more fully in due course.

    JJ
    ps.
    And in that link to Poolsides post, did you see the actual part in the picture?
    Some will understand what is involved in dealing with using parts the size of grains of salt.

    <BR>Ok, today I'm ordering what I'm confident is the final version of the Calibration board. It will be nice to get these little gems built&#8202;!

    I would rather even read another GB Shaw quote than this "FLS". Once again, I do not know if you are being jocular or this is 'lawyering up'! :lol3

    Good news, I'm glad we're one step closer to digital bliss.
    :lol3 I get it. Didja have to run this past Marketing first, or just Legal?

    I just happened to be reading a press release and it just struck me as funny in this context.


    And of course it called out the usual clerics.&#8194;:wink:

    Funny in the context of the group of 10 or so of you admirers.

    You fellows aren't really questioning me. You're just causing trouble while we do what we can to move forward. And try and have a little fun while we do it.

    I post a little update and your network swings into action. Such devotion.

    The Calibration plug-in fixes the issue. Like I've said, I wish we'd have found it sooner but there were so many glowing reports from riders with R1200 models.

    I wonder how did they ever jetted their carburated bikes.

    Wearing my mod hat now,
    Bracky this is enough.

    STFU.

    Or it’s a ban.

    Is that clear enough for you?

    #14. Mod decisions are final.

    And as for the rest of the little group you associate with,
    #1. Harassing, intimidating or threatening other members is a no go.
