    HdeB in the Netherlands has fine tuned Todd's ECU map with the PCV on a Dyno.
    My Griso has a Quat-D exhaust with db killer but cat removed, open airfilter (Todd), Lamda removed (PCV kit) and shut off air from stepper motor.

    Here is the chart (Todd's standard ECU map in grey):

    Bike runs perfect now :D

    Klaas, thanks much for the post! He didn't by chance get a stock run of your bike, did he?

    No, we didn't have a stock ECU at hand (also exhaust and airbox were already non stock).

    Thanks, but not the same as he had my R/S exhaust on already. Big power numbers are fun, but I always like to remind every one of just how little one rides there. Most of the BIG benefits of my ECU or the PC-V come at normal throttle positions and RPMs. Regardless, thanks for posting/sharing, and most of all, the business!

    Agreed Todd, HdeB (Henk de Boer) worked 2 hours on the dyno adjusting my Griso for all throttle positions, not just for the "big numbers".
    There is a huge increase in driveability, far beyond the factory's and even your much better standard map.

    Yes very good, and something that AutoTune is capable of, beyond a small snap-shot in time. :silly:

    Auto tune is nice but all it can do is optimize your A/F mixture to a value it THINKS is best (preset for the target map), there is no feedback from the rear wheel (hp's). That's why I opted for the Dyno.

    Incorrect, but no need for debate... as long as you're happy, all is good!

    Damn, 40 more bhp than my G11, but I would just lose my license faster than I already am.....

    How high above sea level was the testing done and wnat was ambient temp that day?

    S'looking good though.

    Hi Klaas,
    The Netherlands are as flat as your bed... (at most places) and around sea level. Several parts are below sea level, that's why we are "famous" about our dikes and fights against the sea...
    But... ontopic again.
    Klaas, nice to read from another Dutchmen.
    You have a fantastic result on your bike , Klaas.
    I'm very jealous about it... :cool: I want that too!! That will come next year, I hope...
    Now my bikes are in a wintersleep.Till next spring.

    I'm sending you a pm, hoping you don't mind.

    16 meters above sea level, outside temp was 12 degree celsius.
    Inside cabin temp was 26,8 degree celsius, air pressure was 996,3 Bar.

    I forgot to mention that shifting gears is much more quiet now, also the driveline lash is less noticeable.

    That's the spirit!

    Nevertheless I would love to listen to dynamometer details: Inertial or Brake Dyno, model etc.

    On what # run was the black curve registered?
    Numbers are mostly .... numbers.
    If it has been the very first on a cold bike then you can look for 2-4 ponnies losing their way in the still cold tyre....
    If it has been the 6-7 run on a hot bike then you can look for 2-4 ponnies being evaporated in the too warm fuel tank...
    And so it goes...
    I mean that the actual number difference might really be much smaller and other drivability differences you experience riding around need time consuming response dyno runs to be more "objectively" assessed and not full throttle steady curves.

    So, to cut a long story short, if you are happy and it rides like a blast, all is good!

    112 hp seems super high. You either have the best FI tuner ever or the dyno reads high. You didn't do any head or cam changes?
    Can you share this map with us?

    John, that figure is perfectly feasible. The stock maps are super-rich up the top but I still managed to drag very close to 105 out of mine at altitude and on a fairly hot, dry day.

    Once the fuelling has been sorted this sort of top end figure is what I'd expect. Re-cammed and fueling properly I;d think that in good conditions 115+ isn't out of the question.

    I plugged in a wild ass guess at -10% full throttle with the 068 map you loaded. I would think it's ptretty close to optimum, but I don't see a 10% improvement. Prove me wrong... all I need is the new map. I've got a free dyno run coming up, so let's see that euro map ;)

    Run was done on a calibrated brake dyno, this one:

    More info (Dutch):

    I'm not going to share this map with people who don't trust my tuner, I have nothing to prove.
    Just thought it be fun to post the chart.

    Thanks for the info.
    I had no idea of Tovami dynamometers existence.
    Seems to be local business - no english web page, only dutch.
    Technically I see no ill points but even the best dyno is as good as its operator - nevertheless I see nothing suspect here and if Pete says this power is feasible then, why not? The shop/manufacturer seems to know their business.
    Even if the test was conducted at inertial mode, with such a big inertia drum it is pretty close to braked conditions.

    If you feel like talking more on the test I would like to place more questions:
    In what gear was this power delivered? Do you remember how much time it took for a test to be completed? Around 10 seconds or more?
    They mention about wheel slippage in their page (google translation).
    Is it accounted for in the graph? Measured by some means by the bench?

    (Please note I'm a tech support guy for another dyno firm).
