I have observed the same thing. I find that the throttle on my 959 gets incredibly twitchy at about 10-20% throttle.
The best I can describe it is that at that point, its no longer a linear throttle and almost as if there's a point near 10% throttle that just feels there's a jump in the mapping. As an example, its like throttle position 0-9% maps to 0-1% throttle, then between 9-10% throttle position, it goes jumps to 10%.
I'm running with engine high, ebc at 3. Similar to your other post, I'm going to try the Sport's engine medium to see if maybe the throttle mapping is completely linear.
I can't find in the manual where it differentiates between engine HIGH/MED/LOW (pg 124 probably closest), but I'm under the impression that HIGH/MED are both full powered, but maybe HIGH has a quicker ramp up throttle mapping. My hypothesis is that maybe MED is a purely linear throttle mapping to 100%. I would imagine that the LOW mode is simply a 0-67% throttle mapping to achieve the rumored 100HP.
