this is not definitive and I am not an authority in any way. Your experience may differ and your results may vary. That said, here is what I think I have learned about the AP settings and why I set them the way I do.
The reason I set my sensitivity to 20 is because I find myself always adjusting the throttle while I ride.... and the more sensitive the setting.. the easier it is for a small adjustment to the throttle to cause the PC3 to squirt a rich shot.. and in my case that would be constantly. I like to go faster than the speed limit in most places.. (I'm sure no else here does this?
) and I am always in the cross hair
of the fuzz.. so I speed up.. slow down.. speed up.. slow down. It's like fighting my inner
. Plus, I feel safer as a pass traffic rather than pacing or being passed. So I opt for less sensitive. A quick snap open of the throttle will still cause the rich shot regardless of your sensitivity setting. So a lower setting here, seems to me, saves fuel unless you need the juice turned on.
I set the +5 to 10% just to give it a conservative rich shot. To be honest.. I can't really tell a huge difference on this setting until I get over 20%.. then it's a a real pisser as the engine looses power. Over 20% may be way too rich?... I'm thinking yes.
RPM Duration for fuel change:
I have tried 20 and 40... and people, I can't feel a difference. Obviously you have to have some number plugged in there or what would be the point? You can, of course, set it to anything from 1 to 40. Based on 10000 RPM red-line, give or take where you are comfortable shifting, 40 RPM would only be .4% of the total available RPM range. 20 would be .2, 10 would be .1% and a 5 RPM setting would be a .05% duration of available RPM scale. I figure what the hell and just set it to it's max.. 40 RPM. Tell ya what.. get your bike up to your favorite speed and in your favorite gear. then slow the engine by 40 RPM.. or wait.. increase it by 40 RPM... and good luck. 40 RPM is .4%. Here is another way to look at it. When I have the PC3 connected to my computer and I watch the throttle position change.... I can't adjust it in as fine as a 1% resolution let alone .4%. It's like 2%, 5% 10% etc... So if I can't adjust the thing that controls the RPM at this fine of a resolution, what's the point of this adjustment? Seems like it should be just on or off with the AP feature?
My conclusion is that the setting with the most user noticeable impact would be the sensitivity, with the amount of fuel change running in second place as long as you don't over fuel.. then it could impact negatively. I spoke with at least 2 people at DynoJet about the AP feature. One guy could only tell me it was a "rider preference" thing... which is basically in the manual, right? The second guy explained to me a little better and helped me understand the that the fuel change was X% over whatever the current fuel delivery is for that RPM at that throttle position, etc. This helped me, at the very least, formulate a logical understanding of what it is doing when I use the AP feature. I can't say I have found the best setting yet.. but I have found a few bad ones.
