Been playing with this for a few tanks of gas.
I put the '13' tune on for fun, and went for a decent ride. Came back and looked at the trims and it did indeed pull some fuel out of some cells, but nowhere near as many or as much as I was expecting.
I have noticed the box seems to adjust trims very slowly. I am not sure if it needs to be in a certain cell for a certain amount of time before it will make a change, or in that cell a certain # of times.
DJ is just throwing a blanket of 13.2 on the whole maps other than cruise. Which is understandable for them as it is a safe even # anyone can put on the bike and run well without eating fuel or danger of going lean. Good compromise.
DJ's version of cruise leans the table out at 5% throttle from 4500rpm-redline, 10% throttle from 3500-4500, and 15% throttle from 4500-5000.
None of that makes sense to me.
I am trying to watch my throttle position VS rpm as I am riding to make a mental note of where I want to tailor my tune. My version of light throttle cruise, regardless of in town or on the highway is basically 2-3k tops. Maybe the 5 speed bikes are reving higher?
I even have +2 on my rear sprocket and still cruise much lower rpm area than dynojet is tuning for.
They also aren't leaning out much for cruise- only 13.6 which is still fairly rich for fuel economy...and remember the actual areas we seem to be cruising in they are still at 13.2
On the other end of the scale, once on the throttle and we all know the butt dyno can be completely wrong, but the bike seems to feel better to me the more fuel I give it. I'm currently working my map richer the more the throttle and rpm increase, peaking at 12.8 a/f.
Since we are air cooled, I would much rather have a little more fuel to hopefully keep temps down a bit.
I am going to bite the bullet and buy the POD dash display accessory for this system so I can watch throttle/rpm/af in real time while I am riding to further dial this in.
Here are some charts I've been looking at.
