Ok, so I've been riding around for a few days with these installed.
There are 2 base files on the Dynojet site-
2013 stock bike.
2014 w/ slip on.
Just so everyone is on the same page, I'll rehash my understanding of the basics-
#1- the factory ecu tune on the 2013 and 2014 are different. There is a mention of it on the Honda website that discusses the technical build story of the CB1100. They mention the difference when they talk about the change to 6 gears. They do NOT give detail on which maps change- fuel, spark, throttle response (opening of tb blades)...etc
#2- the desired 'tune' of both the files on the dynojet site are 100% the same as far as the a/f target table. The fuel trim table results are way different but the goal they are trying to achieve was simply carried over.
The target table is pretty basic- they threw 13.2 on the whole thing, pretty much all RPM and throttle position and then just leaned out a few cells in what they would consider the cruise rpm and light throttle position.
~~~~~~~~~~~~~~~~~~~~~
So my bike is a '14, I started with the '14 file on the site. I've rode around and applied trims several times.
While the exact numbers in the fuel table are naturally different given my addition of the arrow header and modified velocity stacks, the overall look is the same- adding and removing fuel in basically the same map areas. A lot of the cells are negative.
If you look at the applied fuel on the dynotjet '13 file' you will see it looks a lot different than the 14 and mine- it adds fuel everywhere, but remember the target a/f table is 100% the same.
SOOO- I am going to now load the '13' file onto my bike and see what happens. In theory since the target is the same, the autotune should start pulling a lot of fuel out and after I trim several times I should end up right back where I am now on the '14 file.
Anyone have any thoughts for sake of discussion?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Part 2-
Once I have settled on my selection of hardware parts puzzle- snorkels, velocity stacks, cams, juggle them around for best results and best fuel mapping- I intend on hooking up the speed sensor to the autotune and letting it map fueling for each gear individually. I don't think I have seen anyone take advantage of that feature yet?
