Make sure that you "Read" and save off a copy of your existing map, before you do anything else! I also recommend popping off the plastic cover on the back of the gauge cluster and unplugging your headlights, so that you don't draw as much power from your battery. Make sure the batter is topped off with a battery tender before starting. The last thing you want is to be flashing the new map and have the power drop and shut down and you hose things.
That all out of the way...
Mapping this bike can be a pain. TuneECU is great, and it is free, but it is not as easy as dropping in a Power Commander. Part of that is that you have to tune by trial and error. You do a sweep of a given range, and then you make educated guesses and trim the fuel tables with the TRIM tab. But to test it, you have to shut down the motor, send(download) the new tables, turn off and on, restart, and then do another sweep on the dyno. Wash, rinse, repeat. It takes awhile. With a Power Commander, you sweep, it Tune-Link makes suggestions, it updates on the fly and you sweep again and repeat till it is perfect. Once you have a target AFR, then you can go into the areas that you want and hunt for power, etc...
Another fly in the ointment, is that the trim tables are not a percentage. They are supposed to be, but on this bike, they don't seem to work that way.
On a Dynojet unit, each time you increase a cell by "1" or "-1", you have the effect of moving the AFR .1
So if you wish to move the AFR from 14.3 to 13.3, you would enter a value of -10, and while it is not always an EXACT science, it does pretty much work that way in most cases.
On this thing, we found out that the ratio is about 3:1. You need to put a 3 in the trim table to move the AFR .1 So in the above example, it would take a value of -30 to move the AFR from 14.3 to 13.3
Again, might vary slighty from bike to bike, but this was what we saw on my bike, and it was repeatable and consitant throughout. We discovered this by making trim adjustments assuming it was based on % or something, and we saw spots where we trimmed +10 and so almost zero move on the AFR readings. So we started playing and found a consistent ratio that proved to hold up, and so our new trim values were based on that and verified and they held up.
Total pain in the ass. While TuneECU is free, and I love it, if you really want to tune the bike with zero hassle, get a PC-V. LOL
So, here is the result. The map info is at the top of the post, if you have a different VIN, you can copy the fuel tables into your map(make sure to post to ALL THREE fuel tables!)... I didn't play with ignition, but what settings I used are all in the above section.
Last item, is the crackling on decel. We forgot to do that part, so I added fuel to the 0% area to richen that up a bit... I remember seeing an AFR of around 18 or so, when it started crackling and popping when you cut the throttle and let it coast down to a stop on the dyno, just as it does on the road. Those settings on 0% are what I guessed at and trimmed and committed, so you compare your map, try it out, change it, whatever. I will try and ride it later and see how it does, but it should be a good starting point.
If in neutral, you rev it and it is slow to come back down to idle, then it is too rich, so back that area down to where it comes down to idle properly, but is still richer than the stock map, so that hopefully it will reduce the popping and banging a bit.
Enjoy!
