Neuf makes some great points. I did not think of those when I tried mine, but anyway....
I did it. I already owned the autotune, and was very happy with my flash, so why not plug it in and see what I get?
It was very frustrating. I dont know if you have worked with autotune, but its not near as seamless, wonderful and easy as it sounds. Its not very easy to find the AFR you are searching for. Do you use whats suggested, from dynojet? The numbers you find online?
Im probably being silly, but we are using this auto tune to try and find "perfection". How do you do that by the sensations your ass feels?....you know what i mean...? What if, on this bike 13.8 is better than 13.5?
If you start with a terrible fuel map, it works pretty well. You do notice the suggested changes the auto-tune is making, and we you accept them, the bike runs better.
But, when your base map is good, and all the other built in, ECU issues have been dealt with, its past the point where you want to tune by how it feels.
Unless I could book some serious dyno time, I would not bother with it on a decent reflash.
Thats not to say it cannot be improved upon, but you need more subjective info than just a page of -2 and +3's. Once you get to a point where you dont really feel the changes it suggests, why bother?
I did find it entertaining, but its as-if this autotune is one part of a three part solution, and you are missing the other two parts.
