Well, I tried to be good and not post in this thread but I just can't resist. I have been running the Daytona Twin-Tech setup on my 124" build for about 15K miles. Here's my thoughts regarding the system and its "wide-band" sensors.
I absolutely love the flexibility that the software gives me. I can see and/or adjust anything and everything. I get great gas mileage and good performance from the setup.
Now for the downside. I know that the "autotune" will not be as performance perfect as a dyno'd bike. I am leaving some power on the table. My biggest complaint however is the inconsistencies. I can load a map and the bike will start easy, run well, etc., then it will randomly just go sour. Hard starting, running very rich, idle issues, etc. I reload my base map and the bike will run well again. I have quite a few cells at the bottom end "locked down" (don't autotune) trying to keep the idle issues from coming back but to no avail.
Bottom line is that I am frustrated with the system and if I didn't recently get laid off I would be replacing it with the Mastertune and getting it dyno'd. The autotune system is a great idea, it's just not ready for prime time yet...
