So after two weeks of using auto-tune and the PCV on my 12 I'm extremely pleased. Set the changes to +/-20% and the bike is SUPER smooth everywhere with more power than I know what to do with. This is definitely how the bike should be.
One thing I ran in to was a problem I can only attribute to air-reversion in the system due to the muzzy exhaust. In first gear at 3000 and 3500 RPM and 5% and 10% throttle, the bike keeps wanting to add fuel. I was riding one day and all of a sudden it pogoed back and forth so badly from a stoplight I thought my front sprocket nut had taken a shit. When I looked at the map, the auto-tune had added 60% fuel to those cells! Fortunately, I saved the trimmed maps every day so I'd have a backup and was able to go back to a first gear map that worked well. After a few more maps to pinpoint the exact areas receiving too much fuel, I'll go to the AFR tables and shut those areas off and just hand tune them.
As far as mileage, I did a trip from Reno to Sacramento which is about 130 miles one way. Doing between 85 and 90 the whole way up the mountains then back down into Sacramento I hit JUST shy of 41mpg. For the first time, I got better fuel economy than my buddy on his stock blackbird. Coming back, I got 38mpg doing the same speed. This was with an AFR of 13.6 in the cruise range in sixth gear. If I set it to 14 or 14.2 I know I can get over 40mpg on long trips.
Around town, I'm at 28-29 but that's because I'm just enjoying the shit out of the smooth roll-on power. I've also got 1st and 2nd set to 13.2 and third set to 13.4 AFR. If I leaned those out more, I'm sure I'd get better mileage around town but wheres the fun in that? Some kid on a 600 might show up and think he's hot shit and I have to be ready. :evil:
All in all it's a great upgrade and well worth the time and money. I'm planning on doing my first drag runs this Friday so I'll see how it does then.
