The AT adjusts the fuel map but does it change any timing settings?

 

No, the AT does not adjust timing. Fuel only.

 

The auto tune gives piece of mind knowing that you are always running in the desired a/f ratio under all riding conditions. Dyno tunes are only good when the conditions match that of when the tune was done.

The object is to set the desired ratios and then ride. After some time, you can start adjusting the variance down so the auto tune has a limit as to how much it can adjust. This will prevent the unit from trying to compensate if a O2 sensor goes bad.

 

I just installed the pcv today and will do the at on Friday. I wanted to ride the bike a couple of days without the at so i would know it is working properly and know the difference between the 2.
Like iclick said if you are not a perfectionist you will not need the at.

I went from the fuelpak to the pcv because I added cams and they could not get a map that was close enough to make me happy.
Here is the run down.
I added the SE compensator Tuesday, I have been getting 39-41 mph real regularly. I got 42.6 mpg.
Today I added the pcv. better throttle response, smoother riding, engine running a lot cooler, and got 46 mpg. I did it with mixed riding, 20% in town, a lot of stop and go with picking up stuff, 50% back roads and 30% interstate.

If I had knew it would be this much better I would not have got the auto tune.
