Also curious on this subject. I understand that the canned maps generally work very well, but from what I know they are fixed air/fuel ratios and changes in altitude, riding style, and other factors make no difference. Does it matter? I'm at sea level, but plan on riding to Denver once a year or more. Will my bike run different at altitude if I don't have the auto tune?

I had the PCiii before I got the PCV with autotune. I changed my cams, tried to get the PCiii tuned and got it close. I decided on the PCV with autotune. Jamie from Fuel Moto sent it with his map for my combination. The bike ran pretty well with that setup, but I noticed as I rode, the autotune dialed it in closer. I checked it with my laptop and was able to see at various points of the map, the changes the autotune caused to bring it to the ideal fuel mixture. The nice thing about getting the PCV, you can get it first, and add the autotune later after saving some lunch money. I did some checking around, and the price at Fuel Moto was a little cheaper, the extra year warranty and future support for tuning was an added bonus.

From my research prior to my purchase of the PC5....
It works fine without autotune. But not ideal.
Canned maps... ignore these....
If you buy from FUELMOTOUSA.com... they give you unlimited lifetime map support and double the warranty. Making no need for canned maps, they will design one for your bike and modifications like they did for me.
Plus they are up to $100 cheaper then other sites.
I got mine for $300 including shipping.
Check them out. Trust me, no canned maps. Mine works awesome. Noticeable improvement and I didnt have to pay hundreds for someone to design a map for me in addition to the pc5

You still are getting a "canned" map! Did they dyno your bike? If not, its a canned map.

Keep in mind that EPA regs are very strict and every bike must meet them before sale. At the factory all bikes are equipped with the same map, not custom tuned, so if there was a wide or even a moderate variance between bikes they would need to do custom tunes on every bike to meet EPA regs. The same logic holds true for PCV maps.
Jamie at Fuel Moto, as well as several other experienced tuners I've spoken with, say that there is little variance between bikes. That's why I think the basic PCV from Fuel Moto is right for most people, the exception being the obsessed tweaker (like me) or someone who plans on making changes to their configuration (cams, etc.). In either case AT would be a good investment, as in the latter situation you can avoid a dyno-tune after each upgrade.

The value of this is that with the ą values in the base map you don't know exactly what AFR the ECM is providing at a given point and any changes to the map is guesswork. This is not necessarily a negative quality, as I did that obsessively when I had the PCIII and basic PCV. You can fine-tune the map for mileage using the seat-of-the-pants methodology--i.e., feel and listen. If you start leaning the cruise range for mileage, for example, if you hear detonation or experience hesitation you know you've gone too far. Thus, either richen the values or retard the timing in the area where you're hearing the detonation until the condition stops.
