Dynojet auto tune

[stoo]

Excuse my technical ignorance, can any one help with this question?
To run the auto tune you need a PC-V with some baseline map installed (correct??)
Say the map is for a stock bike with the Rotti air box.
Add an Akrapovic exhaust and go for a ride, Auto Tune adjusts fuel to match setting of installed map.

Wouldn't the air /fuel ratios be completely different for this set up as the map was only made for the air box addition and not the exhaust???
Or are we only expecting a "ball park " tune.
If 13:1 was good for full power and 13.4:1 great for economy etc every tune map would be the same.
Obviously I am missing something (probably a chromosome)
Dont reply too quickly as I am slow reader

Auto tune only provides (suggests if you like) setting which you have to save to your map which is overwritten at that time. So you would pick the closest map and autotune will provide a new table that will change the map and optimise it. If you don't save the suggested changes then the bike will keep running the map you loaded. You also have the option to manually tweak things if you want.

Make sense?

sort of
I would probably have to play with the PCv maps on my computer to fully get my head around it.
Thanks for the reply

I would pass on the Auto Tune. Take the money saved, add a couple more bucks and have someone dyno tune it. With the amount of money we blow on these bikes, it's not out of line.
