Autolearning kits are just that; You install, They learn..., and leave the user fairly in the dark of what really happens 'under the hood'.
Perhaps great for the 'I just want to drive (to the sat.night meet and pull out the lawnchair)' folks, but anyone who likes to tinker with their engine tune and get more/most out of it should like to explore new grounds/learn new ways of improving the old.
