It's under "Tools" -> "Map Compare".
It can read in 2 different maps, let you view either one along with their air/fuel graphs,
do difference/delta comparisons, and averages between the two.
I'd like to take my stock map, average it with a fully-tuned map from a bike with
similar characteristics, save it, upload it to the bike, test it, and keep repeating the process
until I get it the best I can and then have the dyno guy put the finishing touches on it.
This methodology (hopefully) would get me very close to optimal performance and
cut down on the time and expense of the final dyno tune. Thats the plan now.
Without the ability to save the custom map with the averages I will have to hand enter
all the changes...
