Awesome mod. Just a note for anyone who is having problems with the track map, I found when I used the map generated by default, it wasn't accurate (ie my lat G peaks happened when the cursor was on a straight, etc).
Simply regenerate a map using the track editor and instead of using the GPS channel, use the lat G channel; choose closed circuit and it'll make a new map. This is when you're looking at the squiggly lines in i2Pro, NOT in AC itself.
