If you upload the new alpha firmware that Terry is testing, the JB4's new learning logic is enabled on all the maps but is only used for boost targeting on map 5, and it does not reset itself when switching maps.

And BTW, the new map 5 while running 30-40% E85 mixed in with 93 pump gas is insanely fast and very smooth!
I'd say its every bit as quick as the older map 3 even when running meth!
