power steering

so my brother snagged a 2014 700 eps for 7100 from a dealer that wanted the room for 2016’s, they only had 1 and it was still in the crate.
I rode it on pavement, and boy I sure like the power steering over my 2012, just a little speculation, if 1 were to some how get hold of a 2014 or newer power steering controller (same part no. for 14,15 and 16) I’m thinking that would give 1 the same ps mapping as the newer machines, or maybe there is some way to "flash the old controller to give the improved steering.
the pn for the power steering actuator is the same from 08 on. the ps controllers are all the same price, around 800 new.
