Very radical move what he's done , and far removed from what the topic is about but at the bottom of it all,the solution is there and most of the control problems with the standard 10 are down to budget,quality and restrictions for each country the bike is supplied to.Euro 4 being an example.
FT ECU is much better than standard programming but if i'm honest it's not the be all and end all.
