As subject, does anybody have any experiance with the Yoshimura EMS system (like Power Commander but apparently better)?

Picked one up off eBay for around 1/3 the cost of a Power commander and whilst there are't as many maps available online, it is supposed to be a better system.

Anybody used/got one?

Mine will be on a 954 Fireblade engine but I guess pros/cons will be the same on any.
