Owners of a Plus 4 with the GDI-engine might have heard of the ECU flash that MMC offer. From all I could find so far, it seems that there are two update versions available:
1. "Enhancement" flash
2. "Clubsport" flash
The latter you can only get if you have the Aero Racing Clubposrt Exhaust System (
cross-referenced thread here).
One thing about this that bothers me is that I can't really tell which version of the flash I have; is anyone here knowledgeable about how to check the ECU version, for example by using an OBD-tool?
