I am guessing you have been in contact with G56 Calum????
Certainly have...they've changed over to the Emerald K6 ECU recently and I've got one of (or the actual) first production one. Initially they had a bit of a cock up over the wiring of the production loom adapter which stopped it from firing up but that is sorted out now, it fired up no problem this afternoon with a revised adapter but the rain has been tipping down so I haven't been able to get out and see what it is really like. Did drive it gently for a few miles on the standard ECU at the start of the week to get its MOT done and it ran fine, a lot smoother at lower revs than with the standard cams but I wasn't keen on driving it properly without an appropriate map.
