Sorry for being Tardy but been away getting stabbed in preparation for an op. To answer some points
1) Getting parallels won't work as no usb accessibility to ECU because
2) Although I have the adapter cable it's usb (as supplied by emerald) and my MacBook does not have USB access
3) I'm reticent to buy a 'cheap laptop' for the once in 20 years its needed I have enough plastic useless crud in my life
4) Dave at Interpro may be worth a shout as he's only an hour away. However many are of the opinion that only Dave at Emerald actually properly knows his ECU.
5) I'm near Frome so anyone able to help I'd be grateful
6) I actually don't know anyone with a windows laptop because a) I have very few friends and b) my friends are either very non tech or very tech (so this is all a bit old to them)
It's like a perfect storm of frustration, all because Emerald is not Mac compatible and I'm unlucky in the friends department/too stupid myself
I can't see why the map would have changed so the plug in is to establish whether it's a fuel pressure issue, a duff sensor etc. I'll call Dave at interpro and see what he says.
Tiddy thank you for the offer. Where are you? A run out would be useful/therapeutic once it stops blooming raining
