Just a quick question, I have read the thread and cant see how you can expect to have 2+ cars properly mapped, datalogged and signed off on one Saturday Morning, let alone 5 or 10? The ME9 that the tfsi uses takes 25 mins to read and 20 mins to write, takes a good 45 mins to create a base map to test and 20 mins to datalog. Then if changes are required to the map, say 15 mins to do this and another 20 minute upload to the ECU.
So if the map is 100% right first time it will still take approx 2 hours.....
Hopefully this is a typo?
