Did you read what I wrote?
YOU NEED TO FLASH YOUR ECU (IN YOUR ALLROAD) WITH 4Z7907551R! AFTER WHICH, IT SHOULD COME ALIVE!
THE A6 ECU IS NOT COMPATIBLE IN ANY WAY, SHAPE, OR FORM WITH YOUR CAR, OR YOUR FILE.
Seriously though, you cannot read the 551AA or 551S files with nefmoto or you will get a no start, and a programming not finished DTC. You need to write 551R back and it'll be fine.
