Does anyone have information what ECU can be remaped via data cable, not soldering other chip like in other cars

No, it's not possible, some newer motronics have this feature but 3.8.x does't.
Also AEB ECU's have write-once memory chips. Some people say that 1.8T AGU ECUs is compatible with AEB engine and they have rewritable chips.
