Once you go into open loop in the ECU, there is very little if any learning that takes place. Subarus use a very active ignition system. Where as most other ECU's use fixed timing numbers and wait for knock to occur to remove timing. This is in no was a learning feature. Just a reaction to a cause.

Interesting. I was always told the Bosch ME9 unit for the 2.0T FSI motor was pretty advanced compared to other ECU's. I'm pretty impressed with the TCU in the DSG and it's ability to adapt to driving styles if nothing else. Not sure who manufactures that though. I'd imagine there is some reason for a basic tune being sold by all the companies instead of car specific tunes like most other cars. It could just be for profit reasons for all I know
