If you had to survey a study group to learn that information, then Toyota may be more hopeless than I thought.

I believe that comment may have been specifically related to BMWs locked down DME/ECU. I've heard some things saying that there were internal discussions to make a more open engine management system so tuning was easier off the bat.

Full access to the B58 ECU happened just last week by some Russian developers. That's a long time after the cars release. Toyota/Lexus ECUs have been locked down for a while as well. We got lucky with the 86 because Subaru is more or less making open ECUs.
