It all sounds vague to me at this point.

depending on which one you have in your ride will determine whether or not they have actually hacked it or not.
1. This statement says they hacked one of the two ECU's. Is this a guess or is that confirmed 100%? And which one?

2. Does "hacked" mean they gained access to the ROM (meaning they could read it), or that they gained CONTROL of the ECU?

2a. If so, what exactly can they control and how?

There are actually quite a few variations. From my experimentation the easiest one to hack at this time is the 2007 one, which required a firmware update as part of a TSB. Having that firmware file allowed me to easily find the area of the firmware that contains the maps. The problem though is the process of getting the modified firmware back into the ECM, due to the security measures that Toyota implements.
