Submission + - Toyota Sudden Acceleration Report can be Unredacte (cryptographyengineering.com)

dachshund writes: You may remember a year or two ago, Toyota vehicles were having problems with sudden acceleration. Earlier this year, NASA and NHTSA systematically reviewed the engine control code and cleared them. Or maybe not. You see, the report they wrote was heavily redacted. However, it appears that the redaction wasn't done right, and the missing pieces can be recovered simply by copying and pasting from the cached versions of the PDF files. These reports are really begging for a crowdsourced reading. Some of the details certainly raise my interest. For example:

Any duty command from the PID controller greater than or equal to 88% will perpetually open the throttle and lead to WOT [wide open throttle]. This also means that any duty greater than 88% will be interpreted by the hardware as a 100% duty command.
