Pardon me Tim, this is a end user point of view and is almost trivial ....

After years programming C/C++ on Posix systems (Embedded sys and Desktop) i can say that this is likely the same recurrent issues we have to face. So IMHO there is no special book helping us to become a better programmer, just read code, copy, experiment new implementations ... and refine our skills, forget and relearning all by another way ... It take years. Habib

There are many other options as well for location. The processing power of the engine controllers is impressive most of the production cars have multiprocessors one of which is similar to a PowerPC.

Toyota now probably wish they had not push this "drive by wire" technology too hard.

It *can't* possibly be the electronics at fault... (yeah, sure) I wonder what the legal consequences would be of someone reverse engineering one of these controllers *and* the black box/log. I suspect you would end up spending lots of money being harassed! :<

The idea that you would have to buy (and fit) a completely new engine because one of the controlling processors dies just doesn't make sense. tim |
