New memory type for new PCM's

[N0DIH]

This is why we are going to have a heck of a hard time reading the code out of the newer cars...

But I hear Ross has some ideas on how to work around that....

It's not problem, GM's new generation ECM's (E39 & E78) which of course we already support have the flash memory built in to the CPU, so I guess we are good for a few more years. The only issue we face is like what GM have done on the LML ECM where reading via the OBD-II port is non functional.

Bwahahaha, that's a classic! I love the cooling requirements and the block diagram, not to mention the "Number of pins remaining vs. Number of socket insertions" graph.

Yeah that cracked me up too.... I used to write specs off datasheets like this, so reading this is hilarious!

lol... each paragraph is roflmao material.



that's ideal for military applications, keeps the operating data secret.

Robert Pease is a good engineer with a good sense of humour, I have been following his columns for years.

For a second I thought that this was a real topic. I've seen that before about a year ago when designing some stuff... Unfortunately I've heard bus encryption is something the computer industry is either using or working on... doubt anyone would have a good reason to use it on real time hardware though.
