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. :hihi::hihi::hihi::hihi:



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

Write Only Memory :hihi:

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.
