Default How do you change the DIC Welcome Message?

I was reading on the C6 General Discussion forum about all the cool DIC Welcome Messages people programmed when they start their cars - can we do this on the C5 too? If so, what's the procedure? I used SEARCH but couldn't find anything

someone said you'd have to crack the ecu's code in order to do that. even if someone knew the code I'm sure GM would frown apon anyone reprogramming it.

Apparently its easy for the C6 guys to do without any special tools - its an option in the DIC. Too bad we don't have the same capability, you gotta check out some of the cool messages those guys came up with.

And Dennis Kucinich has seen UFO's ........

You may have seen a "Photoshop" picture where someone has super-imposed a new "message" in the picture ..... The C5 message is stored in the IPC; without an EEPROM burner, and a whole lot of information on where the message is located in memory, you can't change the message.

If you've seen it, ask the person who modified the message for the starting hex address that they found in the IPC memory for the message

Yes, but I find the DIC option that we have to be a lot more useful. The C6 guys can't extract OBD-II codes like we can.

I've seen video's of guys with a different display before the c6 was out

Not sure if it was a video edit or a tech2 mod or what

If its a trade off between the C5 DIC, which provides us OBD-II codes, vs. the C6 DIC that doesn't but lets you change the "Welcome Message".... I'll take the C5 DIC. Thanks.

Default If you can tune the eprom you can change ANYTHING

Burning a new code in an eprom isn't a major activity. Just need someone who knows the procedure. I burned new eproms on my PCAT over 10 years ago. If anone KNOWLEDGABLE here knows HOW to do it then thats that. Not rocket science. BIGHANK
