DIC programming
Did a couple of searches but didnt see this mentioned before.
When you insert your key and turn it to "ON" you get the "Corvette by Chevrolet" message that scrolls across your DIC. (that didnt sound good did it?)
I noticed when sitting in my cars twin at the dealer the other day when you turned it on it said "Welcome to So & So Chevrolet".
Is this a dealer only access field, or has someone figured out how to put our own messages in there? Could be fun.

Messages on DIC
The messages are stored in nonvolitle ROM in the BCM (I BELIEVE).
On a Cadillac you can have two different names or any other combo of words pop up depending on which RKE fob is used. Someone who knows where this alphanumeric text is stored could replace the existing text with other text. A million years ago when I worked for a LARGE computer company I played around with replacing the console messages output for IPLs (Initial Program Loads) and for some other information and error messages. This was inside a lab and the messages meant no harm to anyone but were a break in the tedium of writing diagnostic programs. Given the proper tools and maybe a scan 2 or ROM burner the Corvette message could easily be replaced.
When I owned an ORIGINAL PCAT which did not support the "NEW" 3 1/2 " diskette drives I had someone burn an EPROM which had the codes to allow this peripheral to be used on the older PC. It was
"UNSUPPORATED" but it WORKED.
Perhaps someone who KNOWS will tell us what needs to be done to skywrite other messages or change the messages now showing up on the DIC to anything your heart desires.

has been beaten already-I believe the consensus was it's not possible on the C5.
