I'm using an arduino to talk to my iphone and the can bus shield to display the track info and still be able to use the steering controls... The arduino talking to the iphone was easy just waiting on the can shield to arrive to test the next bit.
Flashing the vim stuff over obd is way over my head... While I'm waiting for the can bus I'm trying to find the vim location in the EEPROM to flash with my programmer.
Also just wanted to say what awesome work you and the guys have done here.
Thanks !!!
Ben

Ahh k. Well 29bit is what you want to look at and check out the "GMLAN Bible". You will get more info for what you are doing from that then anything else. GMW3110-2010 is all 11bit and not what your looking for

If you are having problems flashing the HVAC Module instead of removing the chip just lift pin 8 (VCC) from the board.
Mine flashes perfect.

Ok this weekend I am going to start looking for the elusive VIM location.
I have desoldered the eeprom from the main board and added some wires and socket so I can change the eeprom
over quickly while I test.
I am going to use the following assumptions from what I have read here an some guesses.
1. VIM is stored as 2 bytes
2. The stored value is related to the speed that the cars turns the screen off( mine is 3 kph)
3. This value is stored as plain text ?? maybe as hex?? decimal ??
4. To disable VIM change the stored value from 3 kph to 200 kph
5. Its in the second half of the eeprom ( Thanks Jezzab)
6. the reverse enable is probably stored close by.
I'll let you know how I go.
