I'm not very familiar with CAX files, and what you can do with them. But, I have a 1MB OS, on my 2004 GTO PCM. There is no COS5 available, and EFI Live is not willing to develop one, (I even offered to pay for it). Can a cax file be used to basically make my own COS5? Right now I'm using COS3, but I really want the COS5 features. If someone is willing to make me a COS5 I would be willing to pay you. I just don't have the knowhow.

Just because it looked cool.
