Upgrading OS

[Naf]

HI all,

I am in the process of upgrading the engine in my tahoe from a 5.3 to a 5.7 However, i am runnin into OS conflicts. My tahoe has an older OS then the other vehicle in which i am takin the engine.

With V1, is it possible to upgrade the OS from 12587811 to 12592433?

Lookin forward to your replies

If you have the commercial version, yes you can upgrade the OS through a full flash. Just make sure your PCM is compatible with the OS you want to use. A few other members on here would be able to help you with that...
