I read this file out of a 2004 6.0 truck it runs on gasoline and CNG. In the cab it has a switch to toggle off gas to CNG and is integrated into the GM ecm no piggyback and done by Quantum Technologies . Maybe this file can be used to use a switchable tune?? 12760

Thanks for sharing the file, but there is little chance we will re-visit custom OS's on the LS1 PCM.

No problem saw that it was a unique vehicle and if it could help.
