    Default CNG OS's?

    Recent project lead to some discussion about the CNG pickup trucks and what is in those OS's.

    https://forum.efilive.com/showthread...l-sensor-input

    Anyone have a copy of an OS from an LS1B PCM? Maybe a VIN # for a truck that was built with CNG? (roughly 2005, 2006 ...)

    Thanks

    I have an LS1B tune here with the OS 52371978 from 2002 (so the 512K PCM) that was for CNG. However I don't think we even support it.
    If you have access to TIS the VIN was - 1GCGK29U82E285529, you might be able to get some info on what was so special about it.
    I no longer monitor the forum, please either post your question or create a support ticket.
