    Thats how GM set the lower limit on pretty much any pcm since 2004. In our E38 & E40 custom operating systems we've modified the code to go down to around 160F.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    No I'm saying GM has a lower limit of 192 in the stock operating system. Nothing more.

    If you want to check out the custom operating system simply apply it to the file and take a look. Doesn't cost any credits to apply it to the file. Only when you want to WRITE it to the pcm.

    Then you will need one of HPTs Custom OS as far as I can tell.

    As stated, several times in this thread, you would need to apply the custom operating system under the os tab.
