    What can I turn off and modify in the toyota ecm?

    I'm looking into buying hptuners for some ls swap projects but the first thing I would like to use it for is my 2008 sequoia 5.7l.

    I'm wondering if it has these options in the Toyota ecm:

    -disable vats (chip key)?
    -disable second o2 sensors(after cats)?

    Also is there a sample file I can use to look over the options?

    Thanks

    Thanks for the reply! Unfortunately it appears that I need to have the mpvi2 connected before I can look over the file, thats a problem because I dont have the hardware yet

    Am I doing something wrong?

    I have almost the same exact question. Wondering if I will be able to switch off the EGR so I can delete it without having a check engine light on. (07 Tundra) I also tried to open the link after downloading VCM suite, but it will not open without hardware connected.
