    Default Emission updated operating system on E98 controller not supported.

    I am trying to see if the update can be reverted back to the last operating system. The new operating system is not yet supported in the EFI Live v7.5 software. I was able to read the stock tune from the truck but cannot make changes to the tune in v7.5. Is it possible to full flash the old operating system so that I can make the changes I want?

    As long as you have the latest public release versions installed then you can revert back to the previous OS.
    By the end of the week we should have all the updated OS's supported as the reads have been getting sent in. These won't include CSP yet though.

    Cheers,

    Can you clarify this?
    Is changing OS's on E98 now possible?

    It always has been, but only on the same year model. Eg, you can't put a 2015 OS in to a 2017 vehicle.
