    Does 2 Bar Upgrade Lock ECM to HP Tuners?

    I have the VCM Pro Suite and it has the 2 Bar OS. Is the ECM now locked to only be tuned by HP Tuners?

    No it's not "locked". But I have tried to read an EFI Live multi bar SD tune with HPT and couldn't so I would imagine the opposite is true. But anyone with HPT should be able to read/write your PCM.

    basically yes, we change the OS ID to our own number that will not be identified by other software. In some cases they will be able to read your tune but not open it. The reverse it true for other vendors custom OS's.

    So for example if I take my whipple'd 2010 camaro manual trans to the dealer for some kind of chassis warranty and have to leave it overnight or a week, there is really no way they can remove my 1500rpm rev limiter (that I would apply before taking to the dealer so the tech's dont Ferris Beuler me)?

    Since I have larger 63lb/hr injectors, I figure worse case is they factory flash it, then it simply wont start since the fuel rate will be very low.

    If they flashed over it via tech 2 yes your tune would be gone.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Good, thanks. Actually I realize in my case flashing back to stock would flood the engine out trying to start it.. but that's ok too.
