    Never done a 2mb PCM, but if it is an issue I'll have Mark M fix it.

    Can't do scan or editing? Editing needs multiple checksums in same cal? Could do some workarounds such as multiple definitions for each section of cal, or could write separate program like old time Tunercat checksum utility for OBDI. That is, if a fix is not forthcoming.

    Fixed, but we have threads for bins by year if you'd like to add them.

    I have over 1000 files and most are bin files. We have a private repository of tuned and Good OE bin files that we use when we repair PCM and ECM's. They are all linked up, so if Tom adds a bin it will show on my laptop or desktop.

    Can you find the checksums without EFILive? I can find them all and the CVN's within a few minutes
