    I'd like to put a map from the 4.77 disc(.mt6) into a Ecm which already has a Sert map from the 4.12 (.mt5) disc.
    Does the ECM accept any file extension? Or, does it have to be the same file extension that was first put in it? Want to find out before I try this and maybe lock the ecm up. Thanks for any info.
