    Save as .tun and not .ctz?

    Is there a way to change a .ctz to a .tun or do i just need to use version 7.2 for everything?
    Only ever used as a scantool,now trying to tune something with it and just not very familiar with it.

    Not sure how,but I have like 3/4 versions of efi on laptop.
    one is 7.2-saves as .tun but won't open a .ctz
    7.5 won't save as .tun and then there is v8 and another one floating somewhere.
    v7.5 is what I read with and use.
    Really should have familiarized myself with it first,bought a truck specifically to figure it out but trying to get a driveable tune on this huge cammed truck today/tomorrow.

    Try "save as" with .tun on the end.
    so far seems to be a winner in V7.5

    ps,your inbox is full
