Come back disconnect battery POS, remove DIC/INFO fuse, go make necessary file changes go back connect POS terminal, go get computer, connecto MPVI key on engine off door shut write file, key off door open, start truck, reinstall DIC/INFO fuse, connect WB/plug in, start scanner go make data log pull, for Ve/MAF this took about 30 minutes each time!!! Hope this helps someone out in the future!!! and I kid you not if it wasn't followed to a T it wouldn't write!!!
