Revisions will be listed under 3 main categories, as shown in the numbering of the revision.
Example: R7.1.5
The first digit signifies a Major Revision/version
change/count. In this example, 7 would be the most recent of major
revisions. These numbers change when a major feature has been added or
updated (such as Advanced Launch Control or higher power output files).
The second digit signifies a minor revision/version
change/count or changes to files that are not considered major but are
noticeable in the overall performance and refinement of the car. In this
example, the 1 in R7.1.5 would mean that a minor change was added over
the base R7 file.
The third digit signifies a sub-revision/version
change/count or changes that are very minor/unnoticeable. These
adjustments are generally box-code specific adjustments or bug fixes
that change parameters of the tuning that most will never notice in
their day to day driving but refines the overall file by solving minor
bugs. In this example, the 5 in R7.1.5 would be the 5th minor
sub-revision to this file on this box code.
Note: Not every box code needs the same sub-revision
changes. Often they are box code specific and not necessary for every
box code. If there is no sub-revision number listed for your file on
your portal, then there is no need for an update in that category of the
patch.
