Line lock not showing up
 

sorry

Have you tried using Forscan and doing the settings yourself? Reasonably straightforward. Details on the Forscan site.

Just curious, but is launch control part of the automatic set up? I have a 2018 and use launch control but it is stick. Don't see how you can do that without a clutch.

Automatic equipped Mustangs do not have launch control but sorry no idea why the line lock feature is not showing in the Track Apps. Take a look at the owners manual??

I was worried about that failure to appear by the Line Lock, as well, but somehow when I needed it, there it was. Something to do with the ignition being on, transmission in gear, something like that.

User Manual:

Initiating Line Lock
The initiation stage verifies that the vehicle
is ready for line lock function, and confirms
driver intent. Follow the prompts in the
information display to initiate line lock.
The following conditions must be met to
initialize line lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is traveling less than
25 mph (40 km/h).
• Selectable drive mode is not in wet
mode (if equipped).
• There are no electronic stability control
faults.
If you want to cancel line lock once it is
initialized, press the left information
display control. Once initiated, line lock is
prepared for activation and remains
initiated up to 25 mph (40 km/h). If vehicle
speed exceeds 25 mph (40 km/h), line lock
automatically cancels.

Engaging Line Lock
Follow the prompts in the information
display to engage line lock after it is
initialized. To engage, firmly apply the
brakes. Then press the OK button. Once
engaged, release the brake pedal. The
front brakes remain applied and the rear
brakes release. At this point, the
engagement timer is initiated and shown
on the driver information display.
The following conditions must be met to
engage line lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is stopped.
• The parking brake is not applied.
• The driver door is closed.
• The transmission is in a forward gear.
• Selectable drive mode is not in wet
mode (if equipped).
• There are no electronic stability control
faults.
• The steering wheel must be in the
straight ahead position.
Releasing Line Lock
While line lock is engaged, you can exit
(release) the feature using the OK button.
When you press the OK button, line lock
releases immediately and normal vehicle
function resumes. When line lock engages,
a countdown timer shows the remaining
time before line lock is released
automatically. If you exceed the time limit,
or another vehicle condition requires line
lock to release, the system safely
disengages and normal vehicle function
resumes.
Note: If you apply the brake pedal while
line lock is engaged, line lock automatically
cancels and normal brake function resumes.

So it does work on car with Auto? That sounds good if so.

that usually means that the people who viewed the thread did not know the answer, but did not want to reply "I don't know" . . . LOL
