as others have said...do a back up of your as built settings

commit 1 change at a time...test it....then move on to the other changes.

if you screw something up, you can easily back out that change when doing 1 at a time. vs trying to figure out Wich change messed things up if you do multiple changes at a time.

This.

I didn’t have a windows laptop at the time so I bought the originally recommended, inexpensive tablet. Although it worked, the screen was small and resolution not the best ... difficult to read would be an understatement.
So I ended up doing one of the mods wrong - I think it was Lincoln mirrors but who knows now. Fortunately, I hand wrote the originals down and was able to revert back. Got a magnifying glass and found my mistake.

Also, once you have your changes, and confirm they all work and no ill side effects, another backup isn’t a bad idea.

are you guys still using the cheat sheet with codes, or changing the setting via the new forscan way ?

I use the old ways. It’s worked for Sicilians for a thousand years.

Wise words right there ! This practice should be used anytime you do ANY type of mod, engine, suspension ect…
Glad you’re getting it worked out though
