Document your changes
Backups, Backups, Backups
I work in IT and see people play whack-a-mole with changes (they don’t fully understand) trying to solve a problem, and have no idea what all they’ve changed or in what order when they finally decide to start over at square one. “Professionals”…..SMH
I have my As-Built file (from Ford) saved, as well as made and archived backups of every module before I ever made the first change in Forscan.
I use a spreadsheet to document every single change I’ve made, the module, the before/after setting, the date and mileage.
I make and archive on my PC, a backup of the impacted module(s) after each change, saved with date stamp in file name.
Take your time, use caution, understand the changes your making, and have the ability to get back to where you were if needed.
