Hi there! Congrats with your L405. I am still 1-2 inches away from getting to success with my 2016-LR4 L319, though HW, IID-Tool and the official LR Tester now see ACC (and we enabled all key settings with Patrick Meilleur’s help).Status: Was able to finally install this over the weekend on my L405. Thanks to the help in this thread, the whole process only took about two hours start to finish.
Was a little nervous running the CCF changes and upload but it all went without a hitch. (Side note: it's so cool to see the car shut off and fully restart itself without any intervention during the upload process! Makes me wonder if I could enable remote start...anyone know?) Calibration was simple using a local highway...took exactly 7 miles to complete.
The system seems to be working great, although I haven't had the nerve to test the forward alert function yet.
