Just had a go at doing some OBD11 mods (via apps initially)
Stop/Start deactivation - Did not work. Will have to look into that one
Lock / unlock acoustic conf - Works with a subtle chirp
Seat belt warning off - Works, initially did US which is six notifications, but this repeats each 30 sec, so fully off now.
Fan level on Auto - Works
Comfort turn signals - Works, set to 4
Scandinavian DDRL's - Work i think, need to check
All in all very easy to do, but beware it eats battery life!! Have a fully charged battery and or have the car running (some mods require car not to be running though).
I had plenty of credits from the 'Black Friday' pro deal.
A very good device for the amateur that has lost of functionality. Will give the long coding a go in the week.
