I have used both applications and coding with the OBD11, what is the problem with the apps?
It is easy to get additional free credits by clicking on the ads, you can literally get 100 credits a month!
Nothing, but some people prefer to have full control over what they are changing, whereas with apps you can't see exactly what is being changed in the background. I did use an app tonight to do the fan level led display when on auto.
Done so far:
Chirp on lock/unlock - long coded
Stop/start disable - long coded
Headlamp washers off - long coded
Enable fan level display on auto - app
Still to do:
Reverse lights full brightness - long coded
Coming home lights long coded
DRL 100% with headlights - long coded
Full brake lights - long code
