Unfortunately I sold my car about two months ago for a good cause. I'm finally buying my own house (you can expect lots of projects in the near future while I make my house full internet connected).
I also changed jobs and on the last couple months I've been working 10 to 12 hours a day (no time for my projects). I can't spend more than an hour a week on it, which made my progress very slow.
I will update my GIT next week with the last Arduino and Android code.
In the mean time I'm making some researches on BUS injections to make it fit most cars/makes via OBD II/ISO port right out of the box.
