+1 for Torque, pay once and it does exactly what it's supposed to do and doesn't bother you with anything else.

I paid for a license of obd jscan for my vehicle since it is specific to Dodge/Jeep it can do everything, including activation of features and access to all data in the vehicle. I had to buy a more expensive vlink adapter, but it was only $20 or so. It has saved me tons of money so far. I was able to program keys, activate remote start (had to install a hood switch), and have been able to diagnose several issues with things like tpms and abs.

Used the free version, don't know why I updated to paid, WORTH IT ($5). I'll never not have a BT adapter ($4) on my car computer and Torque on hand. Worth it just to read check engine lights.

Wife's car occasionally throws, and sometimes clears, a minor emissions error, kills the cruise control. The passenger can reset it rolling down the interstate and we're back in business.
