    app for iOS that runs GM enhanced ?

    Update. DASH COMMAND made by auto meter ( the guage company ) works perfect for iOS. It’s $10 for generic and $10 in app purchase for full PIDs , well worth the money since torque isn’t available and seems like it never will be according to the posts on the torque forum

    @?$#& !!!! P0300

    I don’t have money to invest in a scanner right now , that’s what sucks. I even called innova to see if there was a way to unlock the full GM reading and there isn’t , only the 5160 pro can do it. Does the torque app give detailed info on a scan ?
