Caught the Bug
Well, I just tried this after completely returning mine to stock with the superchips. I adjusted axle ratio and tire size which caused mine to go into limp mode. I even tried programming three times without success. This is the OBD adapter I bought to use with my iPhone 7. It connected fine, but even with the CEL on, the app wouldn’t read the code.
There are only a handful of adapters that the app developers have tested and verified to work correctly. I think most that are the same style as you have won’t work. I have one very similar and it won’t work. I ended up with the Vgate icar pro. Its the second one on this list.
