This is the US Penner map. You should see it in your downloads folder as Rocket R USA Full Power 31029.hex. The map identifier shows 31019 because that’s the base map. I don’t see why it should matter what folder the map is stored in but maybe it does. Do this. When you hit open under maps, choose Download in the lower left. This takes you to the developer’s web site where you see a list of brands, then models. Get to your vin for the R. The map will be 31019. Open it. Then save it. The app will prompt you to create a subfolder under maps to save it to. Do it. Now open the Penner map from downloads and save it to your new subfolder under maps. Open Penner from there. Now hit compare and load 31019. Scroll through the tables to see where the maps differ.
Did you register your model correctly when you registered the app or the first time you connected?
Do you have an Android device with enough RAM (at least 4 GB)? Do you have the OBDLink LX or MX+? Did you get the OBDLink app on your device and upgrade the firmware on your Bluetooth module?
13.9 v sounds ok. Did you remove the headlight fuse?
