You have to modify your SCT tuner with some files to get livewire working. Again not sure if the SCT will be able to read that information either. The dealer will be able to though.
To put into test mode, hold the left steering wheel Ok button, keep holding, turn the key to the 2nd accessory on position, keep holding until the message pops up on the screen, hit ok. I'm not sure what data it will give you though once you enter test mode (once in test mode you can start the engine).
Your dealer receipts should say what oil they used, or call them and ask for a new copy. I don't think anyone can be that stupid to put the wrong oil in.
Do you mind taking a pic of the gauges at warm idle?
