There is no doubt some learning curve.

There will be a lot of duplicates of DME and transmission modules etc so you need to learn which apply to you and remember.

For the voltage and rpm graph I picked BMW from first menu then auto sel Vin then control module then top engine module. In the engine module pic engine operating Values then live data.

From live data scroll through the long list and find rpm and battery voltage and check both and view.

It will start in text then hit the middle button will say something like 1 graph then again 2 graph.

That's all from memory so I could have missed something.

Don't get too adventurous in the section where you can reset things like the transmission until you need to. Eg set the air suspension to deliver mode etc. Some reset procedures have no cancel option when past a point of no return
