I would love to see some AT code scripts for the MK2 for things like:
1. VIN setting and retrieving
2. Incrementally raising and lowering things like RPM so I can see them move on an OBD reader
3. Simulating real-life engine conditions as much as possible by varying things that typically go together, like tracking rpm upwards as speed goes up, then dipping rpm to simulate a shift as speed continues to climb, etc.
4. Other interesting things.
I think it would be great to have some common community recipes like this to be able to start the new folks out with existing interesting data.
