Ecu not cpu
But website isn't finished yet.
Only OBD plug. Small, hidden under cover.
Simplest version called "DPF Monitor Lite", which gives only dpf status, it's ~60euro.
How it works? Like I said. If you want check particulate mass (1st position on photo is 31.51%
) you must push together "up" and "+" buttons on steering wheel. Screen will change like on video (0:06). Back to normal lcd state in the same way.
If car will start dpf regeneration, screen with parameters will appear 'immediately'.
More advanced version will be more expensive. What functions do you need/want?
Text in the photo:
