Dear all,

Is anyone having some experience with bmw cars tuning and wants to share?
Lately I am curious about this topic, bought ca kess v2 chinese clone (red motherboard) if that matters.
I red the map, save it and opened in some old version of ECM Titanium.
I have tried to understand the principle of modifying maps without too much success because there is not much documentation available.
For start i will try to buy a map OEM with EGR off - intention is to leave existent new EGR in place but too see how that affects the regenerations intervals on the DPF.
Then i will be curious about stage1 - just to see how if the filing to drive it is different.
Good part about tuning i think is that every time you can go back to the OEM map if something is not ok.
Two things not clear at the moment - is ECU safe to be written with kess v2 chinese version? EDC17C02 i understood is the type and the second - will BMW ista updates - overwrite the modified maps back to original?
To be well understood - is not about to save some money; is more about understanding and learning something about which i am curious. 

Thank you!
