So I'm preparing my knowledge to code the car myself. I purchased a cable on Ebay and got an instruction from here http://www.bmwesys.com/guides/

In this guide they use E-Sys 3.26 and ESysLauncher 2.3.0

I also found another guide with E-Sys 3.27 and ESysLauncher 2.4.3

Both provides very clear steps, however the one on top tells me to use "READ (ECU)" and the one below uses "Read (VCM)".

I wonder what do they mean?

Thanks all

ECU - engine control unit
VCM - vehicle control module

Our man Knightsabers has put together a coding tutorial which you can find here.

I followed shawnsheridan's guide and successfully coded my F30 2015. Some names are changed but still figured out. Thanks Shawn

I thought VCM was Vehicle Configuration Management.

ECU is electronic control unit. Each module we code in ESYS : DME, EGS, KOMBI, FEM_BODY, REM, etc are all considered to be ECUs. The engine ECU is the DME Digital Motor Electronics.
This confused me quite a bit at the start as well.

So which one we need to use? Do we get the same info from them.
Why there is people using EDC and other VCM. I'm confuse now.

I can only add that I always "Read ECU"
