To do that job you will need to buy ECU explorer not BMW explorer and is not a VIN issue is a sync ISSUE.....

I heard that when there is sync issue the engine will not try to start.
When I try to start the car the engine cranks.
Is this means that sync between DME an CAS is not the issue ?

In Esys I noticed that DME lack of CAFD.
   
Is this could cause the engine to not starting ?

In esys click on "DME2 [12]" than click on "Detect CAF..." than choose CAF file and code DME, but you will still have to synch ISN number CAS-DME to start engine.

Several modules with your ISN and VIN must match up internally to start the car, you may be able to get the trans into neutral and power to the ignition to crank, but if you don't have the EKPS (electronic fuel pump module in F3X, idk the F10 equivalent) matching up with the DME and the gearbox module the fuel will never flow and then you can crank all day but never start because the fuel pump is disabled.

You need to use your old DME . becuase you need macth ISN between FEM and DME for the car starting

or find the way to change ISN in FEM to macth new DME and Change DME VIN too

Yes, with old DME engine started. It was working few times. But now the engine starts and immediatly stops.

Maybe this is the issue with injectors, because as I understand that the injectors from new engine should be written and adapted in old DME

Also I have another issue.
Old engine have turbo with vacuum control from vacuum pump.
New engine lacks of vacuum line to the turbo, to turbo there is additional wiring, so the turbo is electronically controlled from DME.

Is it possible to code the old DME for controlling turbo by wire ?

It sounds like you are trying to convert a PWG car to EWG. The 2 are incompatible and I have not found any instance of anyone being successful with such a swap yet. Your case is different since your changing so many components but it has not been done yet to my knowledge.

Are both DME with same part number, HW number? If yes. You may use old DME and change type key in FA. Load modified FA to caculate suitable swfl,cafd..then flash it.

Both DME looks exactly the same, but numbers on them are different.
The DME from old engine:
   
The DME from new engine:
   

How the type (PWG and EWG) is represented in FA??

It is not compatible for original and replaced DME
1: You have to read out DME VIN from replaced engine. Use BMW explore or ECU explore to change VIN and sync DME_-CAS.
2: Check read out VINs type key. Use E-sys to change original FA's type key->save it.
3: Load modified FA to caculate swfl, cafd...and flash it.
BTW you must use replaced engine wire harness and all parts.
