Fiat Idea 1.3 JTD BCM SWAP

Hi to all!
I have an fiat idea 1.3, year 2004 with a burned BCM. I've found a second one with same part number, extracted code and programmed 2 transponders. Puted on car and virginized ECU with FVDI. After weaiting 2 minutes and switched ignition on, the pin code from ECU remained the same and the card did not start. I have electronic key DTC. Guessing it does not recognize the key.
I've connected the old BCM with car and also did not start (before ECU was virginized with FVDI the car started, the BCM was burned on STOP LAMPS commands), same DTC ''electronic key''. I don't understand why the ECU does not sync with BCM after I make it virgin.
ECU is MJD 6JF.M1

Any adwice will be helpful, how to make this car start again, with scrap BCM.

P.S: I've attached the scrap and original BCM file (UPA read) and the orginal an virgin file from ECU (FVDI read).

why you did not make full clone of bcm before?

Because i don"t have xprog to copy flash.

maybe someone will sync for you but this job should be done by obd

What device to use to sync by OBD?
If it's virgin does not sync by itself?

Soo... is there any solution to this?

Can somebody make virgin the eeprom file from ECU 6jf.m1?
Original file attached. I read it with FVDI.

After tring IMMO Off in flash with FVDI the car still does not start.
Programmed new transponders in BSI...but still can't get the car start.
I've writted the original EEPROM file in ECU....when I first read the pin code show's correct PIN code 24338 but the car does not start, even with original BSI/ BCM. After I switch the ignition and back ON the code from ECU changes in 77777 and have next DTC:
On ECU i have "U1600- immobilizer: wrong transponder key" and in BCM still "U1600 - immobilizer implausible signal".
I don't have any other idea how to make this car start.
I've attached flash file from ECU (read with FVDI), maybe someone can make IMMO OFF on it.
Thanks!
