bmw engine swapped

[jordiksvk]

hello folks
me have bmw e90
original was msd81.2 ecu and 1.6L engine
engine dead, and instad mounted 2.0L motor
car works but on iddle it have bad RPM


ecu from 2.0L i have but with this ecu car not starting.
ecu from 2.0L is MSD80.2


please could smbdy match this ecu to car ?
ISN from 1.6 is need put to 2.0L ecu ?
then coding injectors?
and vin coding?


thanx for help

Read isn from ecu (2l) and wrote into CAS. Also change powerclass ...
Then VIN and Injector...

[jordiksvk]

is not possible change ISN in ecu ?
isn from dump is not possible ?
i dont known ho to read isn.....
me thinked isn is in flash on 0x1100 position 16bytes....
chks was corrected by flasher.....

me tryed paste ISN from 1.6 to 20L ecu but seems not success...
in dump attached,
on diag: anti tamper protection in engine ecu error
starter working (cranking), but not started run engine

also vehicle vin is:
WBAUE31080E180086 (needed)
and 2.0L ecu vin is:
WBAWK72000PX06450

car have only engine swapped 1.6 to 2.0L and driving, but bad,
need to put there ecu coresponding to 2.0L engine
Thanx


isn 1.6: B4FAA976B04222A3BC9B9FD33C18F1D8 ???????? dont known if ok
isn 2.0: 7A0167D6D24C7A7F4E22C7668F1E8255 ???????? dont known if ok

ISN Adress in ecu is right... rest is writte before.

can be fixed , pmed you
and can change isn in ecu

i have readed cas3, its from original car1.6
how to pair it?
thanx

flash from cas3

Hi Jordiksvk.
Maybe it's better to try to make a new flash in the ecu with Inpa or Ista. Then synchronize dme with cas.

Try it...........

Hello
after adapt cas3 to new ecu
still injector 1 and injector 4 missing ignition
and lamda sonda before catalisator
injectors was coded.....
lamda is new and the same.....

on original not have any problem....
bad reaction for fuel pedal.
