How to Flash Chevrolet Cruze Simtec 76 ECU with Kess V2

Today I was flashing the engine control unit on the Chevrolet Cruze A J300 2012Y 1.8L AT.
The car arrived with errors after the service, where they changed the rear lambda, put a trick, checked the wiring, cut the cat, etc:
kess-v2-chevrolet-cruze-catalyst-control-1
The owner of the car is already tired of all this, so it was decided to flash the calibration under E2.
What I actually did)) Siemens Simtec 76.1 control unit :
kess-v2-chevrolet-cruze-catalyst-control-2
For the firmware, we will use the KESS V2 Master V4.036 programmer :

kess-v2-master
Go.
Launch KSuite :
kess-v2-chevrolet-cruze-catalyst-control-3
Select the Chevrolet Cruze with the specified control unit:
kess-v2-chevrolet-cruze-catalyst-control-4
We fall into this menu:
kess-v2-chevrolet-cruze-catalyst-control-5
To begin, let’s make the identification of the ecu, choose the ID :
kess-v2-chevrolet-cruze-catalyst-control-6
Kess v2 displays ecu information
kess-v2-chevrolet-cruze-catalyst-control-7
HW: 10123891AM
SW: CAO95B20.DAT
VIN nr .:
SW ver .:
Spare: 25182010
Engine: F1G3
HW Ver .: SIMTEC76
SW upg .: J8IB20A4.DR
Installation:
Now we will read the ecu, select READING :
kess-v2-chevrolet-cruze-catalyst-control-8
In this case, the ecu is read ~ 5min, its correct size is 1Mb, it contains caliber. Send the file for calibration, or buy the edited firmware file. Next we will record, choose WRITING :
kess-v2-chevrolet-cruze-catalyst-control-9
Then select the desired file:
kess-v2-chevrolet-cruze-catalyst-control-10
We write the edited calibers:
kess-v2-chevrolet-cruze-catalyst-control-11
Recording takes about 1min. Now we will remove errors that could appear during the recording process, choose TOOL :
kess-v2-chevrolet-cruze-catalyst-control-12
In the new submenu, press DEL ERRORS :
kess-v2-chevrolet-cruze-catalyst-control-13
We agree with all that the system offers us. We see that the task is successfully completed:
kess-v2-chevrolet-cruze-catalyst-control-14
We start the car, we do not observe extra errors on the back lambda, that’s good.
All good.
