well I had to study again. Now I have MPPS working on a virtual machine on win 10. I was able to connect to the ECU and download the bin file. Now my understanding is that I can directly connecyt to the car and transmit the new map.
My intention is to send the map I received in this thread.
Is there any precaution or safety procedure I have to observe to avoid any damage?

because of covid19 I am forced to stay home so I got time for tuning.
I got a spare ECU and I was able to flash the 5P08C3 chip with my own ECU to have it work with my car.
Then I started flashing the map.
I am working with MPPS on a winvare machine I was able to read the ECU and flash with the file given in this thread.
The car starts and runs very good, torque increase is very good.
I only have one minor issue that I am trying to fix.
Apparently the checksum is somehow conflicting and I have the red engine warning light on. I can delete the error with MES but when I stop the car and start again the warning light shows up again.
In the process of flashing, MPPS is asking to verify checksum before writing but it is not very clear how to verify/fix checksum with MPPS.
I wonder if MPPS MUST be the same for both file or not.
I hope I was clear and kindly ask advice how to solve the issue.
Is it dangerous to drive with red linght warning...I do not think so.
