VAG SIMOS PCR2.1 WRITING ERROR WITH KESS

[Francisco1970]

Hello friends, I have a problem with this ECU, I wrote the file with Kess by Full OBD II (new family) protocol. The original file was downloaded automatically when I identified the control unit, I eliminated the DPF and EGR, and started writing, everything went well until at the end of writing a window appeared indicating that there had been a writing error.
I tried to write the file again in recovery mode, but Kess is not communicating with the ECU. What can I do to repair that fault?
I don't know if the problem is in Micro memory or Eeprom memory.
I have disassembled the EÇU from the car and have been able to read those memories with Ktag in Service Mode.
I attach the files that I have read.
I would really appreciate your help.

Hi. The first and fundamental question. Did you unlock the ecu with the Kess on the table? And what Kess do you have? Ori or a clone?

Hello with the new function of kess OBD II new family. When you write the file, it is not necessary to unlock the ECU (possibly kess does it automatically when it writes). I had already written more than 10 Simos pcr2.1 ECUs this way and had never had any problems. My tool is a
Kess is a clone (Russian with virtual reader included).
I have original ktag with which I have been able to read the Micro and eeprom memory, but those files must be wrong, that is why I cannot write by obd and the car does not start.

Well, Chinese clons have it. Sometimes it can't unlock it properly and it crashes. This feature only works properly in ori kess. And do you connect with the Ecu tester? Try Ktag to do two readings and compare if they are identical.

I guess the Russian clone has higher quality electronic components than the Chinese clone. So far it has worked perfectly for me.
I already made a comparison of the files, but the file that I wrote in the ECU, had modified the egr and fap maps, I have cut and pasted the cartography of the original map ( downloaded from the alientech database ) in the map that I have read with ktag, I need to test it in the car . When I try it, I will tell you if the car starts.

Hello dear friend


I don't think the russians bother to make the PCB from a to z, they play with the software that they managed to crack and keep it secret to earn money, if you send the pictures of the PCB to russia we could confirm it to you, concerning the Kess V2 tool Had the best options remains the Carprog site with its purple pcb. Good Job.
