Hello! I have a few questions to experts. I have ECU Siemens S101722101g. I downloaded the firmware from TMS27PC256-20NT.
In IMMO Universal Decoding 3.2 tool there is solution for S101729103h. It says:
1) Cut the pin 29 on Motorolla MCU68HCP11E
2) Save the file
3) Unzip the file
4) Program an empty EEPROM 27C256 with this file
5) Replace original EEPROM with new EEPROM
6) Turn the ignition on 30 seconds
7) Replace new EEPROM with original

BUT my chips:
MC68HCP11E1VFN against MCU68HCP11E in solution
and
TMS27PC256-20NT against 27C256

Does this method work in my case?
Thanx!

Just Read MC68HCP11E1VFN and Fill all lines FF FF ... except last two lines
then Cut immo line 29

Should I fulfill paragraphs 6) & 7) from solution?
Thank you!

This is Fenix 3 ( 35 pin connector ), you can do it very simple with Reno immo tool, 1 h 50 mins waiting the tool to do its job, you can have a coffee while waiting.
Nothing to desolder, only connect a couple wires to the tool that`s all you have to do.
