Problem IMMO OFF DCU3R DACIA 1.9D

[Dacha]

I did of the immo ecu DCU3R at the direction that I directed the forum.I enrolled for immo dump of the eeprom 95080, I activated the software write protect!Pin 3 eeprom I raised and tied to pin 4.

I cut pin20 on ECU but the car does not start.I found that a diagnosis is locked ecu because the status is still lights as seen in picture.

I attach the dump that I enrolled in the eeprom and please someone help with problem solving.

Put here your original dump, i`ll do it virgin for you, put it back and solder as the factory did - no more innovations with pins raised up ! - and USE EMU ! This is the only solution i found for D1304 Delphy DCU3R .
No work without 95080 in the ECU, no work immo off, only virgin and learn new keys or EMU.

tested before..

tested before..

Yea, tested by me too, m8 ! On old models of DCU3R worked ( older software ) but the newer software in DCU3R used in Dacia 1304 never worked.
Flash virgin and EMU = 2 hours work including making an emu by yourself, car gone ...

could you post the schematics of an ECU, please alfabit ? Regarding the other post, with the broken 95080, I sorted that out, got another ecu from the scrap yard with key and everything.Thanks for your help!

Later edit : schematics of an EMULATOR I ment :)

...schematics of an EMULATOR I ment :)

No problem, taken from DK, given back to DK !

Both work the same, you make the one you like.
Personally i advise you to make the Atmel version, very reliable and cheaper than PIC version.

Thank you very much for your help!I'll try with removed eepromom even if it is not going to do the engine started emulator.Can anyone here to ask for the PIN OUT for ECU connection out of the vehicle to be able to connect it to the workshop and check if immo off successfully without any installation on the vehicle.

Can you send me the virgin dump for my ecu?

DCU3R 8200126607 HOM 8 200 131 940

214208 FVG
80909B

After writing virgin eeprom to dump if you need to return to the eprom ECU like the factory-installed without any modifications?

[Dacha]

The only true solution and the emu and the virgin dump!
