For magneti-marelli ECU you need to unsold the eprom 29F512 and resold a support for eprom. after you have to place a specific eprom that could be buy in ebay look at this link IMMO OFF DEVEROUILLAGE ECU IAW 1AP.XX PEUGEOT CITROEN en vente sur eBay.fr (fin le 15-sept.-10 22:20:40 Paris) (http://cgi.ebay.fr/IMMO-OFF-DEVEROUILLAGE-ECU-IAW-1AP-XX-PEUGEOT-CITROEN-/230522371966). When you install this eprom , put contact on your car during 50 second , remove you contact and re-install your original eprom. I have bought this special eprom as soon as i will received it i could read it on send on this forum the program if it could help you.

good week end

And remember you can cut PIN48 of ECU connector, this way immo will not lock ECU anymore.

Thank you all.
I'll get to work.

Hello friends.
We continue with the mess ...
I have my new progrmador (willem eprom program) to work with the 28f512. I understand what you say PATMALL2 ...
But what I have to file the 28f512 program to begin the process and finally put back the original?
Thanks for the support.

Recommend the program to all works fine.

After the project be stationary several months, finally solved the problem of immo. I did as you advised me. I was very useful aid.
To avoid the soldering and desoldering MCU, I put a socket and is a good job.

Thanks

Step by step Instructions for everyone who needs it

1. You have to desolder 28F512 chip.
2. You have to erase 28f512 and flash the clock file I attach you and power on ecu on the bench or on the car for 2 minutes, whatever you prefer.
3. You have to erase chip and flash again your original file.
4. You have to CUT 27 and 48 pins.


Your car will start like a charm and never lock again, no need to remove immobox.
