saxo 1.1 ma3.1 0281204622 immo off eeprom

[vitorponte]

Hello guys, In my search for doing immo off on this ecu I am getting confused about the memory to work with.

In this ECU, a bosch MA3.1 0281204622 have 2 eeproms, B58221 (93c46) and B58390 (24c02 I supose).

In IUD and in the fórum some say to put FF in 24C02, or just remove eeprom, or change the content in 93c46 (put zero in first 6 bytes). also read from someone to change 93c46 with 24c02, wich are not interchangeable????

For who already worked with this ecu what is the real solution?

I did not read the eeproms yet so no bin attached, but I attached some board pictures.

Thanks

Vitor

HI
SOLUTION is:
memory 93cs46 write values 00 from 00 to 05
and cut off pin22 and 34 from ECU plug

That was my idea too, already cut the pins and conected ignition 12V (from pin 37) to pin 22 exit of the ecu so the engine light will be off without open the dash.

I will try that option first and check if work properly. Have to send the ecu from one Island to another and just wanted to check my options first.

Thanks for the help
