immo off on a opel corsa 1.3 mjtd marelli 6jo

Guys,I give a short explanation for the scodifica total of these ecu's that apparently are not as discounted as the other

unlike 6jf-6f3, etc. scodifica the total or partial is not feasible to bdm,flash, etc..
you therefore need to open the ecu with the pcb completely naked and then removing the under part,unsolder and then the 95320 present near the microprocessor, and read it with upa,then I will explain why

I process it with carprog,that is why I have inserted this brief guide in this section.

carprog is the only program I found that allowed you to do the total on this ecu
you have to choose the 4T version (there is also the 3T) in less than a selection of what you want to do,if it is not to try it with 3T but usually, the 4 is the one that goes well

once processed the file, write in the eprom
over the writing you have to write in the status register, the value 8C, which serves to make the eprom read-only so that the ecu does not write the new immo
the other programmers don't have this function
you could also raise the pins 3 door on the 4(so I have read, but no on was there I put my hand on fire)

replace all and you're done

The only problem is that the light will remain on

"you could raise the pins 3 door on the 4(so I have read, but no on was there I put my hand on fire)"
Yes, this we say is the procedure "traditional" not to rewrite the memory from the ecu itself, and then change the values of scodifica total (even if, according to me you wanted to write the pin 7-8). However, there are also sw that make the total on this ecu but will not work for all types of software of the ecu the same, and proceere soldering the two pins to make the memory read-only.
Anyway, thanks for the share, useful.

nono,I said just the 3 on the 4,because from the datasheet, it shows that the 3 is not connected, it blocks the write and the 4 is the mass

also sorry if I wrote carprog but I wanted to write carsoftware8quindi software,not hardware),which is semifree
