hello,
I would like to share my first experience of a backup in the bdm with the Cock, V2 clone (V51) and related schedule.

The unit in question ? a Marelli NEVERTHELESS+ a Meriva 1.3 cdti 75 hp (3124M149).

I have collected a lot of information on this forum and who sold me the cock, and cos? I have proceeded.

1) food without the rooster, I connected from the skein of the serial of the cock, the pin 5,6,23,50 +12v and pin 1 (GND). The green wire from 88-Kline, I have connected (as I had seen in a few pictures on the ecu Marelli).
2) I used the schedule provided with the Cock, to which I first had to solder the connectors provided. Must be welded so that the chevrons printed on each connector to correspond to the respective printed on the schedule. This serves to allow the correct "layout" of the pin from the rooster to the ecu.
3) not having the schedule in the spring, I have "thrown" welding of the flat connectors, 6+6-pin bdm port of the ecu. This is because? I was sure I was not caught at the first blow, the right link to the e xxx. With these male/female connectors I could easily change the connection without solder and desolder the ir? times (risking damage):
4) to read this Marelli me ? been suggested (something that, in my opinion, it was not clear from the manual of the rooster) interposing the e xxx CMD between the Cock and the e xxx Marelli, then:
GALLO -------E XXX CMD --------E XXX MARELLI ECU -------
5) now to be found on the PIN1 on the ECU, as clear instructions on the manual of the cock. On my ECU, the 6+6 pin bdm port, the PIN1 ? turned out to be the pi? away from the hole in the lid, and then looking at the ecu with the connector at the top, the pin in the upper right.
6) unsoldered the resistor 0 ohm as in the manual (eye on the type of the ecu though ? NEVERTHELESS or NEVERTHELESS+, the resistance to remove ? different)
7) any user who does not remember he reassured me saying that I could also be wrong to connect the pin of reading between e xxx and port bdm that nothing would happen (the important thing, according to him, was not to mistake the power supply connection to the comb). Then I tried to connect:
- making to fit the pin1 output from the e xxx Marelli (small arrow) with the pin1 ecu ---> no reading
- making to fit the pin1 output from the e xxx Marelli (small arrow) with the pin12 ecu ---> in this way, the GND of the Rooster (pin5) corresponds to the GND of the ecu (pin3) ---> read OK

Before reading it I noticed an error... to the comb, I connected to the pin 50 is not the red cable but the cable orange (not to be confused). Also this is the ecu for me has forgiven you... not bad, not bad...

I hope you can understand how I have connected the various schedule in this photo.







Not ? said that with the other ecu, the thing is the same... I hope this post is useful to those who are close to the reading of the bdm for the first time.
The file reading bdm complete (micro, eeprom, flask-all) I have them uploaded in the database of the forum.
If I wrote a few boiata, please correct me!
hello!!!
