Backup ECU BDM

[huntersub84]

I have a question that maybe ? gi? been made but not one I found on the forum

In parit? SW and HW, a backup BDM, can you? mount on any ecu to equal the SW and HW?
I translate better to the phrase twisted

If I programming the ECU of my 159 1.9 jtdm 150 hp, the block, and I have not done a backup in bdm, can I replace with one that has the same number of hw and sw, and then retrieve the ecu?
Or ? better to have a backup to keep in the store if ever you have problems?

Thanks for any answers

if you write a full backup to another unit with the same sw and hw need to do a scodifica part of the e2prom, because inside them there are the data immo, and then you have to riscrivergli also your injectors, then ? always better to do a backup before the ecu, so in the case of a block to throw in everything and you're set.

Very good, I have confirmed my doubt ;)

Thanks a lot

And if you happen not to be in possession of the file ori of the e2prom and micro (why? maybe you ? read by OBD), can you? write maybe another backup (e2eprom, micro and flash)? same car, same configuration engine but with HW and SW different..? (Of course, being turned scodificare partial key code)..?

but sorry, in the backup..a file would not have the same gold that you read through the OBD?

no eobd only read the part where there are maps, then if you write that file in the bdm, the machine is not part of the safe because it lacks all of the management, while if you write a file that is read in the bdm serial writes.
