how easy to block an ecu read to tour?? what should I be careful?

[Alecsx]

of course, it depends on the track ? interrupted, if ? one of those that d? access to the flash ? normal not the read/ write

I mean that the bdm does the reading, but then when I open something is missing. you should not read when it breaks down? or if not interested in reading does not work, but will be able to read? I don't know if I was clear

you can know what is missing when you open the box, put the readings that you have done in the BDM.

eye open these because they are very fragile, it can happen that you ruin the pcb, the edc16 to be compared are rubustissime.

I confirm they are very fragile to me unfortunately ? happened crack 1 I by mistake P2146 - Voltage Capacitor Present
electrical failure;C. C. to ground according to you ? repairable?

try to ripassargli all the welds of the pins of the comb on the pcb, sometimes you crepano them and if you have any luck with the resume.

the micro is ok but the flash is missing something because it is the power

[ugoboss]

I only have a file that is read in serial with only the tables, which are equal to yours, you should find a file full bed in the bdm to be able to reconstruct what is missing.

Thanks Ugoboss but I came out of it . I replaced the ecu with a compatible the same hw but sw is different . copied to the micro
fortunately, he was well-read, and then went in the saab and I have reloaded everything that was lacking. jinx wants that I didn't have time to read it.
as soon as I can I'm curious to see what the missing part that would not let me start the engine.

then you have broken the ecu, or you have screwed up with the readings of the flash I did not understand.....

[Alecsx]

I've broken the ecu by opening it , and also to replace it I had a flash of a healthy why? not read full.

in any case, do not throw it away, a friend recently had a similar problem and has found it is adjusted.
