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

[baraldino]

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.

in fact, I noticed it,st? studying a tool :
a part that allows me to block in tranquility? the ecu in a move through the holes.
and a part type extractors that puts to pull the cover and not v? to touch the card, so I avoid any streaks with the screwdriver in an attempt to lift the cover,

I am sure that is also heated to a duty sealant,for the strength that must be put to open these ecu, sooner or later, a shot of the screwdriver gets me in trouble.

[ugoboss]

you have to try to block the comb of the control unit, together with the fund, so that when you make a lever to remove the cover efforts on the welds on the pcb.

I just opened another edc16 of an opel astra, I feel safe, but tomorrow that I try and find out if I have learned from my mistakes.

[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.
