problem BDM or simple bad luck ?

[Mr.Flash]

hi guys things have happened surreal ...

ecu marelli classic 1.3 mjet ...... one of the many made in the bdm , always with the usual bdm , with all the care of the case , etc ...... read, edited, written , ok for 2 days and then the car does not start more. Ecu went, the lack of communication, I associate myself with the BDM .... no recognition of the microprocessor. Dead.

these things happen, I say to you , even if inexplicable.... bad luck? or maybe a case. The Vab? , we didn't think much of it, we take another ecu, in the full backup, and on and on .

after a few months .......

ecu edc16c34 ....... read, edited, written ........... ok for 2 days ..... and the car is not the most!!!!! Here, too, the absence of communication, etc, etc ...........

Now ....... since I do not believe too much in the bad luck ........... what do you think ???

It's absurd , inexplicable ... provided that there is a problem with the BDM why? you ? wasted (doing his excellent work since 2007 without missing a beat!!!!) or in his alimentatorino...... or a problem with the welder..... or with the pc........ I can't explain how does the micro to be damaged AFTER a certain period of time and not IMMEDIATELY..................

ideas????


thanks

have you sealed the ecu after that ? been open?

never happened in a similar case to be able to give an explanation, if not the error of opening and closing of the ecu,
and/or actions of others on the above-mentioned ecu after your surgery...

[sno74]

Also I think the problem with opening the ecu and the sealing once written that the car part you are ok if after a week not to be, or has someone hacked or the pcb ruined that with the jolts of the road has finished break....

[giordano_mecc]

certainly that ? what a bizarre, strange, never happened to me????? I would change both the bdm that the power supply you never know!!

[Mr.Flash]

hi alpha! I exclude problems in the opening in the marelli but especially in the bosch ...... after so many openings, which became familiar to the point that I don't leave even signs of screwdrivers (I have built a sort of wedge appropriate) , clearly warm it just enough (not too much, keep them with bare hands, and therefore well away from the critical temperatures of the welds internal)

both ecu's have been sealed.

sno74: I I had come to think of metal shavings that were in and went to do a few short films with the movement of the macchina........... but I feel that you also exclude this why? last I have also blown with compressed air dry, cos? for care and safety. in any case, whit by, as I have seen on other ecu , open ones by me do not have chips.

c'? consider that between one and the other the BDM ? been used for other ecu also of the same type....... and ? always everything went well.

? a really ugly as I do NOT UNDERSTAND what happens.............and there? I do not like for nothing !

[chiptuning.cro]

are you sure that is not the warm up too much, you may be the one...
to me it's never happened, but I senttito by colleagues that it is possible to...

[alfajtd]

if you have warmed up too much or in the wrong way and/or on some component gi? defective may feel a dissaldamento of some component that is now up and does not touch....

[Mr.Flash]

as I wrote above, hold it with bare hands...... how ? can unsolder a component with temperatures in the cos? low? I don't think it is possible...

then I open hundreds , I'm sure that the problem is not ? due to the aperture, or other............ I had thought of some problem in the BDM or power supply I would ask you if you have never heard anything like it.... ?

[ugoboss]

and happened with the power supplies, the chinese, who gave less voltage but is not connected even to the ecu, if instead gave more volts I know that jumped immediately, I am inclined myself to think of a problem of the opening, because it's not the first time that people who are open to tens happens a few problems.

[sportknight]

I once by mistake I powered up to 17 volts, but the ecu still works....
