Hi to all guys accept advice on how to repair this blessed unit which is subject by the cursed problem when you turn the engine on 3 cylinders. Someone of you has already? performed this type of surgery?
Thank you in advance
Daniele.

I should have some photos of a m3 with the repair made, to? I don't know if the rules and regulations are authorized, even the first time I opened one I damaged in a hurry why? I drilled the rivets.
you can? repair and restore the "track" but did not ? said that you will be successful
to know the track damaged as dev proceed?
in fact, if you take one in the belly is the best!!
You do not really understand something until you can explain it to your grandmother (Einstein)
listen to the advice of motorsport now those ecu will find them a little
open it do na photos and e-mail. if the track and healthy, the repair should be done by the other party. that nn if you have expertise better to let it go.
the best way is that (as you said) to take a to collapse and scodificarla
Unfortunately, repaired last just a little even sometimes give problems even those revised,better to opt for the breaking of trust
those ECU have a fault in the handling of the coils, the circuit ? under sized compared to the absorption required by the ignition ? it often skips the track of the PCB that the pi loop? weak... other times, especially if it concerns the hardware changed of the series (with bridge reinforcement) in this case, often part of the power transistor. it is a Mosfet N-channel... in any case you can? check the integrity? with a multimeter once you have disassembled the ECU. in the meantime, the council pi? trivial that I can give ? to check the continuity? between source and GND (center wire mosfet). if isolated redo the track ? that burned it.. to do it again, you need to have welder suitable, temperature-controlled, works with temperature not higher than 300?, I recommend you must have very steady hand and quickness? in the run! if you overheat, deteriorate and burn the track irreparably damaged then you have to throw the ecu. I time ago I also replaced the modules, putting the power mosfet with the container To220 outside, to the other a termination clause in that the current of the source-drain ? better dissipated with the transistor plus :-)
