Will do that, however: even the original bin did not work. Tried three bins which ran successfully before this trouble started.

Alrighty!

After a visit in my local hardware store and a couple of hours soldering and testing, I can flash the ECU on the bench using a Galletto cable.
I now officially declare this ECU UNBRICKED.

However, the engine still won't start, and I cannot connect using the NEfmoto software once I connect the ECU in the car (quick and dirty - just the inner ECU case and the two main connectors.)
Something I do miss, hmmm...

So what did I do?
1) Boot mode (pin 24 to ground through 6k) - check
2) Galetto <ECU DATA> .... result "ECU number not found"
3) <Open file>
4) Select bin (my last working one)
5) <Download file>
6) 1 ... 100%
7) Unclear Italian comments that I should switch off the ignition for 10 seconds, ok I did that
Galetto closes the ECU and declares it is happy.
9) Shut down the 12V supply
10) Disconnect all crocs
11) Run to the car with a phony smile on my face
12) Connect ECU
13) Turn ignition key and try to start.
14) Engine turns, no start.
15) Clench fist, remove ECU and back to bench.

I remember reading something about problems with flash but no start somewhere.

Back to googling the forum...
