Made up 4 wires. Had some trouble with the existing one going from the battery to the gearbox... Didn't know it was split and attached to the frame. Haha. Pulled like hell until I found it bolted tight.

Well. The car starts pronto now, and revs up quickly with no hesitation.

But what is most noticeable is that the amp in the boot produces much more bass! Something is giving the good old Phoenix Gold much more power - and it's most likely the new chassis ground right besides the battery box. See pics below:

It was minus 8C (not the Alfa) this morning. When I turned they key in the ignition the starter engine nearly engaged. It just started. Maybe within 0.5 seconds. 77Ah Varta combined with new earths was a very good investment.

Bumping a really old, but useful thread

I've been running my new ECU without a ground wire for about a year, since I moved it to the battery case (Stilo 1.6). No problems whatsoever.

The mechanic said it doesn't need any grounding. Is this true ? What could go wrong ?

When I tried to undo the nuts on the negative terminal they wouldn't move, even with a half inch drive ratchet and socket. I was in danger of bending the whole unit so I just gave up. Has anyone else had this problem with the nuts in the last but one picture in Stilatos' post.?

Yes I had the same problem Jim. I was lucky to get one of the nuts to shift and ended up putting all the extra earth leads on one post.

Nothing much - but very much talk in a language that Google translate cannot translate to any sense.
