I've just installed a set of electrical grounding wires in my focus
sedan today after being 'sold' that it would improve performance among
other advantages like minimizing interference to audio equipment.
It is basically connecting thicker copper grounding wires to parts of
the engine, components and chassis directly to the battery terminal.
Theoratically it should improve response as it improves electric
supply to the ECU.
So far I've driven it for about half an hour and did not find any
...maybe it's a case of sounds good in theory but don't work so well
in practice...? :p
I'm wondering if anyone has tried this mod and found that it helped?
