One of my hobbies is being an amateur mechanic on my two classic cars. Both of them have a modern ECU installed. How does this link to hifi?
Well, one of the important parts of the ECU is grounding the shield of the cable that connects to the crank sensor to the ECU. If you don't ground the cable then you get huge amounts of interference in the signal and things go very wrong.
Has anyone done this or does this? Clearly grounding is important as anyone who hasn't grounded their turntable knows. In fact for the screening to work it would need to be connceted to something.
It would be quite easy for me to crimp a ring terminal on to some cable connected to the screen and use the grounding lug on the bottom of my Brio-R.
I am surprised it's not a big selling thing, for the cable companies it's surely a way to sell snake oil if nothing else.
