What does the computer do? what is it for? do you need one fitted?

 

Doesn't come with one standard and can't see why you'd want one to be honest

 

It basically beeps a lot and makes out you are driving uneconomically.

Not fitted as standard and certainly not necessary. Although I have one I'm fitting to my cabby.

optional extra, not hard to fit but you will disconnect it sharpish is you dont keep you tank full

 

Had one on my second, H reg rst, thought the very late Escorts has them std, to get rid of, as they wernt used on the mk5?
Think, from memory, I 'turned down' my beep with a bit of tape over the speaker hole bit on the back?
