ECU - Can you look 'inside' it?

[manxseven]

Hi Guys,

I have a spare Williams ECU with a Prima Racing stcker on it :!:

I would like to now if it is any good and what if anythning is different over a standard ECU.

Car is not running at present, so can't swap it over and drive it to see if any difference.

Can you plug it into anything (Laptop??) to see ?????

Cheers,

Simon.

Undo the four screws and look inside the casing. You'll probably find it has a chip fitted inside.
