I have transferred over to a megasquirt ECU on my project so the original cossie one is up for sale. It's a 1GAA code by the looks of things, it worked fine in the Cossie Granada before removal, and I'm pretty sure it was used ok at one point on the project, but it hasn't been ran in anger as it were for a good 2 or 3 years. So would class it as 'used, presumed working ok'.
Images below for your perusal:



Open to offers on this one, most I've seen available are in the £100-150 range in various states of condition. So I'd say offers around the £100 Mark.
Postage can be arranged, but depending on cost the price might be + P&P.
