Afraid not mate, I've had to correct a few people mind!
I've never been into the Cosworth management tbh. Some people seem to get on with it pretty well though, and get good results. I suppose it's easily mapped ect. Certainly in comparison to EEC-IV. That said Moates can allow some mapping of the system.
EEC-IV in my opinion is a great way of gettin EFi on your Escort, plus gives you excellent future provisions for an aftermarket ECU.
