Motorsport developments are one of the best tuners in the country. They are very big in the ford scene and have done some impressive work on bmw diesels. They are a very very reputable company and stu and kenny are top blokes. I have used them befor on all my cosworths and will probably get me 330d mapped there eventually.
 
Are Cosworth ECU's much similar to a modern Bosch ECU?

No doubt they have had some success in 'old stuff' but any monkey with a couple of grand these days can buy files off the web with a half reasonable tool & do "impressive work"
 
You are taking the piss right? They are a very reputable company and dont just tune cosworths they do a vast amount of other cars aswell. The reason i said they do impressive work for cosworths is because they do, they produced a wasted spark system along with closed loop fueling etc. What i'm getting at is they ARE a reputable company just cause you havent heard of them doesnt make them "any monkey with a couple of grand".

Anyway next time your in wh smiths pick up a copy of performance ford and have a read of 1 of his technical articles Stu writes for the magazine
 
I've written articles for magazines... doesn't mean that I am gospel though...

I don't believe that anyone can claim to be an expert across all fields of all vehicles.
