Probably difficult to say as the Cossie map is probably not suited to a CVH at all.
Stu may however have a couple of base files from previously mapped Cossie managed CVH's he could send you.
I see what you are saying but what i thought was with the engine NOT being a 1.6CVH but instead 2.1ZVH the std cosworth fuel map would be closer to wanting to run the car due to the similar cubic capacity but i could be wrong?????
