Default High comp NA Zetec, how to calculate CR

Hi all,

Im using a 1.8 zetec head which is not skimmed, 2ltr block with standard pistons and a standard 2ltr motorcraft head gasket and weber alpha 45mm throttle bodies. the engine is built and running in the car! Problem is, its over fueling on a standard 2.0ltr map which im told is going to happen due to higher the C Ratio.

Does any one have the volumes of these to hand or know where i could get them from.

Thanks in advance.

John T
