What's the differences between Golf and Corrado cams?

hiya toyotec thanks for replying,, problem is this , i was givern a idenical ecu and obd1 loom set up as my friends, us ecu/emmprom chip/ which works fine on is vr6t set up , yet dosent idiol fine on mine , reason why im not 100 percenert sure , other then his maf length is a lot longer then mine , other then this its idenical ,, regards rest we have the the same set up , ive only found out today(that my ecu hasnt had a costant live which i think has been causeing issuies, not to saveing ecu adaptive settings , and starting from scratch,
as ive changed the wire pin 54 if i remember right(red/yellow) to constant live , instead of switched live yet engines still reving very high on start up , and very steady drops to 720rpm ,, which i recomend isnt good for the engine ,[:^(]
