Remember theres no such thing as a difference between the one and cooper. The intake, head, internals, manifold etc are all the same. The only real difference is the map. The cooper map will work fine on a ONE. However if it had of been me I would not believe that its a genuine BMW map .. These companies like to keep thier products close so I would say its more likely to be aftermarket one which is being sold as genuine BMW.
I'd have bought AMD, Bluefin or MTH personally. However good luck to you |
