Do you know how these engines are different? Its the same ecu on both cars, 318i has 129hp, 320i has 150hp - BMW uses the same ecu on both engines as both are N46b20 2.0 litre engines. Same bore, same stroke, same everything on paper.

Is it possible to reflash the ecu with 320i map? And maybe tune the 150hp file for more power ?
