EZ Tuning: BMW Remapping

BMW Remapping

BMW engines are engineered to a very high standard but leave the factory detuned. BMW sells the same engine block in multiple power outputs across different model grades. A remap closes that gap.
EZ Tuning provides mobile BMW remapping across the West Midlands. We come to you and write a custom map for your specific vehicle.

Why Remap a BMW?

BMW maps the same engine differently across model variants to protect sales of higher-spec models. A 320d and a 330d often use the same engine block. The difference is largely in the software.

A BMW remap rewrites that software to deliver closer to the engine’s actual capability, giving you more power, better torque and in many cases improved fuel economy.
