BMW 330d Stage 1 Remap

Big six-cylinder pull in a compact 3 Series. The G20 330d is quick out of the box, and a custom map gives it the kind of mid-range shove you’d expect from a much bigger car.

How a remapped 330d drives

+100–135Nm

Small car, big pull

In a car the size of a 3 Series, 720–755Nm is a lot. It pulls from low revs like a much bigger car, and overtakes that used to need a long gap now just need a look.

+65bhp

The long commute

At motorway speed the 330d sits in eighth gear doing very little. Remapped, a squeeze of the throttle is often enough to gather pace without a kick-down.

Touring, fully packed

Loaded for a holiday, the 330d Touring keeps its pace on long inclines instead of kicking down and revving.

The G20 / G21

About the G20 / G21 330d

The 330d is the six-cylinder diesel of the G20 3 Series, offered as a saloon and a Touring. It’s a compact car with a big engine, so the extra torque from a map makes it feel properly quick, and it’s a favourite with high-mileage drivers, who feel the stronger mid-range every day.

Is the G20 330d a B57 or an N57?
