Tuning firm Hartge has released their engine conversion (additional ECU) for 118d, 120d, 318d, 320d, 520d and X3 2.0d. Today's high-performance engines, many of which have already been almost fully developed at the factory, call for tuners who can do more than just tweak them digitally.

Indeed, chiptuning is a magic word in this age. All Hartge engine components and chiptuning are tested on the bench and on the road before being approved for sale.

Hartge experience goes back for 36 years in the field of high-performance engine building. All Hartge tuning components are supplied with TUV approval.
