Hartge Engine Performance Upgrade – F30 328i, E89 Z4 28i, F10 528i 12-, F25 X3 28i (N20 Engine)

Hartge releases their new engine performance upgrade for the F30 328i, E89 Z4 28i, F10 528i 12-, F25 X3 28i (N20 Engine). The package ensures a 45 hp gain and a torque increase of 48 ft-lbs.

The Hartge ‘Engine Conversion’ is a bespoke tuning module that plugs in ahead of the engine computer on the wiring harness. It has factory-style plugs to connect in-line with the water temp sensor, fuel rail pressure, turbo boost pressure sensors, turbo wastegate valve, intake camshaft sensor, 12V power and ground. The module then sends a modified signal to the engine computer allowing it to increase boost by varying amounts depending on load, engine speed, and other factors.

All of the factory safeguards remain in place, including overload protection, warm-up protocols, and the engine tuning is unchanged below 70% throttle to preserve all factory driveability and emissions certification*. One of the key advantages of this type of ‘piggyback’ system is that it is unaffected by factory BMW updates and service. If BMW updates the computer software to fix any small bugs or issues, the Hartge performance upgrade is not lost or overwritten. This is key on a new model like the F30 because BMW is constantly releasing small software updates. All of the factory diagnostics and service access is retained.
