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 new models because BMW is constantly releasing small software updates. All of the factory diagnostics and service access is retained.

Hartge Engine Conversion 362hp/480nm More Boost With Factory Driveability! This Power Pack is a direct plug in to the existing engine harness for a factory appearance and fitment and an instant 56hp gain. 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 1500 rpm to preserve all factory driveability.
