Studie Tuned Program BMW F30 320i Tuning ECU Purchased from a used parts shop, but ultimately never installed. Therefore, functionality has not been confirmed, and it is being sold as junk. I was told it was removed from a 320i M Sport, pre-facelift (H27). Detailed specifications are unknown. It is a set consisting of a main unit to be installed between the four sensor bypass cables and the ECU. The four cables are for: camshaft sensor, boost pressure sensor, air mass sensor, and manifold air pressure sensor. Please understand that the functionality has not been confirmed.
