BMW E61 535d — turbo diagnostics and power calibration

ECU calibration, diagnostics and dyno testing for a twin-turbo BMW E61 535d.

ECU remapping twin-turbo diesel dyno testing diagnostics
Date 11.12.2020
Vehicle BMW E61 535d
Year 2006
Engine 3.0 diesel twin-turbo
ECU EDC16C35

This 2006 BMW E61 535d has a 3.0-litre diesel engine, twin turbos and an EDC16C35 control unit. After the turbos and engine had been repaired, the car no longer delivered the response the owner wanted. The ECU software was reviewed and diagnostics were carried out before calibration.

After the software was revised, the dyno recorded 376 hp and 728 Nm. Engine data was also checked before and after remapping, including boost pressure and fuel-system parameters. At the end of the video, the technician describes these readings as operating correctly.

In this case, the software changes followed diagnostics and testing rather than relying only on the previous file's power figures. The stated final result is the dyno measurement after the new calibration.
