RS DIAGNOSTICS / BMW DIESEL BUILDS

BMW diesel tuning projects

Engine, turbo, fuel system and transmission configurations from three RS Diagnostics BMW diesel projects. Each profile brings together the build specification, photographs and the available performance results.

Performance results and their sources

The 135xd profile includes owner-supplied Dragy screenshots and run conditions. The E91 335d figures come from an HCR Dyno post dated 21 May 2021. The 135d 1M replica figures are attributed to the vehicle listing. These sources describe individual builds and are kept with each project.

RS Diagnostics projects and the RSDiag app

RS Diagnostics is credited for the tuning work presented in these project profiles. RSDiag is the BMW diagnostics, Live-data and ECU calibration application presented on this website. The project pages document the vehicle builds; the app’s supported functions and compatibility are described on the features and documentation pages.
