MSS54 / MSS54HP Tuner
Tune your MSS54 or MSS54HP without manually editing hex.
Load a supported DME binary, let the tuner identify it, choose the modifications you want, review the proposed changes, and generate a modified file through a clean, guided interface.
Detects supported MSS54 and MSS54HP binaries and displays key ECU, software, hardware, and flash information before changes are made.
Choose supported modifications from simple controls instead of manually finding offsets, values, and calibration locations.
See supported current and proposed values so you can review what the tuner is changing before generating the modified binary.
Supported checks can recognize when a modification is already present in the uploaded binary.
Select multiple supported changes and generate one modified binary instead of repeating the editing process for each feature.
Track the patching process with visible status messages, applied changes, and error feedback before downloading the result.
Integrate supported CSL-derived shift, rev-matching, calibration, and inertia parameters.
Retains the last Sport or Comfort setting across ignition cycles instead of resetting every time the car starts.
Select supported target-speed presets from a dropdown instead of manually editing the per-gear velocity table.
Configure supported stationary/dyno and in-gear RPM limits with straightforward selectable values.
Load Binary
Upload a supported 32KB MSS54 or 64KB MSS54HP BMWFlash partial read.
Identify ECU
The tuner analyzes the binary and displays detected DME information.
Select Changes
Choose the supported modifications and configuration values you want.
Generate Binary
Apply the selected changes and download the resulting modified file.
Start with a simple drag-and-drop or file-select workflow.
Supported tuning options are presented as clear feature cards.

Higher-risk and emissions-related functions are visually separated with additional notices and access controls.
Private Processing Workflow
Your binary is transmitted over HTTPS to a private processing server, patched, returned to you, and is not stored.
