## Description

This extension is being retired. Please switch to the unified MHD Flasher app, which now supports all E/F/G series vehicles as well as Supra. The N54 app will remain as a shell to help you switch over.

Additionally, some functionality will remain to read and clear engine DTC error codes, graph and analyze your prior datalogs, view your existing vehicle licenses, and access the user guide!

## Review summary

Users praise MHD Flasher N54 for ease of use, phone-based flashing, data logging, and a rich tune library. However, recurring issues include licensing disruptions after updates, reliability problems with flashes and idle/misfire regressions, and logging/connectivity bugs, plus mixed support experiences. A notable limitation is the inability to monitor while the engine is running. Overall, the app is valued for its capabilities, but stability and licensing workflow concerns are the most mentioned negatives.

### Pros

- Easy to use and straightforward interface.
- Allows flashing the DME through a smartphone for convenience.
- Data logging feature helps diagnose issues and monitor performance.
- Extensive tune library and quick tune switching.
- Generally positive perceptions of customer service and license-related refunds/assistance.

### Cons

- Licensing issues after updates: licenses disappearing, license transfers failing, and long wait times for licensing (e.g., 24 hours).
- Reliability problems after updates: failed flashes, idle/misfire regressions, and performance drops in some maps.
- Logging and connectivity bugs: live logging freezing, write failures, and WiFi/iOS connection problems.
- Mixed or slow/unhelpful support responses for licensing and account issues.
- Feature limitations: cannot monitor while the engine is running and other related workflow limitations.
