## Description

This Chrome extension, MHD N55 E-Series Utilities, is being retired. Please switch to the unified MHD Flasher app, which now supports all E/F/G-series vehicles and Supra. The old app will remain installed as a shell to aid the migration and preserve access to essential functions during transition.

The shell keeps core capabilities: reading and clearing engine DTC error codes, graphing and analyzing prior datalogs, viewing existing vehicle licenses, and accessing the user guide.
