MHD Flasher N543.21 - App Store

This app is being retired. Please switch to our unified "MHD Flasher" app which now supports all E/F/G series vehicles / engines as well as Supra.

This 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!

All previous requirements remain: you must own the pump gas map pack, ethanol map pack, and FF license (or super license), and flash a V8 or higher pump gas (not ethanol) map, but now also with the flash option checked. This flash option checkbox will only be visible if you own the correct licenses and are flashing the correct OTS map.
