MHD Super License for S58 Engine - including BMW M2, M3, M4, X3M, X4M (G87, G80, G82, F97, F98 Chassis)

Overview

The MHD Flasher F+G Series is a complete flash-tuning app for the S58-powered BMW M2, M3, M4, X3M, and X4M. Unlike a piggyback module, it performs full DME remapping while keeping every OEM safety system active — delivering real power gains without sacrificing daily-driver reliability. This Super License bundles every MHD license into one purchase: Flasher, Monitor, and all three OTS map packs.

SPECS

• Flasher License: Unlocks flashing of MHD OTS maps, JB4 backend maps, and fully custom tunes. Includes a Stage 0 stock-power baseline, fault code reading/clearing, and adaptation resets, with flash times as quick as 3.5 minutes initial / 20 seconds per map switch on the MHD WiFi Adapter.
• Flash options: Exhaust burble tuning, cold-start noise reduction, exhaust flap always open in sport mode, shift brap (G8x only), top-speed (Vmax) removal, and more.
• MHD+ custom code: 4-slot on-the-fly map switching with adjustable fuel quality and power level per slot, steering-wheel-activated antilag, switchable burble per slot, on-the-fly exhaust flap control, MHD Real-Time Tuning, MaxCool heat-soak mitigation, and full 2-way CANBUS integration with the Motiv ReFlex controller.
• Monitor License: Configurable live gauge layout with up to 8 gauges across 50+ engine parameters, background CSV logging with free log analysis, and full 8HP transmission datalogging.
• MHD OTS Maps: Road- and dyno-tested Stage 1 and Stage 2 maps across 91–95 octane and E40/E85 ethanol blends.
• Supported devices: Apple iOS 10.2+, Android 6+ (OTG compatible)
• Supported adapters (sold separately): MHD WiFi Adapter, recommended for iOS & Android; ENET Cable + Lightning Adapter (iOS only)

TECH RESOURCES

• Download the MHD Flasher app, connect the MHD WiFi Adapter to your phone and the vehicle's OBD-II port, and start the app
• Initial installation takes about 3.5 minutes; later map changes take as little as 20 seconds — you can revert to the factory OEM flash at any time, no manual backup required
• Cars with the newest BMW software require a DME bench unlock regardless of production date — use the "Unlock Check" function in the MHD Flasher app's main menu to verify
• Cars produced after 06/2020 require a special unlock due to newer tuning protection — the DME must be sent to FEMTO or AutoTuner (USA and EU service available); once unlocked, MHD detects it automatically
• For Off-Road / Race Track use only
