MG Flasher

MG Flasher is a mobile tuning app designed for BMW and Supra engines (B48, B58, S58, N63, S63, N74) that flashes via ENET Wi‑Fi. Flashing on ENET takes as little as 15–20 seconds, with initial ECU unlock typically 4–6 minutes. The app unlocks a broad range of capabilities, including custom options to tailor performance, exhaust, cooling, torque, and coding; and switchable maps on‑the‑fly—the world’s first solution for B58/B48—allowing you to switch maps without reflashing the car.

MG Flasher also adds on‑the‑fly dynamics for tuning confidence: burble intensity control, flex fuel calibration, max cooling, and torque‑limit adjustments; plus speed limiter and startup options on select software. It provides sport gauges, OTS and custom maps, real-time data logging, cloud log viewing, diagnostics, and adaptation resets while preserving the CVN and flashing counters. Supported vehicles span BMW platforms from F20/F21/F40 through G80 and others, making MG Flasher a versatile tool for enthusiasts and DIY tuners alike.
