** OBD TO Ethernet Cable is included with the sale **

bootmod3 (BM3) is the most advanced cloud-based flash tuning platform available for the BMW S58 engine, and the go-to choice for G80 M3, G82 M4, and G87 M2 owners looking to push beyond the factory calibration. Flash your DME directly over the OBD port in minutes from your driveway — no shop visit, no DME removal.

One OTS map is included with purchase. Additional Stage 1, Stage 2, and race fuel maps are available separately. All G-series S58 vehicles require a Femto Unlock before OBD flashing is possible (see hardware notes below).

Power Gains (G80 M3 / G82 M4 / G87 M2)

proTUNING Freaks does not publish official OTS map power gain percentages for the G-series S58 platform. Real-world dyno results from the community regularly show strong gains on Stage 1 and Stage 2 93-octane and E30 maps, with further headroom on race fuel and with supporting mods. For a fully dialed calibration, custom tuning is available through the bootmod3 Tuner Directory or via any BM3-certified tuner of your choice.

Platform Features

  • On-the-fly map switching via steering wheel cruise control buttons (4 map slots)
  • Advanced flex fuel / ethanol tuning — 0% to 100% ethanol without reflashing
  • Anti-lag — build boost while stationary or rolling
  • Full map editor with close to 5,000 tuning tables
  • Live Tuning — real-time DME adjustments via integrated map editor
  • Datalogging of 70+ channels concurrently at highest throughput available
  • Live Dash — real-time in-app monitoring via configurable gauges with peak recall
  • DTC code reading, clearing, and deactivation across all vehicle modules
  • GTS startup roar, exhaust burble (fully adjustable, steering-wheel switchable)
  • Exhaust flap control (Sport Mode)
  • OPF/PPF/GPF removal support (off-road use)
  • Top speed limiter removal, custom rev limiter, custom throttle mapping
  • Boost-by-gear percentage reduction (configurable per map)
  • Transmission torque limiter disabled in software
  • Reset learned adaptations (octane, knock, Valvetronic, transmission)
  • Back-to-stock reversion and DME re-lock at any time
  • iOS, Android, Windows, macOS

Hardware & Unlock Notes All G-series S58 vehicles require a Femto Unlock to enable OBD flashing — this is different from a standard bench DME unlock and must be completed before the BM3 license can be activated. DMEs with a production date after June 2020 cannot be unlocked for tuning. This is determined by the label physically on the DME, not the vehicle's chassis or build date. If you're unsure of your DME's production date, contact us before purchasing.
