Quick Answer

The BMW CS DME flash applies the factory BMW M3 CS production calibration to your G80 M3 or G82 M4 DME. This delivers approximately 530 HP using BMW's own signed software — no third-party ECU unlock, no warranty-voiding hacks. The original calibration is backed up before flashing. Remote ENET session takes 30 minutes. Fully reversible.

BMW CS DME Engine Flash for G80 M3 and G82 M4 — upgrade to 530 HP / 650 Nm using the genuine factory M3 CS calibration for $299 USD. Speed limiter removed from 250 km/h to 300 km/h (186 mph). Improved throttle response, optimized boost targets, sportier exhaust mapping with overrun pops. OEM BMW software — no ECU unlock required, no dealer flags, fully reversible.

Supports all current software versions including 11/2025.30 and 11/2025.40. 20-minute remote flash via ENET cable and TeamViewer. M-TRI UPGRADE — professional BMW remote coding and flashing, Auckland NZ, worldwide service.

Your G80 M3 makes 473 HP — the M3 CS makes 543. Same engine, different software.

  • You're sitting on an S58 that BMW already validated for 543 HP in the CS model — but your standard M3 only gets 473 (or 503 in Competition)?
  • The top speed limiter cuts you off at 250 km/h when the car is clearly capable of much more?
  • You want CS-level throttle response and exhaust character without the $30,000+ premium of buying an actual CS?

BMW CS DME Engine Flash — G80 M3 / G82 M4
