Bluespark S55 Performance Chip Tuning Box for BMW M2 Competition (M2C) F87, M3 F80, M4 F82/CS - Plug & Play Piggyback Power Module, ECU Safe Stage 1 Remap Alternative, 5 Maps, Dyno Proven Gains

Bluespark Power Module for BMW S55 - M2 Competition F87, M3 F80, M4 F82 / M4 CS

Unlock serious real-world pace from your S55 twin turbo straight-six with the Bluespark petrol performance module. Designed for the M2 Competition, M3 F80 and M4 F82, this inline tuning unit delivers a harder hit through the revs, earlier boost, crisper throttle feel and effortless punch on the road or track. It installs via OEM-style connectors, leaves the factory ECU unopened and can be removed at any time for a clean, stock return.

At MJ Modifications we have fitted and used these on multiple S55 cars and the transformation is exactly what keen BMW M drivers want: stronger torque where you use it most, surging acceleration that holds on to the redline and smooth, factory-like refinement in daily driving. Customers consistently come back impressed with the value and the performance per pound.

What you get

• Stronger shove across the rev range for confident overtakes and faster lap times
• Earlier spool for a more urgent feel and quicker on-throttle response
• Fully removable hardware that does not involve opening or flashing the ECU
• Can be updated for future vehicles to maximise long-term value
• Durable alloy control unit with engine-bay rated sealing
• Five adjustable power maps to suit fuel quality and driving style
• 28-day return period for peace of mind

Rolling road results

Before: 409 PS and 550 Nm

After: 515 PS and 661 Nm

Figures from testing; results vary by vehicle, fuel and dyno. The key benefit is stronger torque earlier, sustained pull to the limiter and sharper response in every gear.
