Cooper S 3-door
B48 / B46 (US)
The MINI Cooper S runs the BMW B48 2.0-litre turbo four (B46 in the US — same engine). Hand-calibrated from Stage 1 software through to a built-engine turbo project. Choose your package, send your build to Samuel, and get a tune that fits how you actually drive.
MINI Cooper S 3-door Hatch tuning
Samuel starts with the F56's MEVD17 / MG1CS003 DME — its current calibration, the fuel grade you're running, and every modification on the car. Stage 1 goes in over OBD: 189–192 bhp · 280 Nm to 245–260 bhp · 360–400 Nm on stock hardware. Stage 2 is calibrated around an intercooler, decat/sports cat and intake, targeting 270–285 bhp · 420–460 Nm.

About this tune
The F56 Cooper S runs the BMW B48 2.0-litre turbo four — badged B46 on US-spec cars, same engine as the 320i and 330i, same MEVD17 / MG1CS003 DME. It left the factory at 189–192 bhp on a calibration built for global fuel variation and warranty headroom, which is where the tuning headroom comes from. The DME is accessible over OBD; no bench flash is required at Stage 1 or Stage 2. The Cooper S runs a lower-compression B48 than the JCW, with correspondingly weaker pistons — 99 RON is strongly recommended on any aggressive map, and forged internals are required before the ceiling rises safely above Stage 2.
Compatibility
This Cooper S 3-door tune runs on Bootmod3, MHD or MG Flasher — all three flash the B48 / B46 (US) over OBD. Compare platforms or see full B48 / B46 (US) compatibility.
Engine guide
What the Cooper S F56 map revision covers: B48 / B46 stages explained
The MEVD17 / MG1CS003 DME in the F56 Cooper S runs the B48's boost, torque limits and throttle response on a conservative factory setting — calibrated to handle 91 AKI and wide global fuel variation. Samuel's Stage 1 map revises those targets for your specific fuel grade and car: 189–192 bhp · 280 Nm to 245–260 bhp · 360–400 Nm, OBD only, no hardware required. Stage 2 recalibrates around the expanded airflow and cooling from an intercooler, decat/sports cat and intake, targeting 270–285 bhp · 420–460 Nm. Every map is log-reviewed after the first flash; Stage 3 is consultation-first and built bespoke around the forged-piston and big-turbo spec you submit.
Stage 1
245–260 bhp · 360–400 Nm
ECU/DME software only, flashed via the OBD port on stock hardware. Sharper throttle, a much broader torque curve and the response the Cooper S should have shipped with. The most cost-effective single change on the platform. 99 RON strongly recommended for the full figure.
Every MINI Cooper S tune Samuel produces is calibrated individually for the specific car, fuel grade and installed hardware, and reviewed against your data logs before sign-off — never a base map loaded and left.

FAQ
Cooper S 3-door tuning — frequently asked questions
Samuel delivers the F56 map directly to your BM3, MHD or MG Flasher account within 24 hours of payment — personally calibrated, not auto-generated. You flash it yourself over OBD in about 15 minutes, no hardware removal required.
Yes. The original B48 / B46 (US) stock file is supplied before you flash, and you can return the F56 to its factory calibration at any time.
A factory warranty can be voided if MINI/BMW attributes a failure to the tune — that's a personal call. Samuel's F56 maps are calibrated to stay within the mechanical limits of the B48 / B46 (US) hardware, and because the tune reverses to stock before any dealer visit, many Cooper S owners run tuned cars without issue.
BM3 is the most widely used for the F56 B48 and the right choice if you want realtime monitoring via the app. MHD has a strong data-logging toolset — useful for checking lambda and intake temperatures on a low-compression Cooper S after each stage change. MG Flasher supports the MG1CS003 DME fully and suits owners who prefer the MG ecosystem. The calibration Samuel delivers is the same on all three; the choice is the flashing tool, not the map.
Yes. After your first session on the F56, send your logs back through whichever platform you're running. Samuel reviews them before sign-off and revises the map if needed — it's not a file delivered and closed.
