About this tune
The later F60 JCW Countryman ALL4 makes ~302–306 bhp factory from the same B48 turbo four. Stage 1 is software-only; Stage 2 adds an intercooler, sports cat/decat and intake. The heaviest car here with ALL4 adds the most drivetrain loss, but crank figures are strong. 99 RON strongly recommended.
MINI John Cooper Works Countryman ALL4 tuning
The B48 2.0-litre turbocharged inline-four in the F60 JCW Countryman ALL4 is BMW's B48 under MINI badging — same engine family as the BMW 330i and 430i, running the MEVD17 or MG1CS003 DME depending on production year. The JCW Countryman is the highest factory-output MINI four, starting from 302–306 bhp / 450 Nm. Stage 1 targets up to 330 bhp / 470 Nm from OEM hardware, calibrated for clean ALL4 launch and a broad torque curve — 99 RON strongly recommended for the full figure. Stage 2 adds intercooler, decat / sports cat and intake for up to 360 bhp / 520 Nm. The Countryman ALL4 is the heaviest MINI variant, and the ALL4 drivetrain adds more drivetrain loss than the front-wheel-drive hatch models; the calibration is built for that specific combination. Every map hand-calibrated for the specific car and its fuel grade.
The F60 JCW Countryman ALL4 (2017–2024) is the largest and most powerful factory MINI — B48 2.0-litre turbo four, ALL4 all-wheel drive, 8-speed ZF automatic, Countryman SUV body. The same B48 engine family as the BMW 330i and 430i, remapped at the factory with a more aggressive JCW calibration. Samuel calibrates the F60 JCW Countryman to the same standard as the rest of the B48 MINI range, accounting for the specific ALL4 torque management, the Countryman body weight and the recommended 99 RON fuel grade. xHP gearbox calibration may be available for the ZF automatic variant.

What the JCW Countryman ALL4 map revision covers: B48 stages explained
The JCW Countryman starts from the highest factory B48 output MINI ships — 302–306 bhp / 450 Nm. Stage 1 closes the gap to the hardware ceiling: up to 330 bhp / 470 Nm from the OEM engine, calibrated for clean ALL4 launch and usable torque at road speeds. 99 RON is strongly recommended for the full Stage 1 figure; on 95 RON the calibration is adjusted to protect the engine but the peak output is reduced. Stage 2 adds intercooler, decat / sports cat and intake for up to 360 bhp / 520 Nm. The heavier Countryman ALL4 body and drivetrain loss mean the wheel power figures are proportionally lower than in the lighter hatch, but the crank output is the same. Every map is log-reviewed after the first flash before sign-off.
