Stage pricing for the F57
Cooling, downpipe, fueling — the ceiling worth chasing on factory turbos.
Build this stage Stage 2 methodologyBigger fueling, often a hybrid or Phantom turbo. Per-car.
Build this stage Stage 3 methodologyThe F57 is the MINI you buy for the feeling of the roof going down on a good road — the convertible version of the F56 hardtop, same B48 underneath, built around open-air character rather than the last tenth of sharpness.
Mechanically it's the hatch: the Cooper S B48 (around 192 hp) and the JCW (roughly 231) tune the way they do on the F56 (full story there, LSPI caution included). The convertible adds some weight and a little structural give versus the fixed roof — the usual open-top trade — so it's the MINI that prioritizes the experience over the stopwatch, the same way the open-top M cars higher up the range do.
The honest read: if you want the sharpest small MINI, the two-door hardtop is it; if you want the same character with the sky overhead, the F57 gives up very little to get there. Same engine, same build, just more sunshine.
So the convertible MINI is exactly what it looks like — the F56's fun, topless — and it tunes no differently for the privilege.

Set the F57 as your garage vehicle and the rest of the store filters to what fits it.
Set vehicleBefore you tune.
Will my dealer flag the tune at service?
The bootmod3 flash is non-destructive and reversible. Revert to stock before a dealer appointment and the ECU is back to factory in a few minutes; re-flash after service. We document the revert step in writing so the next person opening your file knows what's there.
Is it safe for the engine?
Every tune we ship has been datalogged on the car it was written for. We look at knock counts, fuel trims, boost behavior, and intake temps before we sign off. If the numbers don't sit right, we revise. That review and the revision policy are built into what the tune costs.
How long until I have a working tune?
Most calibrations turn around in a few days. We log, review, and revise before anything ships — we would rather get it right than get it out fast.
Can I go back to stock?
Yes. bootmod3 supports a stock revert that returns the ECU to factory calibration in under five minutes. The flash is non-destructive — nothing in the BMW DME is permanently modified. Most owners revert before trade-in.
