Cars the BMW S63 is fitted to.
Model, chassis and years for every car on this platform. Where a model has its own page, its name links to it.
An S63TU file is not an S63TU4 file. Send the VIN with your intake and we confirm the exact variant before quoting.

S63 setups and pricing.
Each price is the base calibration, from the live catalogue. Fuel and hardware are listed as published for each setup.
Choose a setup to carry it into Find Your Tune, or continue with S63 and choose there.

The S63, technically.
A hot-V V8 hides its heat problems until you log it. Calibration here is built around charge-air temperature, oil temperature and knock behavior under sustained load rather than a single pull, so the car stays usable after the third run instead of only the first.

Hardware checklist
- Plugs stepped colder and gapped for the boost level you are running
- Coils in known-good condition — a hot-V V8 punishes weak spark under load
- Charge-air and oil temperatures logged, not assumed
- Ethanol content measured before every logging session if you run blends
- Downpipes fitted before hybrid-turbo targets are set
Notes
- No reference output figures are published for this platform yet. Targets are set from your hardware and your logs rather than from a headline number we have not measured.
- The two S63 generations do not share a calibration. An S63TU file is not an S63TU4 file, and the VIN is what settles it.
- Heat is the limit long before boost is. Sustained-load logs matter more here than a single third-gear pull.
Calibrated from your logs.
No dyno appointment. You flash a base calibration, log the car and send it back, then we read the data and revise until it is clean.
- 01
Submit your build
Chassis, engine, full mod list and target fuel. This defines a safe calibration starting point before any file is touched.
- 02
Receive a base map
A conservative calibration matched to your hardware and fuel, flashed with your own software at home.
- 03
Log and send back
Full-throttle pulls and part-throttle data captured on our channel list, then sent over for review.
- 04
Review and revise
We read the logs, adjust the calibration and repeat until the car is running clean and on target.

- Tune pathBMW B58 Stage 1 TuneB58 Stage 1 is a custom ECU calibration on the factory turbo and factory exhaust. What it changes, what your car needs first, what to log, and what it costs.
- Tune pathBMW B58 Stage 2 Tune (Downpipe)B58 Stage 2 is the calibration for a downpiped car: less backpressure, different wastegate behaviour, and a charge-air load the stock intercooler was not sized for.
- Tune pathBMW B58 E30 TuneA B58 E30 tune is a calibration for a fixed 30% ethanol blend. What E30 buys in knock resistance, what it costs in fuel flow, and how to mix it repeatably.
- Tune pathBMW B58 E85 TuneA full-E85 B58 calibration asks 30-40% more fuel mass than pump gas. What the fuel system must support first, and why E85 is a hardware decision before a tune.
- Tune pathBMW N55 Stage 1 TuneN55 Stage 1 is a custom ECU calibration on the stock turbo and stock exhaust. What it changes, why the E-series and F-series cars differ, and what to log.

An S63TU file is not an S63TU4 file. Send the VIN with your intake and we confirm the exact variant before quoting.
- How much does an S63 tune cost?
- Stock Turbo $400 and Hybrid Turbo $500, from the Synergy catalogue.
- Which fuels does each S63 setup support?
- Stock Turbo: 91, 93 or E30. Hybrid Turbo: 93 or E30/E50.
- Is an S63TU calibration the same as an S63TU4?
- No. An S63TU file is not an S63TU4 file. Send the VIN with your intake and we confirm the exact variant before quoting.
