F96 · S63 ENGINE · BM3 CUSTOM CALIBRATION
BMW F96 X6 M — Custom BM3 Tune (S63)
Logged, verified, revised. Documented in writing. Yours to keep.
A custom bootmod3 calibration for the F96 (S63) — built from datalogs on your car, not a map off a shelf. We start from what your engine is actually doing in fuel trims, timing, knock, and load, and revise against the next log until the math and the data agree.
How we approach it
Math first, datalogs second, marketing claims a distant last. We don’t publish dyno numbers we can’t reproduce; we tune to what your specific car does on the fuel you actually buy.
The matched Stage Kit for this engine — components + the calibration sold as one decision — is the Stage 2 Kit — S63. 8% under buying the parts and tune à la carte.

How we calibrate this platform.
The process is the same on every car we touch: datalogs in, ignition and fuel changes out, a revision log in writing.
Before you tune.
How long until I have a working tune?
4-5 business days from datalog receipt for Stage 1; 7-10 days for Stage 2.
Do I need supporting hardware for Stage 2?
Chargepipe and a fuel system check are recommended. E30 flex requires a flex-fuel kit on chassis that don't ship one factory.
Can I revert to stock for warranty service?
Yes. BM3 supports non-destructive stock revert. Most customers revert before dealer appointments and re-flash after.
What VIN do I enter at checkout?
The 17-character VIN of the car you're tuning. It appears on the driver-side dash, door jamb sticker, and registration.
