Tune purchase questions
Is this bespoke custom tuning?
No. This is a preset forced-induction calibration for the supported combinations shown in the listing, not open-ended datalog development.
Will anything be shipped?
The tune file is delivered by email. A cable or other physical add-on ships separately if you purchase one.
What if I am not sure which tune fits?
Use Find Your BMW Tune or send your VIN, engine, ECU/controller ID, and modification list before ordering.
PRESET FORCED-INDUCTION TUNE
This is an affordable, pre-built calibration—not bespoke custom tuning.
- Choose one approved MAF-and-injector preset in the Tune Configurator.
- Your engine, MAF, injectors, fuel, and other selections must match the chosen preset exactly.
- Datalog review, iterative revisions, and calibration for unlisted hardware are not included.
- If your build does not exactly match an offered preset, do not order this product. Setup-specific custom tuning is handled separately through Undisputed Racing when available.
