Power comes after the data.
The same discipline applies on every platform, the S58 included.
- 01
Component limits are respected
Targets are set against what the factory hardware on this platform can hold, so the car stays usable as a daily driver.
- 02
The calibration follows your logs
Boost target against actual, air-fuel ratio, ignition timing, knock activity and fuel pressure are read on every revision round.
- 03
Revisions continue until it is on target
Tuning is a conversation. Logs come back, the file is adjusted, and the loop repeats for as long as it takes.
