MATCHED CALIBRATION SERVICE
A first-start file for your naturally aspirated LS.
Customer-specific Holley EFI startup calibration, including one startup log review and one corrective revision. Final tuning is separate.
Custom Holley EFI Startup File for Naturally Aspirated LS Builds
This service provides an initial custom calibration for a mechanically complete naturally aspirated LS combination using Holley Terminator X, Terminator X Max, HP, or Dominator EFI.
Included
- Engine displacement and firing-order configuration
- Injector and fuel-system setup review
- Initial startup, idle, cranking-fuel, and base ignition settings
- One startup datalog review and one corrective revision
This is a startup calibration file, not a completed remote or street tune. Final drivability and wide-open-throttle calibration require the appropriate tuning package.
Customer Requirements
Provide the current Holley Global File, engine specifications, injector data, fuel type, ignition system, MAP sensor, throttle-body information, transmission details, and all relevant modifications. Wiring, fuel pressure, sensor operation, and mechanical condition must be correct before calibration.
