Holley EFI LS NA Startup Calibration File

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.
