PRODUCT DETAILS

MATCHED CALIBRATION SERVICE

Start your cammed LS with a matched Holley file.

Customer-specific startup and idle baseline, with one startup log review and one corrective revision. Not a completed street tune.

Custom Holley EFI Startup File for Cammed and Modified LS Builds

This service provides an initial custom calibration for a mechanically complete cammed or modified naturally aspirated LS combination using Holley Terminator X, Terminator X Max, HP, or Dominator EFI.

Included

  • Engine, camshaft, injector, and fuel-system configuration review
  • Initial cranking fuel, startup enrichment, idle airflow, and base ignition settings
  • Cam-specific idle strategy based on the supplied cam card and combination
  • One startup datalog review and one corrective revision

This is a startup calibration file, not a completed remote or street tune. Final drivability, load, and wide-open-throttle calibration require the appropriate tuning package.

Customer Requirements

Provide the current Holley Global File, complete engine specifications, cam card, injector data, fuel type, ignition system, MAP sensor, throttle body, transmission details, and all modifications. Wiring, fuel pressure, sensors, and mechanical condition must be verified before calibration.

Purchase this service to begin intake and file review.
