BEFORE YOU ORDER

Common Questions

Clear answers before you choose a package.

How do I know which package fits my truck?

Choose your model-year range first. The exact VIN and truck configuration are collected before applicable file delivery. Use the Setup Finder or contact us before ordering for a chassis cab, F-550, retrofit, or unusual configuration.

What is the difference between Ironline Tuning and ASAP Calibrations?

Ironline selections use Ironline’s own calibration library. ASAP selections use files supplied by ASAP Calibrations. Available files and support terms depend on your selected product.

What is the difference between 4 Weeks and Full Support?

Four Weeks includes supported-file access and written support for four weeks. A successfully installed file remains installed afterward. Full Support provides ongoing supported-file access and written support for the original VIN and confirmed configuration, subject to the selected product terms.

Why can a complete order arrive in multiple packages?

Hardware can ship from separate fulfillment locations, so one order can have multiple tracking numbers and delivery dates. The Support Center explains how to check every package.

When is my order processed?

Orders are processed within 1–2 business days. VIN is optional when ordering; we verify it afterward before releasing Ironline files or submitting an ASAP file order. Follow the connection instructions for your selected provider.
