Answers before and after your order.

Open the Get Your Files walkthrough. Ironline orders use Ironline’s technician email; ASAP orders use the ASAP invitation. After file delivery is confirmed, open Vehicle → ECU Profiles. The walkthrough includes official app screenshots.

Use the provider and year file guide. ECM means engine; TCM means transmission. Available profiles depend on your confirmed VIN, provider, hardware, and selected package. Read the exact profile description before choosing a file.

The physical switch is a separate hardware selection. Confirm it appears in the cart or order summary. The switch only changes power levels with a compatible file labeled “SOTF”. Files labeled “Single” run one fixed power level and do not respond to the switch.

A successfully installed file stays installed on the truck. For Ironline orders, the four-week file-access period starts when files are sent, not when you first flash. For ASAP, ask us to confirm the dates on your order. Missing profiles can also indicate a connection issue. Check the access explanation before buying another package.

Full Support applies to the original VIN and confirmed configuration. A different truck or major configuration change may need new files or a new purchase. Send the existing order details so we can confirm the available options.

Use the installation guide finder. Match the actual hardware and connector, as well as the year. Confirm the VIN, provider, files, and installation/flashing sequence before starting hardware work or flashing.

Yes. The support form accepts requests without an order number. Include the checkout name and email and, if you know it, the approximate order date. Check spam and alternate email addresses for your confirmation.

The selected variant and eligible add-ons determine your setup subtotal. Review the cart and final checkout total, including any applicable discount, taxes, and shipping. Discount codes are checked at checkout. For options not shown, send a custom quote request before ordering.

Reply to the same email thread when you have one. If no reply arrived, check spam, then select “Follow-up on an existing request” in the support form and include the original message date. Support hours are Monday–Friday, 9 AM–5 PM Central.

Start with your truck's correct model-year range and review the configuration choices on that product page. If fitment is still unclear, submit the structured support form before ordering.

Yes. We offer complete setups for 2013–2018 and 2019–2021 Ram 2500 and 3500 pickups with the 6.7L Cummins. Cab-and-chassis 3500/4500/5500 trucks and 2022-and-newer trucks are not currently supported. Each product page lists the exact fitment.

An EZ Lynk AutoAgent with the connection hardware your truck year needs, an Ironline calibration (Single-Level or Shift-On-The-Fly at the same price), your choice of a 4-inch race pipe or 5-inch full exhaust, and 4 Weeks of support. EGR hardware is an optional $200 add-on, and Full Support is an optional $200 upgrade. Components may ship separately with separate tracking.

Not by default. On Cummins setups, the EGR kit is an optional $200 add-on that you choose on the product page. (Complete Powerstroke setups include EGR hardware.)

Yes. The five-position switch is an optional $99 add-on for supported 2013–2021 Cummins SOTF calibrations. It only works with a compatible SOTF calibration and ships only when selected.

We match calibrations to 68RFE and Aisin automatic trucks. The two are not interchangeable, so tell us your exact transmission when you order. Manual-transmission trucks are not currently offered online; email us with your VIN first.

No. The listed Cummins exhaust options fit 2019–2021 trucks with standard rear suspension only. If your truck has factory rear air suspension, email us before ordering.

No. Ironline Diesel is not affiliated with Ram, Stellantis, Cummins Inc., or Ford. Brand names are used only to describe fitment. All products are intended for off-road and competition use only where permitted.

No. Exact components, available options, and price depend on the selected truck and configuration. The product page and selections shown in the cart control the final order.

Follow the instructions provided after checkout and submit any requested truck or configuration information completely. Missing information can prevent the correct order or calibration details from being processed.

Both options are sold through Ironline Diesel and use EZ Lynk. Choose one calibration provider.

The provider choice changes your tuning files. Device and hardware follow the selected package; tuning-only purchases exclude both.

Choose 4 Weeks or Full Support separately for file access and support. Email support is Monday–Friday, 9 AM–5 PM Central with either provider.

After ordering, follow the connection instructions for the provider shown in your order. Available files depend on your truck and purchased package.

Start with Ironline's structured support form. Include the order number, truck details, selected calibration provider, current file, relevant codes, and a clear description so the request can follow the correct support path.

Not always. Complete setups can ship in multiple packages. Ironline provides separate tracking for every package as that tracking becomes available, so review each number connected to the order.

A delivered tracking number can cover only part of a complete setup. Review every shipment. If the contents are unclear, send the tracking numbers and a photo or list of what arrived so we can check the remaining components. Open tracking help.

Support is handled by email Monday–Friday, 9:00 AM–5:00 PM Central.

Email requests are reviewed during support hours. Keep follow-ups in the same thread.

Include the order number, model year, selected calibration provider, current file, relevant codes, a clear symptom description, and useful photographs or videos. Complete information reduces unnecessary back-and-forth.

Support is handled by email. Use the support form or email support@ironlinediesel.com. Keep follow-ups in the same thread.

Ironline can review information related to the purchased package and setup process. An underlying mechanical condition may still require hands-on diagnosis by a qualified local technician.
