Truck Tuning

Review laptop, tuning-tool, file-service or ECU mail-in routes using your VIN and installed engine details.

Your exact application, controller, readability and licensed protocol are reviewed before a quote or job is confirmed.

Truck details

Optional chassis make for review. VIN and installed engine details are reviewed separately; this choice does not confirm compatibility or select a method.

VIN, installed engine and model year are reviewed together.

Tune choices

EMO ON is an explicit request. Engine and controller suitability are reviewed.

Tool and method review

2022+ PACCAR MX/PX engines require ECU mail-in. Unknown engine or model year remains under review.

File service requires exact application, tool and network review. Without a suitable supported tool, ECU mail-in is reviewed. A method shown here does not confirm suitability.

Wait for confirmed shipping instructions before sending your ECU. Costs, processing timing and return arrangements are confirmed in your quote.

Before you send your request.

Which trucks does this Cummins HD service cover?

We support Cummins HD ECM families CM870, CM871, CM875, CM2150, CM2250, CM2350, and CM2450. Your installed engine, ECM, calibration, setup, and tuning method still need review. Pickup and light-duty tuning are outside this service.

Who creates your tuning files?

HDTruckTunes creates every custom tuning file in house. We use our own files, built for your truck, modifications, and tuning goals. We never use anyone else’s tuning files.

What do I need for remote tuning?

A laptop with TeamViewer and a compatible J1939 device connected to your Cummins HD truck. Request a preferred date and time, or a Rapid-Tune session within 2 hours subject to confirmed availability. We review your setup and confirm the session.

What does the VIN lookup fill in?

Available NHTSA factory details can include year, make, model, and engine information. VIN records vary. Confirm the details and add engine serial number, current tuning, and truck modifications yourself. VIN lookup does not confirm compatibility.

When will I pay or receive hardware?

Send your request for review first. We confirm compatibility, final pricing, availability, and any hardware shipping quote before payment or fulfillment. Hardware shipping is confirmed for the United States and Canada. This form does not collect payment.

Will the 9-pin adapter fit my setup?

The adapter offered here is for Auto Agent 3 and supported 9-pin diagnostic ports. Tell us your diagnostic connector and current Auto Agent version so we can review fitment.
