2022-2024 RAM
2022–2024 RAM Cummins trucks can be tuned on the original ECM without an ECU unlock.
We offer three tuning options depending on the transmission, desired tuning, and tuning device:
2022 Cab and Chassis trucks do not currently support SOTF.
The sections below explain the available tuning methods and the procedures required for each.
For 68RFE trucks only, we can provide an Optimized Stock File using EFI Live.
This option uses the truck's original ECM and does not require an ECU unlock.
The calibration must be loaded onto an EFI Live AutoCal V2 or V3 handheld and then Full Flashed from the handheld.
Pass-through flashing will not work for this procedure.
This option is intended for customers who want an optimized stock-style calibration. Single tunes and Switch-On-The-Fly tuning are available through EZ Lynk or HP Tuners where supported.
For EFI Live setup, linking, reading, flashing, and other procedures, please follow our complete EFI Live instructions:
EZ Lynk supports both single tunes and Switch-On-The-Fly tuning where supported.
2022 Cab and Chassis trucks do not currently support SOTF.
The original ECM can be tuned directly. An ECU unlock is not required.
For EZ Lynk setup, linking, reading, flashing, and other procedures, please follow our complete EZ Lynk instructions:
HP Tuners supports both single tunes and Switch-On-The-Fly tuning where supported.
2022 Cab and Chassis trucks do not currently support SOTF.
The original ECM can be tuned directly. An ECU unlock is not required.
HP Tuners tuning requires:
The SGM bypass cable must be connected whenever communicating with the applicable modules through HP Tuners.
Before we can prepare your tune, you will need to read the original ECM and send us the stock file.
Help → Resync Interface
Accessory mode will not work.
Flash → Read Vehicle
The default HP Tuners location is commonly:
Documents → HP Tuners → Logs and Tunes
We will use the stock read to prepare your tuned file.
If we request an InfoLog, create it with the original ECM installed in the truck.
The InfoLog allows us to see additional controller and calibration identification information that may not be obvious from the tune file alone.
Save the InfoLog and send it along with the corresponding ECM read.
Send the files to Support@SpeedFarmGarage.com, or reply to your order email.
Battery voltage must remain stable throughout programming.
We recommend connecting a suitable battery charger, particularly if battery condition is unknown or the truck has been sitting for an extended period.
Loss of power during an ECM write can damage or corrupt the controller.
File → Open
Help → Resync Interface
This allows the interface to synchronize its current credits and licensing information.
Accessory mode will not work.
Flash → Write Vehicle
HP Tuners licensing is performed for the appropriate calibration/module as shown by VCM Editor. Follow the licensing prompts before continuing.
Do not disconnect the laptop, tuning device, SGM bypass cable, ECM, battery charger, or vehicle power while programming is in progress.
The truck is now ready for the modifications accounted for in the tune to be installed.
