2022 - 2024 Ram Cummins 2500 3500 4500 | MM3

Upgrade your 2022–2024 Ram Cummins with MM3 custom tuning designed to improve horsepower, torque, fuel economy, towing performance, and overall drivability. 

Available power levels range from optimized stock through 200 HP, with optional CSP4/CSP5 switch-on-the-fly tuning for quick power level changes while driving. 68RFE applications can also be paired with transmission tuning for improved converter lockup, line pressure, shift strategy, and torque management. 

These trucks require a compatible 2019–2021 model year PCM for tuning, along with an MM3 device and the appropriate licensing.

Cummins CSP4/CSP5 Pass Through Switch:

CSP4/5 pass through switch allows you to change power levels on the go, or commonly referred to "Switch on The Fly". They do NOT require you to stop the truck and wait 5 minutes for the truck to re-flash, you just turn the rotary dial to the position of the tune you want while the truck is running or driving down the road and carry on. These switches plug into the OBDII port and have a pass through port allowing you to plug something else with a OBDII plug into it, such as a Monitor.

Transmission Tuning (Available Only on 68RFE Transmission) 

Benefits of Transmission Tuning

• Earlier converter lockup
• Increased line pressure
• Revised shift strategy to reduce sluggish shifting
• Earlier downshifts with less throttle input
• Revised torque management

Custom transmission tuning can improve shift behavior, towing performance, and how the transmission responds to increased engine power.

How to tell the difference in auto transmissions

• 68RFE - Transmission pan looks like a turtle shell. The dipstick is on the passenger side of the engine bay.
• Aisin - Transmission pan is flat and says Aisin on the side of it. The dipstick is on the driver side of the engine bay.

Requirements

IMPORTANT:

• All vehicle and transmission tuning requires an MM3 Device + appropriate licensing for deployment, unless you already have a compatible MM3 Device and the required licensing.
• A Windows-based computer is required to flash the tuning to your vehicle and/or transmission.
• Detailed instructions are included with every tune and walk you through downloading the tune file to your MM3 Device and flashing it to the vehicle.
• This process requires a 2019–2021 model-year PCM.
• Compatible PCM part numbers will typically begin with a “4”.
• The PCM date code should typically be from 2019, 2020, or 2021.
• PCM availability is limited due to these units becoming increasingly difficult to source.
• In some cases, a new, unprogrammed factory PCM can be used.
• This requires additional programming on our end and may result in additional costs.
• SKIM data is transferred using the MM3 Device.
• Please allow a couple of days for the SKIM transfer process to be completed.
