2022-2024 Cummins All in One Kit (DIY Kit) | Ram 6.7L

🚀 Stock ECM power added through EZ Lynk tuning is finally here for the 22–24 Cummins applications.

Everything you need to unlock your 6.7L Cummins from home — engine tuning, transmission calibration, exhaust, and the hardware to install it, backed by tuning support for as long as you own the truck. 💪

✅ Factory ECM Compatible — No Swap, No Mail-In Unlock

This is the big one: your stock ECM stays exactly where it is. Flashing this way is fully safe for your factory ECM — nothing about it puts your stock computer at risk down the road, now or later.

Thanks to updated EZ Lynk support, most 2022–2024 6.7L Cummins trucks now flash directly through the OBD-II port on the stock ECM. Plug in, load your custom tune, and flash — no ECM swap and no sending your ECM out for an unlock.

💰 No more dropping another $3,000+ on an ECM swap just to tune your truck. The capability to do this entirely yourself — with nothing but an EZ Lynk — is finally here.

Already running a swapped or previously unlocked ECM? You're still fully supported with this kit. 👍

📦 What You Get

Exhaust (pick one)

• 🔥 Race pipe
• 🔥 Full 5" system

Emissions hardware

• EGR upgrade solution, matched to your exhaust selection

Required bypass hardware

• 🔌 2018+ Security Gateway bypass cable (needed for flashing on these trucks)
• 🔌 CCV switch-on-the-fly cable, for setups using SOTF

Flash device

• 📲 EZ Lynk AutoAgent 3 — our pick for this platform for ease of use and flash reliability

⚡ Engine Tuning

Custom power-added calibration built around your specific truck and mods, with ongoing support included for the life of your ownership. Available as:

• Single fixed-power tune (0–200 HP baseline)
• Switch-on-the-fly, multiple power levels (0–200 HP baseline)
• Higher power levels for trucks with supporting fuel, turbo, or injector upgrades

Stated HP ranges assume a stock or near-stock truck — every calibration is tailored to your actual setup, not a generic file. ✅ Safe, custom, and built for your combo.

🛠️ Transmission Tuning

68RFE — included in this kit Fully custom calibration covering:

• Shift timing and shift point scheduling
• Line pressure (stock or increased, for better clutch holding capacity)
• Torque management matched to your tune
• UD pulse disable option
• Locked/unlocked shift behavior and TCC lockup timing
• Shift feel tuned firmer or smoother
• Tow vs. daily-driver shift strategy
• Calibration built for stock or built 68RFE units

Whether you're chasing better towing manners, crisper daily shifts, or a more aggressive setup, the 68RFE calibration is built around your power level, tire size, and how you actually drive the truck. 🚛

AISIN transmission Sold separately — not included in this kit. Reach out if you're running AISIN and need it added.

🔁 Switch-on-the-Fly

Change power levels without a full re-flash. Depending on your build, SOTF is handled via the CCV-style cable or DEF-gauge switching. Hardware needed varies by configuration.

♾️ Ongoing Tuning Support

Included for as long as you own the truck:

• Add new modifications to your calibration as your build changes
• Access to special tuning functions (limiter adjustments, rumble idle, 12V idle, low boost fueling, and more — availability depends on your exact hardware)
• Continued support as your setup evolves

📋 Before You Order

• SGW bypass cable is required on 2018+ trucks and is included in this kit
• Factory ECM applications need no swap and no mail-in unlock — the stock ECM stays in the truck, safely, permanently
• If you already have a compatible swapped or unlocked ECM, you're still covered
• Double-check your exact year, ECM configuration, and transmission type before ordering — hardware and tuning needs vary by build

⚠️ Off-road use only. Not legal for emissions-controlled vehicles operated on public roads.
