Who It's For

6.7L Cummins Ram Trucks

EZ Lynk is the default remote path for most 6.7 Cummins trucks. 2018+ Rams often need a bypass/C23-class cable alongside the AutoAgent device — we'll tell you exactly what your truck needs.

Device Path

AA3 + C23 When Your Year Needs It

Need a device?

EZ Lynk AutoAgent 3 is the usual remote path for supported years on the 6.7 Cummins. Don’t have one? Add it on your quote — we’ll recommend the right cable for your truck (e.g. many 2018+ Rams need a bypass/C23-class cable).

  • EZ Lynk AutoAgent 3 — often ~$549 street
  • 2018+ Ram bypass / C23-class cable — often ~$50–$70 street
  • EFI Live AutoCal V3 — often ~$550–$595 street

Packages

Limited vs Lifetime

Limited — $800

Custom files with a defined support window to get you dialed after the first flash and logs. Best if your truck is mostly done mod-wise.

Lifetime — $1,300

Stay with RDP for ongoing revisions as mods and goals change under Lifetime rules — best for trucks that keep evolving.

Transmission feel is often what owners notice most. Ask for a TCM-matched quote with your ECM tune (Allison, 68RFE, Aisin, 10-speed, and others by platform).

Emissions

Emissions-Intact By Default

Most street and tow customers start with emissions-intact packages aimed at cleaner tip-in, tow EGTs, and drivability — not peak-HP brag sheets. Built or off-highway projects are quoted carefully and separately. We don't publish defeat instructions.

Transmission

68RFE / Aisin Awareness

Shift firmness and torque management calibrated to match your fueling — quoted alongside your ECM tune.

Remote or Local

How It Works

Quote → pay → device if needed → add RDP as your EZ Lynk technician → install files → send a datalog → we revise. Support expectations follow Eastern Time business hours. Local meet-up available around Land O’ Lakes, Lutz, and the greater Tampa Bay area.
