Cummins ISX / X15 (CM2250, CM2350) — Remote Tune

Custom remote ECM calibration for the Cummins ISX and X15 platform — covering CM2250 and CM2350 control modules — as fitted in Kenworth, Peterbilt, and Freightliner Class 8 trucks. Three calibration stages are available to match your operational priorities.

What's included

• Stage 1 — Economy and baseline optimization. Fuel delivery, timing, and idle parameters are refined for improved efficiency and drivability with no hardware changes required.
• Stage 2 — Enhanced performance calibration. Torque and power delivery are increased beyond factory limits for stronger pull and improved response under load.
• Stage 3 — Maximum calibration. Full-envelope tuning targeting peak output; emissions-control hardware considerations apply and should be discussed before ordering.

How it works

Tuning is performed via a live TeamViewer remote session. You will need a Windows laptop connected to your truck's diagnostic port with a compatible heavy-duty interface. Session scheduling and ECM confirmation are handled at time of purchase.

These calibrations are intended for closed-course competition, off-road, and non-emissions-regulated use only. Not for use on public roads where emissions regulations apply.
