TM AG Tuning offers a specialized tuning solution for 2017–2024 PACCAR MX engines. These newer trucks rely heavily on the Aftertreatment Control Module (ACM), so our process focuses on programming the ACM directly to remove DEF and DPF related issues. The EGR is still active.

This package includes a TM AG Tuning Cummins Interface along with an ACM bench harness. Together, these tools allow you to read the ACM cleanly and safely from the truck or on the bench. This will be live tuning. We build a custom ACM tune that disables the DEF and DPF systems and eliminates constant regens, derates, and aftertreatment faults.

Before tuning, any active emissions codes must be cleared. This ensures the ACM read is clean and prevents fault codes from being carried over after the programming.

Our PACCAR ACM tuning improves reliability, prevents derates, stops aftertreatment-related downtime.

If your truck is stuck in regen, constantly throwing aftertreatment codes, or losing power due to DEF/DPF issues, this ACM-focused tuning package is the proper solution for all 2017–2024 PACCAR MX engines.

By purchasing this remote tuning service, you acknowledge that you are responsible for any damages to components that may occur due to disruptions such as an internet outage, laptop power failure, or similar issues. Ensuring a stable setup is crucial for a successful tuning experience.

Note:  Some newer dashes may show the DEF low symbol. The Dash is looking for a DEF level but since the emissions are removed the dash does not see a DEF level. Before tuning, any active emissions codes must be cleared. This ensures the ACM read is clean and prevents fault codes from being carried over after the programming.
