ASV RT-120 DEF, DPF & EGR Delete | Remote Tuning by TM AG Tuning

The ASV RT-120 compact track loader is built to work hard in construction, forestry, and land clearing applications—but emissions systems like DEF, DPF, and EGR often become the weakest link. Fault codes, derates, regen interruptions, and costly downtime are common complaints from RT-120 owners.

TM AG Tuning offers professional remote DEF, DPF, and EGR delete tuning for the ASV RT-120, restoring reliability, improving performance, and eliminating emissions-related interruptions—without removing or shipping the ECU.

Common Emissions Problems on the ASV RT-120

The ASV RT-120 uses a modern diesel emissions package that includes:

• DEF (Diesel Exhaust Fluid / SCR system)

• DPF (Diesel Particulate Filter)

• EGR (Exhaust Gas Recirculation)

In real-world jobsite conditions, these systems frequently cause:

• Engine derates under load

• Forced or failed regen cycles

• DEF quality, dosing, or sensor faults

• Warning lights and limp mode

• Reduced power when pushing, mulching, or grading

For machines that spend long hours under heavy load, these emissions systems can significantly reduce productivity.

What Is a DEF, DPF & EGR Delete?

A DEF, DPF, and EGR delete involves recalibrating the engine control module so the machine no longer depends on emissions systems to operate correctly.

At TM AG Tuning, this is done through real ECU calibration, not simple fault masking. The tuning process:

• Disables DEF and SCR logic

• Removes DPF regeneration strategy

• Eliminates EGR operation

• Optimizes engine behavior for off-road use

The result is a machine that runs cleanly and consistently without emissions-related interruptions.

Benefits of Deleting DEF on the ASV RT-120

The DEF system relies on sensors, pumps, injectors, and fluid quality—all of which are failure points.

DEF delete benefits include:

• No DEF refills or freezing issues

• Elimination of DEF sensor and dosing faults

• No DEF-induced engine derates

• Lower operating and maintenance costs

For forestry and construction machines working far from service locations, removing DEF dramatically improves uptime.

---

Benefits of Deleting the DPF System

The DPF system traps soot and periodically forces regeneration cycles, which are especially problematic during heavy work.

DPF delete benefits include:

• No forced or failed regen cycles

• Reduced exhaust backpressure

• Consistent power delivery under load

• No downtime from regen-related derates

This is especially valuable when running attachments like mulchers, cold planers, or heavy buckets.

---

Benefits of Deleting the EGR System

The EGR system routes exhaust gases back into the intake, increasing soot and heat inside the engine.

EGR delete benefits include:

• Cleaner intake air

• Reduced soot and carbon buildup

• Improved combustion efficiency

• Smoother throttle response

• Better long-term engine reliability

Removing EGR allows the engine to breathe clean air and operate more efficiently under sustained load.

Real-World Performance Improvements

With a properly calibrated DEF, DPF, and EGR delete, ASV RT-120 owners typically experience:

• More consistent power when pushing or cutting

• Improved throttle response

• Reduced downtime from emissions faults

• Lower overall operating costs

• Increased reliability in demanding environments

This translates directly into more productive hours on the jobsite.

Remote Tuning – No ECU Shipping Required

Unlike many machines that require ECU removal, the ASV RT-120 can be tuned remotely.

TM AG Tuning Remote Process:

• Connect using a laptop and supported diagnostic interface

• TM AG Tuning performs the calibration remotely

• No ECU removal or shipping required

• Fast turnaround to minimize downtime

This makes the RT-120 one of the most convenient machines to tune.
