TM AG Tuning provides professional DEF, DOC, and EGR delete tuning for the TYM 1104, delivering improved reliability, smoother operation, and fewer interruptions during critical work. We also support the TYM 1054, using the same proven tuning approach.

Common Emissions Problems on the TYM 1104

The TYM 1104 uses multiple emissions components to meet regulations, including:

• DEF (Diesel Exhaust Fluid / SCR system)

• DOC (Diesel Oxidation Catalyst)

• EGR (Exhaust Gas Recirculation)

While effective for emissions compliance, these systems often cause real-world issues such as:

• Warning lights and fault codes

• Engine derates under load

• Poor throttle response

• Increased fuel consumption

• Costly repairs and maintenance

For tractors used in agriculture, these systems can become more of a liability than a benefit.

What Is a DEF, DOC & EGR Delete?

A DEF, DOC, and EGR delete involves recalibrating the tractor’s ECU so it no longer relies on these emissions systems. When done correctly, this eliminates related faults and restores predictable engine behavior.

At TM AG Tuning, this is not a “light shutoff.” We perform real ECU calibration, ensuring:

• DEF and SCR logic is fully disabled

• DOC monitoring is removed correctly

• EGR function is eliminated without drivability issues

• Engine strategies are adjusted for agricultural workloads

Benefits of Deleting DEF on the TYM 1104

Deleting the DEF system removes the need for diesel exhaust fluid entirely.

Key benefits include:

• No DEF refills or freezing issues

• Elimination of DEF-related fault codes

• No DEF-induced derates

• Lower operating and maintenance costs

For tractors working long hours or in remote areas, DEF removal significantly improves uptime and reliability.

Benefits of Deleting the DOC System

The DOC (Diesel Oxidation Catalyst) plays a role in emissions monitoring and exhaust treatment but can contribute to restrictions and fault conditions.

DOC delete benefits include:

• Reduced exhaust backpressure

• Fewer exhaust-related faults

• Improved engine responsiveness

• More consistent power delivery

Removing DOC-related logic helps the tractor run smoother, especially under sustained load.

Benefits of Deleting the EGR System

The EGR system recirculates exhaust gases back into the intake, which can increase soot buildup and reduce engine efficiency.

EGR delete benefits include:

• Cleaner intake air

• Reduced soot and carbon buildup

• Improved combustion efficiency

• Smoother engine operation

• Better long-term engine reliability

For agricultural tractors, removing EGR often results in more stable performance and reduced maintenance.

Real-World Performance Improvements

With a properly calibrated DEF, DOC, and EGR delete, TYM 1104 owners typically experience:

• More consistent power under load

• Improved throttle response

• Reduced downtime from emissions faults

• Lower operating costs

• Increased reliability during critical work

This makes a noticeable difference during tasks such as tillage, baling, loader work, and PTO-driven applications.

ECU Bench Tuning Required for TYM 1104 & TYM 1054

For the TYM 1104 and TYM 1054, the ECU must be removed and shipped to TM AG Tuning for bench programming.

Why ECU Shipping Is Required

• These tractors do not support full remote tuning

• Bench access allows proper calibration and verification

• Ensures a clean, reliable delete without shortcuts

What to Expect

• Clear ECU removal instructions

• Fast turnaround once received

• Professional calibration tailored to your tractor

Shipping is straightforward, and this method ensures the highest-quality result.
