DPF & EGR Solutions

Diesel Particulate Filter & Exhaust Gas Recirculation Remapping

What is DPF?

DPF (Diesel Particulate Filter) is a device installed in the exhaust system of diesel vehicles. Its purpose is to capture and store soot (particulate matter) to reduce emissions. Periodically, the DPF burns off the soot in a process called regeneration, converting it into less harmful gases.

 

Benefits of DPF:

  • Reduces harmful particulate emissions

  • Helps vehicles meet environmental regulations

Issues with DPF:

  • Can become blocked if regeneration fails, leading to engine issues or limp mode

  • Expensive to replace or repair

  • Regeneration is problematic in vehicles used for short trips or in cold climates

What is EGR?​

 

EGR (Exhaust Gas Recirculation) is an emissions control system that recirculates a portion of exhaust gases back into the engine's intake. This lowers combustion temperature and reduces the formation of harmful nitrogen oxides (NOx).

Benefits of EGR:

  • Reduces NOx emissions

  • Helps meet emissions regulations

Issues with EGR:

  • Can lead to carbon buildup in the intake manifold

  • Reduces engine efficiency and power

  • May cause rough idling or performance issues over time

What Is DPF and EGR Remapping?

DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) remapping refers to the process of modifying a vehicle’s engine control unit (ECU) software to alter or disable the functions of the DPF and EGR systems. This is typically done through tuning tools or ECU programming services.

What Does DPF and EGR Remapping Do?

  • DPF Remapping modifies the ECU to disable or remove the regeneration cycles and related fault codes. This is typically done after the DPF is physically removed or hollowed out.

  • EGR Remapping disables the valve operation in the ECU, preventing exhaust gases from recirculating and allowing the engine to run on fresh air only.

Benefits of DPF & EGR Remapping (Off-Road Use Only)

  • Improved Performance
    Removes restrictions in the exhaust and intake systems, resulting in increased horsepower and torque.

  • Enhanced Fuel Economy
    With optimized airflow and combustion, your engine can operate more efficiently.

  • Lower Maintenance Costs
    Avoid expensive DPF replacements and EGR valve repairs.

  • Better Reliability
    Fewer system failures and reduced risk of limp mode or breakdowns.
