ECU REMAPPING SOLOUTIONS

DPF Removal / Delete

DPF Removal / Delete

Removing the DPF (Diesel Particulate Filter) from a vehicle offers substantial improvements in both performance and efficiency.

The Process involves removing the internal filter from the exhaust system while keeping the outer casing intact. The exhaust system is disassembled, and a small access point is cut into the DPF canister. The internal filter is then carefully removed, and the access point is welded shut. Alternatively, bypass pipes can be installed for customers who prefer to retain the original DPF canister.

After the physical removal, Zentunes software will reprogram the ECU to remove any DPF related functions, preventing future regeneration cycles and warning lights. This is crucial to ensure the vehicle operates smoothly without sensing the missing filter.

Before proceeding, check local regulations to ensure DPF removal is legally
permitted in your location

EGR Bypass / Removal / Delete

Governmental bodies have implemented stringent emission targets prompting vehicle manufacturers to develop new methods to reduce emissions. One such method is the EGR (Exhaust Gas Recirculation) system. While the EGR valve effectively reduces emissions, it can negatively impact engine efficiency and reliability.

Zentunes EGR (Exhaust Gas Recirculation) Removal Service addresses common issues associated with the EGR system, which often compromises engine efficiency and reliability. With this Service, you can now provide your customers with a full EGR bypass or removal service, improving vehicle performance and reducing maintenance costs.

The Process starts with the EGR valve which is first blanked to prevent exhaust gases from re-entering the intake system. Next, the ECU is reprogrammed to remove all EGR-related functions, ensuring the valve remains closed at all times. This process is vital for preventing future EGR-related issues.

P Code / Fault Code / DTC Delete

For workshops modifying vehicles for performance or motorsport, removing fault codes from the engine management system is essential. Zentunes P Code / DTC (Diagnostic Trouble Code) Delete Service permanently removes specific fault codes from the ECU, preventing dash lights from being displayed and avoiding limp mode.

This Service is particularly useful when removing components such as swirl flaps, EGR valves, or other modules that may trigger fault codes. Zentunes software ensures a clean and error free engine management system.

AdBlue (SCR) Removal / Delete

AdBlue is a chemical liquid used in Selective Catalytic Reduction (SCR) on diesel vehicles in order to reduce NOx levels. The AdBlue fluid (Diesel Exhaust Fluid) is injected into the exhaust system just before the SCR catalyst. The introduction of AdBlue into the exhaust gasses generates a chemical reaction inside the SCR Cat which results in NOx being converted into Nitrogen and Water Vapor. AdBlue was introduced by vehicle manufacturers in order to hit the stringent emission targets set out by governmental bodies. 

Zentune offers an AdBlue/SCR (Selective Catalytic Reduction) Delete Service allowing you to disable this system in you customers diesel vehicles. AdBlue systems can be complex and costly to maintain. By reprogramming the ECU, Zentune disables the AdBlue System, removes associated dashboard lights, and prevents warning messages from appearing.

This service is especially beneficial for vehicles that consume large amounts of AdBlue, reducing maintenance costs and simplifying vehicle operation.

Before proceeding, check local regulations to ensure AdBlue removal is legally permitted in your area.

Inlet Manifold Swirl Flap Removal / Delete

Swirl flaps are small butterfly valves located within the inlet manifold of modern diesel and petrol engines. They play a crucial role in regulating the fuel to air ratio, enhancing emissions control, and generating better torque at low engine speeds. At light engine loads, the flaps close, creating a swirling effect in the air entering the combustion chamber. This swirling action improves combustion efficiency, leading to better emissions and increased torque. Once the engine reaches 2000 rpm, the flaps generally open fully, having minimal impact on engine performance and emissions.

Zentunes Inlet Manifold Swirl Flap Removal Service is designed to help workshops address these problems and improve vehicle performance.

The Process commences with the design and depending on the complexity, the manifold is either unbolted and the flaps physically removed, or the electronic actuator is disabled while leaving the flaps in place. This process prevents potential mechanical failure, reduces carbon build-up, and improves engine efficiency.

Speed Limiter Removal

Many vehicles come with factory set speed limiters that restrict top speeds. Zentune offers a Speed Limiter Removal Service for workshops and mechanics, allowing them to adjust or remove these limiters through ECU Remapping.

This service is available for most vehicles, and in cases where complex speed limiters are present, Zentune provides a specialized service at its Sydney HQ. Workshops can also offer speed limiter adjustments or applications, with fleet discounts available.

By incorporating these ECU Remapping solutions from Zentune, workshops and mechanics can offer their customers a wide range of performance enhancements and vehicle optimizations, ensuring improved satisfaction and vehicle performance
