No physical modifications are required. The remapping adjusts fuel injection maps, turbo boost pressure, ignition timing, and torque limiters to unlock the engine's full potential. Typical gains range from 20-40% additional horsepower and torque depending on the engine type. Stage 1 is safe for the engine when performed correctly, as it stays within the mechanical tolerances of stock components. Suitable for all turbocharged diesel and petrol engines. The original file can be restored at any time. - Type: Performance optimization - Typical gains: +20-40% power and torque - Hardware required: None (stock hardware) - Supported engines: Turbocharged diesel and petrol - Reversible: Yes, original file can be restored - Delivery: under a minute via automated processing ### DPF Off - Diesel Particulate Filter Removal DPF Off is a software solution that disables the Diesel Particulate Filter regeneration and monitoring in the ECU. This service is intended for vehicles where the DPF has been physically removed (competition/off-road use only). The modification disables DPF regeneration cycles, DPF differential pressure sensor monitoring, and associated DTC codes. This prevents limp mode and dashboard warning lights related to DPF issues. The software modification addresses all DPF-related maps including soot loading models, regeneration temperature targets, and ash content calculations. - Type: Emission system software modification - Purpose: Disable DPF regeneration and monitoring - Warning: For off-road/competition use only. Removing the DPF is illegal on public roads in most jurisdictions. - Supported: All diesel vehicles equipped with DPF - Delivery: under a minute via automated processing ### EGR Off - Exhaust Gas Recirculation Removal EGR Off disables the Exhaust Gas Recirculation valve control and monitoring in the ECU software. The EGR system recirculates exhaust gases back into the intake to reduce NOx emissions, but over time it causes carbon buildup in the intake manifold and on intake valves. Disabling EGR improves engine reliability, reduces intake contamination, and can slightly improve throttle response and fuel economy. The software modification closes the EGR valve permanently and disables associated error codes and diagnostic monitors. This is commonly combined with Stage 1 tuning for optimal results. - Type: Emission system software modification - Purpose: Disable EGR valve operation and monitoring - Benefits: Reduced carbon buildup, improved reliability, slightly better throttle response - Supported: All diesel vehicles equipped with EGR - Delivery: under a minute via automated processing ### AdBlue Off - SCR/AdBlue System Removal AdBlue Off disables the Selective Catalytic Reduction (SCR) system and AdBlue (DEF) injection in the ECU software. This service addresses AdBlue dosing unit control, NOx sensor monitoring, SCR catalyst efficiency monitoring, and all associated diagnostic trouble codes. It is intended for vehicles where the AdBlue system has malfunctioned or for competition/off-road use. The modification prevents limp mode triggered by AdBlue level warnings, quality sensors, and NOx catalyst efficiency codes. - Type: Emission system software modification - Purpose: Disable AdBlue/SCR system operation and monitoring - Warning: For off-road/competition use only. Disabling AdBlue is illegal on public roads in most jurisdictions. - Supported: All diesel vehicles equipped with SCR/AdBlue (Euro 5/6) - Delivery: under a minute via automated processing ### E85 - Bioethanol Conversion E85 conversion is an ECU software modification that adapts the engine's fuel system calibration to run on E85 bioethanol fuel (85% ethanol, 15% gasoline). The remapping adjusts fuel injector duty cycles (typically +30-40% more fuel), ignition timing optimization for ethanol's higher octane rating, cold start enrichment maps, and lambda/AFR targets. E85 offers a higher octane rating (~105 RON) allowing for more aggressive ignition timing and potentially more boost on turbocharged engines. This results in cleaner combustion, reduced carbon buildup, and often noticeable performance gains. The conversion is suitable for most modern petrol engines with compatible fuel system components (lines, pump, injectors). - Type: Fuel system calibration - Purpose: Adapt ECU for E85 bioethanol fuel - Benefits: Higher octane rating, cleaner combustion, potential performance gains, lower fuel cost - Requirements: Compatible fuel lines, fuel pump, and injectors - Supported: Most modern turbocharged petrol engines - Delivery: under a minute via automated processing
