Truck ECU File Tuning — Stage 1, AdBlue, DPF, EGR

Chiptuning and ECU remapping software for truck, lorry (HGV) and bus ECU files: upload the original file you read from the heavy vehicle's ECU; the ECU is identified from the file itself and only the operations that apply to your file are enabled. Below are the truck and bus brands, the heavy-duty ECU families and the operations with verified solutions in the library.

Operations

Operations available for truck ECUs

Only operations with a verified solution for this vehicle type in the library are listed.

Stage 1Typical gains in power and torque with a livelier throttle response.DPF OffRegeneration cycles and DPF fault codes are disabled in the software.EGR OffEGR valve control and related fault codes are switched off in the software.AdBlue / SCR OffAdBlue/SCR dosing and its related warning functions are switched off in the software.Full Emission OffDPF, EGR and AdBlue/SCR are switched off together in one file, in one job.Stage 2Advanced calibration matched to hardware upgrades such as exhaust or intercooler.DTC OffOnly the selected fault codes are removed; other diagnostic functions stay in place.Vmax OffThe factory speed limiter is removed in the software.Decat / Catalyst OffCatalyst monitoring and related fault codes are switched off in the software.Lambda / O2 OffLambda (O2) sensor monitoring and related fault codes are switched off in the software.TVA OffThrottle valve actuator (TVA) control and related fault codes are switched off in the software.Immo OffSoftware solution for immobiliser-related no-start problems.Torque Limiter OffFactory torque limitation maps are recalibrated in the software.Stage 3Calibration for extensive hardware changes such as a larger or hybrid turbocharger.Gearbox (TCU) CalibrationGearbox shift points and response are recalibrated.

Operations on emission systems are offered only for use permitted by local law (e.g. off-road / motorsport / export); responsibility lies with the user.
