Custom software · 8 options
Custom software options for this engine
Legend Tuned functions suitable for this engine, which can be applied in the same session as Stage software or on their own.
Emission Systems
Emission system solutions for track and motorsport projects.
- DPF/FAP Delete A motorsport-focused software solution for the faults, power loss and limp mode caused by a clogged diesel particulate filter (DPF/FAP).
- EGR Delete A software solution for the smoke, power loss and check-engine light caused by a carboned-up, failing EGR valve.
- AdBlue/SCR Delete A software solution to the no-start countdown triggered by faults in the AdBlue pump, injector, heater and NOx sensor.
- NOx Sensor Delete Software that addresses the check-engine light, power restriction and AdBlue warnings caused by faulty NOx sensors.
Legal notice: Software for emission systems (catalytic converter, DPF/FAP, OPF, EGR, AdBlue/SCR, etc.) is intended solely for track / motorsport and closed-course use. Driving vehicles with these systems disabled on public roads, and presenting them for TÜVTÜRK inspection, may be against regulations. On request, the original software can be restored.
Driving & Sound Effects
Make yourself heard and be first off the line.
Fault & Function Solutions
Permanent software fixes for annoying faults.
- Fault Code Deactivation Software that permanently disables unnecessary fault codes in the ECU for systems that have been removed or are no longer used.
- Permanent Start-Stop Delete A solution that permanently disables the start-stop system that switches itself on at every start, or makes it remember your last setting.
- MAF/Air Flow Meter Delete Software that lets the ECU run on a calculated air model instead of a faulty or problematic MAF (mass air flow) sensor.
Stage 2 hardware, peace of mind and process
Stage 2 requirements
Stage 2 ready with the Custom Sport Filter Kit
At Stage 2, the engine's breathing is freed up with hardware, and the software is written to match that hardware. The target for this engine is 160 HP / 400 Nm.
- Air intakeThe made-to-measure Legend Custom Sport Filter Kit or an intake suited to the car.
- Intercooler & boostA vehicle-specific intercooler / blow-off valve to keep temperatures stable under sustained load.
- Silicone boost hosesHoses and pipes that withstand the higher pressure.
- Health checkIgnition, fuel system and clutch checked for this power level; the job takes ~4–8 hours (depending on parts fitted).
Included every time
Power with peace of mind
- Original software backup — the factory software is read and archived before the job.
- Reversal — the car can be returned to its original software whenever you ask.
- Datalog check — boost pressure, ignition and air/fuel ratio are recorded and checked on a road test.
- Vehicle-specific calibration — not an off-the-shelf file; tuned to the engine, hardware and fuel quality.
- Pre-tune diagnostics — fault memory is read and engine health is checked before the software.
