DPF, EGR and AdBlue (SCR) are diesel emissions systems, each managed by ECU software. An "off" solution modifies that software. These solutions are provided for legally permitted off-road, motorsport and diagnostic use only.
DPF (Diesel Particulate Filter)
The DPF traps soot from the exhaust and periodically burns it off (regeneration). A DPF solution adjusts the software that manages this process.
EGR (Exhaust Gas Recirculation)
EGR routes some exhaust gas back into the intake to lower combustion temperature and NOx. An EGR solution modifies the related ECU control and handles any diagnostic trouble codes cleanly.
AdBlue / SCR
SCR uses AdBlue fluid to convert NOx into harmless gases. An AdBlue solution adjusts the software managing the SCR system.
Legal note
Emissions-related modifications are restricted for road use in most jurisdictions. It is the customer's responsibility to comply with local road-traffic and emissions law. We implement these files cleanly, without leaving residual fault codes, for permitted scenarios.
