Hot start repair
Some vehicles may suffer from hot start issues, where the engine cranks for too long, starts reluctantly or behaves irregularly once warm. By adjusting the software, we correct unsuitable start map settings and ensure quick, smooth and reliable starts even with a warmed-up engine.
This modification does not solve issues caused by a faulty fuel pump – in such cases, a mechanical repair is required.
EGR valve disable
The EGR valve (exhaust gas recirculation) is designed to reduce emissions, but in practice it often causes intake contamination, power fluctuations or a higher failure rate. By disabling the EGR, the engine runs cleaner, throttle response improves and the risk of carbon buildup is reduced.
Disabling the EGR may lead to faster DPF clogging and increased emissions.
DPF disable
Are you struggling with a clogged diesel particulate filter, frequent regenerations, loss of power or increasing fuel consumption? If the cost of DPF repair or replacement is unreasonably high, we offer a software DPF disable that removes these issues and restores reliable, smooth engine operation.
Removing or disabling the DPF makes the vehicle technically unfit for road use and it will not pass a roadworthiness inspection.
AdBlue disable
Do you want to reduce operating costs, are you tired of constantly refilling AdBlue, or are you dealing with repeated failures of this system? By disabling AdBlue injection, we remove these concerns and help you avoid often unreasonable and repeated repair costs that can easily reach thousands.
Readiness calibration of emission monitors
Readiness calibration adjusts the status of individual OBD monitors so that diagnostic tests can be completed correctly. In practice, it can help bypass emissions inspection issues, for example when the vehicle has a fault or a modified emissions system.
This modification interferes with the vehicle's emission diagnostic systems and may conflict with legal requirements. A vehicle with this modification may not meet the conditions for road use.
Technical inspection guarantee
With our modifications, we guarantee you will not have any problems at the technical inspection.
Approval by the Ministry of Transport
For selected modifications we also offer solutions prepared for legislative extensions.
