DPF Delete Software Remapping

DPF Delete Software Remapping

DPF is an abbreviation for Diesel Particulate Filter on some French vehicles it is also known as a FAP filtre à particules

A DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with a functioning filter will emit no visible smoke from its exhaust pipe.

In addition to collecting the particulate, a method must exist to clean the filter. Some filters are single-use (disposable), while others are designed to burn off the accumulated particulate, either through the use of a catalyst (passive), or through an active technology, such as a fuel burner which heats the filter to soot combustion temperatures, through engine modifications (the engine is set to run a certain specific way when the filter load reaches a pre-determined level, either to heat the exhaust gases, or to produce high amounts of NOx, which will oxidize the particulates at relatively low temperatures), or through other methods. This is known as “filter regeneration”.

Regeneration is the process of removing the accumulated soot from the filter. This is done either passively (from the engine’s exhaust heat in normal operation or by adding a catalyst to the filter) or actively introducing very high heat into the exhaust system.

When the filter becomes clogged a regeneration is needed. Regeneration consists of periodically burning off the particles accumulated in the particle filter.

Regeneration of the particle filter :

  • Regeneration occurs naturally if the temperature of the exhaust gases is sufficient
  • Regeneration is instigated by the injection ECU if the temperature of the exhaust gases is sufficient but the particle filter is clogged
  • Some vehicles inject more fuel in the regeneration process others use Eolys, a cerine based composite which is add to the fuel to lower the particle combustion temperature

Occasionally the filter cannot regenerate on its own and a forced regeneration is required via a dealer level diagnostic tool. If a filter is to heavily loaded a replacement filter must be fitted if not temperatures can get very high and could cause a fire.

Replacement of a DPF including several hours labour can be an expensive procedure . We at KC systems can designed a cost effective solution .

The DPF can be removed from the car, cut out of the exhaust system , sensors left unplugged (no sensors at all) or left in the exhaust . we then program your ecu to ignore all the DPF signals & required data , leaving you with a perfectly running DPF free vehicle
No more regeneration , no more black smoke . No more DPF check lights ondashboard !!!

PLEASE NOTE :

We specialise in DPF delete remapping only . We do not get involved in the mechanical removal of the DPF itself . This procedure in normally carried out by the customers own mechanic/garage .
Once removed , we can then proceed with the DPF delete remap .

BEFORE WE REMAP YOUR ECU FOR A DPF DELETE , YOU WILL BE ASKED TO SIGN A DISCLAIMER STATING THAT YOU FULLY UNDERSTAND THE PROCESS AND THE POSSIBLE OUTCOME !
