Diesel Particulate Filter (DPF) Friendly |
|||||
 Many modern cars are vulnerable to DPF blockage, especially when they are subjected to driving conditions that are incompatible with automatic DPF regeneration.
For example, if the car is mainly driven in slow moving traffic or used for short journey commuting, where the engine is rarely subjected to the driving conditions necessary for effective DPF regeneration, a build up of particulates in the filter can occur, ultimately leading to blockage. The problem may be exasperated by overzealous engine remapping or crude ‘diesel tuning boxes’ which can increase the amount of unburned fuel entering the exhaust system in the form of particulates. The result is the inconvenience of frequent trips to the dealer for ‘forced regeneration’, which may be a chargeable job. The Select-A-Map ECU reduces the risk of DPF problems by allowing any increase in fuel to be governed by engine speed and load so that fuelling can be accurately controlled to reduce particulate emissions to a minimum. Uniquely, with 5 instantly switchable maps to choose from, it is also possible for the Select-A-Map ECU to be configured to automatically default to a standard or more DPF friendly map under normal driving conditions, allowing any of the enhanced performance maps to be selected only when needed. DPF RemovalAn additional plug-in emulation module is also available for use with the SELECT-A-MAP. This will appease the engine management system of most vehicles and prevent them from going into limp mode, if the DPF were to be removed. |
