Yet again, we have another failing EGR system, this time on a 2009 Land Rover Freelander 2, 2.2 160bhp engine.
Although this engine in question done 83,000 miles, it was quite clogged up, and pulling out at junctions did take a delay or two.
Despite what everyone says, when an EGR system is severlly blocked, you can not just write a new map, with the egr system disabled, as it will remain stuck open and not shut. Hence you need to manually block these as well.
What is an EGR?
EGR” stands for exhaust gas recirculation. When engine combustion temperatures near 2500°F, the formation of smog-producing nitrogen oxides (NOx) increases. Exhaust, however, is mostly composed of carbon dioxide (CO2), which does not burn. The function of the EGR valve is to recirculate small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides.
Its this build up of carbon that promotes failure of these items. Add to that the cost to customers to is not cheap either.
Once the EGR is blanked off mechaincally we can then set about tuning it properly, with egr function deleted, written into the new map.
standard power output is 157bhp and 295lb ft.
Stage 1 power will be
200bhp and 369lb ft.
MPG is a massive improvement of 15% so far on like for like driving.
Again proving that the cost of the remap will be paid for within the year, subject annual mileage.
