ADVANCED TUNING OPTIONS / LAMBDA Defeat Software
A lambda sensor normally will have a life of between 30,000 & 50,000 miles, but it is known that the lambda sensor can fail prematurely if it becomes clogged with carbon deposits, or is contaminated by lead from leaded petrol or silicone from an antifreeze leak or from a silicone sealer. As the sensor ages, it will become less accurate and slower with its readings. Eventually it will produce an unchanged signal or no signal at all. When this happens, the Check Engine Light may be displayed on the dash panel warning you of a fault, and the engine will experience drivability issues caused by an overly rich fuel mixture. Poor fuel economy, elevated CO and HC emissions, poor idle, and or including hesitation on acceleration are the normal symptoms. There are many problems relating to faulty or poor LAMBDA sensor readings, misfiring, stumbling, high emissions, and generally poor performance
Also beyond the issues noted above there are applications for race conditions where a sports cat or de-cat is fitted thus reducing the efficiency creating LAMBDA Efficiency error faults within the ECU and resulting in a loss of power, this threshold can be raised or completely removed. With a total de-cat system then this is applicable and where lambda defeat is essential to maintain optimum performance with no limp mode or CEL (Check Engine Light). It also can give you much more flexibility in tuning to optimise for a wide range of bolt on tuning parts.
Currently we can offer this service for all Bosch ECUs and some Siemens for example the MSD80 units as fitted to the new BMW 335i & 135i models. However we are always developing solutions for other vehicles so please email with your requirements.
