o2 Delete
Looking to unleash your vehicle’s true performance potential in Blyth and the wider North East? JME Performance offers professional O2 delete (decat) services, designed to optimise your engine’s efficiency and deliver a more responsive driving experience. If you’ve installed a decat pipe or a high-flow exhaust system, our specialist ECU remapping ensures your vehicle runs flawlessly, free from common error codes and performance limitations.
What is an O2 Delete (Decat) and Why is it Needed?
Modern vehicles are equipped with catalytic converters to reduce harmful emissions. These converters are monitored by oxygen (O2) sensors, typically one before and one after the cat. When a catalytic converter is removed (decat) or replaced with a less restrictive performance part, the downstream O2 sensor often detects an efficiency issue, triggering an Engine Management Light (EML) on your dashboard and storing fault codes like P0420.
An O2 delete, or decat remap, involves carefully recalibrating your vehicle’s Engine Control Unit (ECU). Our expert tuners in Blyth will disable the function of this secondary lambda sensor, preventing unwanted warning lights and ensuring your engine operates optimally with the modified exhaust system. This process is crucial to avoid issues such as:
Persistent warning lights: Eliminates the EML caused by catalytic converter efficiency codes.
Reduced performance: Prevents your ECU from entering “limp mode” which limits power and throttle response.
Incorrect fuel delivery: Ensures your engine receives the correct air-fuel mixture, crucial for performance and longevity.
At JME Performance, we are committed to providing expert and responsible tuning services. Our O2 delete (decat) process involves:
Thorough Vehicle Assessment: We begin with a comprehensive diagnostic check of your vehicle to ensure its suitability for the modification and identify any pre-existing issues.
Professional Decat Installation: Our experienced technicians will expertly remove your catalytic converter and install a decat pipe, ensuring a perfect fit and seal.
Custom ECU Remapping (O2 Delete): This is the crucial step. We use advanced remapping tools and software to meticulously recalibrate your vehicle’s ECU. This involves:
Disabling the downstream O2 sensor’s monitoring function to prevent engine management lights.
Optimising fuel delivery and ignition timing to maximise performance gains from the improved exhaust flow.
Ensuring your engine runs efficiently and reliably with the decat in place.
Expert Advice: We provide clear and honest advice regarding the implications of decatting, including performance benefits and any potential considerations.
