O₂ Sensor Delete & Decat Services
At Inverness Tuning, we specialise in professional O₂ sensor delete (lambda delete) and decat services for cars, vans, and performance vehicles across the Highlands and beyond. Whether you’re chasing more power, improved reliability, or simply want to optimise your exhaust system for off-road or motorsport use, our expert ECU remapping and tuning services deliver proven results.
Modern vehicles use oxygen (O₂) sensors and catalytic converters to monitor and manage exhaust emissions. For motorsport and off-road applications, an O₂ sensor delete (sometimes called lambda delete) disables post-cat sensor monitoring in the ECU software, while a decat removes the catalytic converter restriction entirely. This allows the exhaust to flow more freely and prevents unwanted warning lights or limp modes after hardware changes.
A professionally carried-out O₂ sensor delete (lambda delete) and decat service can transform the way your vehicle performs. By removing restrictive catalytic converters and disabling redundant post-cat O₂ sensors in the ECU, exhaust gases flow far more freely, resulting in increased horsepower and torque, sharper throttle response, faster turbo spool and improved boost efficiency. Proper ECU coding also prevents unwanted check-engine lights or limp mode after exhaust modifications, ensuring your car runs smoothly and reliably. For motorsport and off-road vehicles, an O₂ delete and decat can reduce exhaust gas temperatures, improve fuel efficiency under load and extend engine longevity, all while unlocking the full potential of your performance upgrades.
At Inverness Tuning, we use state-of-the-art ECU tuning tools and genuine software solutions to carry out safe, reliable O₂ sensor deletes and decats. Unlike generic files, our calibrations are built in-house for your specific make, model, engine code, and modifications.
