This lambda simulator is designed to support individuals who have modified their car's exhaust system by removing the catalytic converter or altering the centre section. It mimics the signals expected by the ECU from the rear-most lambda sensor, as if it were reading exhaust gas that has passed through a catalytic converter. This helps prevent unwanted engine management codes that could potentially trigger the EML (Engine Management Light), thus allowing for more accurate monitoring of the engine's performance.By replacing the sensor entirely, this unit enables you to utilise the OEM bung for fitting a wideband sensor, offering additional reassurance and monitoring capabilities, especially for turbocharged or supercharged engines, without the need for expensive welding. The unit can be easily wired within the ECU box or in the passenger seat area and includes comprehensive, full-colour instructions for straightforward installation. While DIY installation is feasible, we recommend professional installation if you're not experienced with electrical systems. This is for off-road use only, to comply with UK regulations Please note this is only for the IS200 with a 1G-FE engine, IS300's will NOT work.
