Mr B Posted March 19, 2023 Share Posted March 19, 2023 the fuel octane mapping of factory tune make no real difference really to MOT emission test (it all mainly ignition timing tables at higher rpm/boost and wider throttle positions).. good order cat and oxygen sensors and the JDM grey imports passed Euro 3 emissions pretty easily when all components present and in good order . One thing worth noting is MOT emission testing is harder for the tester to get a pass result as MOT body has very recently changed the setup so the emission result feeds directly to the system while your vehicle logged in for it's test and you only got a one chance run for the readings so ideally operator wants be sure vehicle nice & hot and no obvious likely issues prior to doing the test run as you can't do like before of nursing it through multi test runs until get a good enough reading manually input .
