Mine had its first MOT this year and was very close to the limit, I wouldn't have the first idea how to find a friendly tester. Has anyone tried this? Curious as my first MOT is coming up shortly. I've started using 95 RON map a bit more often on short drives around town due to the reduced throttle response and car seems quieter which can be a pro at times. I assume this Map is just pretty much how the car would be standard before all the tinkering and I'm not doing any harm using this Map? Or am I miles off on my understanding?🙈🙈 Share this post Link to post Share on other sites
Kaltorak 111 Report post Posted December 23, 2018 The 95 map will pull timing to avoid the increased potential for knock with a lower octain fuel. However I don't know exactly what impact this will have on emissions. Share this post Link to post Share on other sites
