Fuel grades?

[CivicHatchLife]

So I’ve been running 91 in my civic since owning it 2 years ago. And recently installed a ktuner a few weeks back. Made the jump to 94 at petro Canada and everything has been running excellent less “knocks” recorded on ktuner just curious if I need to adjust something in the settings or will it automatically read that I have a higher octane running threw the system?

Your ECU will always make the most of whatever tune you are using based on the available fuel quality. It is likely no changed are required but it really depends on what tune you are using. For example if you are using a 91 specific tune you would need to upgrade to a tune that will take advantage of the higher octane.
