[QUOTE="shiroitenshi, post: 1063334000, member: 27518"] Yes, vtec engines with knock sensor and knock board equipped ecu's can run ron95 without issues. For those suffering knock due to not using the above setup, retarding the statice Ignition by two degrees should do it without needing to retune. For those modified to higher compression, might need more retard since their ecu mapping is more aggresive, but this might increase engine temperature. By how much, I dunno since dependent on the compression you run.[COLOR="Silver"] [SIZE=1]---------- Post added at 08:39 PM ---------- 6 hour anti-bump limit - Previous post was at 08:33 PM ----------[/SIZE] [/COLOR]Of course, if you run custom ecu mapping, this is another story, and retarding your ignition is a sure way to reduce power, but it is a way you can run the engine with ron95. Already tried this when not all petrol stations carry 97 RON long ago [/QUOTE]
