Which octane for custom tune?
I have access to 95, 97, 98 and 100 octane petrol. The octane number changes depending on the petrol station you go. When I had my bike dyno tuned last time, I had it done with 100 octane as that was what the tuner recommended. The problem is sometimes when we go for rides outside the city it is difficult to find 100 octane, instead I fill up with 95 or 97 octane.
I've been driving turbo cars and they are very octane sensitive especially on high boost levels but bike engines seem to be less fragile even with a custom map. Maybe because bike engines are louder but I don't hear any pinging/knocking when I use lower octane.
Do you think it's better to have the bike tuned with lowest octane (95) as a safety measure? Will using lower octane hurt the bike if the bike is tuned for higher octane? I prefer to have the bike tuned for highest octane because I have access to 100 octane most of the time but also don't want to hurt my baby during rides outside the city where I am much harder on the throttle.
