Hey guys,

My n55 is from Canada and has a Eurocharged tune optimized for 94 octane. I'm in Tennessee and we only have 93 so I've been mixing in about 3 gallons of e85. According to my rough calculations, regardless of winter or summer blend, this should keep me above 94 octane and below e30. Is this okay or should I get a different tune? I'm happy with the way it drives/runs with this tune.

Thanks!

I'm not as familiar with the 94 octane they have up in Canada but I think it is ethanol free. I would not be worried about mixing a couple gallons of ethanol to each tank. I just wouldn't do more than 3. I assume you have no way of logging the car?

You're probably just fine running the 93 octane honestly. There may be some timing corrections and I wouldn't assume that they are selling really hot tunes.

Correct, no way of logging it. I think you’re probably right that I would be okay on 93 but to be on the safe side I figured this should get me to at least 94 octane without exceeding e30 (seems like every healthy car can do e30 on the stock pump).

Thanks for the reply!

Do some logging and research but out fueling in Canada is absolute garbage.

Our 91 Octane is worse than your 91 ACN. I run 91 ACN maps on 94 Octane since I fear running more aggressive maps.

With 93 American Octane you should be fine!

This is good info, i appreciate it! I wonder f the rating system is different where your 94 is roughly equal to our 93.

Regardless it seems like especially if I’m mixing in a few gallons of e85 I should have plenty of octane for my tune without worry of timing corrections. Thank you!
