OFT E85 from low to high altitude
 

In about a month I will be moving from St. Louis MO to Boulder CO. I am pretty excited as the mountains (mountain roads) will be quite literally in my backyard. Just a few hundred feet from where I will be living. It will be a good time to own an 86. As much as I am looking forward to the twisty mountain roads, I won't be looking forward to the significant power loss. Makes me want to go FI. But that's besides the point.

Now what i'm worried about is the altitude change. I'm currently running the E85 tune and there seems to be just a handful of E85 stations around town which I'm okay with. However I'm wondering if I should have anything to worry about when going from roughly 500' to 5000' above sealevel. Are the base tunes flexible enough to handle this?

Altitude is not an issue as we use MAF reference for load determination (like the stock tune). We have plenty of customers that live 5000+ feet above sea level.

Fantastic to hear! Thank you for such a quick reply

I live at ~4500ft and all my logs look solid on E85 with no tweaks to the OTS map :)

I'm at 6,500ft above sea level in Cheyenne, WY and running Shiv's OFT E85 Stg. 2 OTS map, everything looks perfect! Great tune all around.

I don't know how you guys live up there. Walking up a few flights of stairs in Denver winds me ;)

Pushing my gas pedal seems to really wind my engine too -- power loss at altitude sucks!

I'll be up there next week! on 91 though, not enough corn juice gas stations from vegas to cheyenne.

im located south of denver and we currently have a FRS/BRZ facebook group. https://www.facebook.com/groups/Coloradofrsbrzowners/ join up! we got some great owners and support

Thanks! Just joined. I'm really looking forward to meeting the 86 community in CO.
