Is there anyone running 104 octane on the apr software? Wondering if there's a big power difference, or if it's not really worth it. Let me know

 

Static, just curious. Where would you be getting 104 octane fuel? Is that airplane fuel or something?
My understanding is octane rated fuel is recommended due to compression ratios. Have you done some motor work increasing your C/R?
Just getting ethanol free mid grade gas is a challenge here. Only sold as "marine" fuel at 30-50 cents more a gallon.

 

I'm pretty sure it's racing fuel, you could run it as a program in the apr ecu, but it is expensive

Unless you are running a tune for 104 octane fuel you are not going to gain anything from it, in fact if the tune is for pump gas you will most likely see a decrease in power since the timing will not be advanced enough for it.

 

w/e you do, just make sure its unleaded. and to see any gains, you will have to adjust the program
