Stage 2 91 Logs

Hello All,

Please take a look at my BM3 Stage 2 91 logs and let me know your thoughts.

Right now I'm running non ethanol, pure 91 octane. The car runs noticeably better, but it appears I'm still getting timing corrections? New set of NGK spark plugs as well.

Should I try the ACN91 Map? I'm in Colorado btw.

Do you have access to higher octane gas, or ethanol? If it were me I would throw in a couple gallons of E to clean up the timing corrections. Throttle position and boost looks good throughout the pull.

91 octane is the highest in this region. I do have access to e85, but since switching to non ethanol.. the car just runs better. Iíll keep it in mind regarding adding more ethanol.

Interesting. What is your opinion on mixing 91 with e85 vs 110 race gas. Will look into ACN91 as well.

I would immediately switch or add octane tbh..

Adding e85 is fine, adding a gallon or two per tank will likely take care of the problem. 110 race gas is fine too if it's unleaded.

It's better but it's not right.. iats are a bit high too. Whats the temp there? What plugs?

Actually.. can you do start the log at just after 2000rpm and instead of letting off, can you let it shift to 4th gear and then let off after running through 4th?

Yeah, your fuel is just really bad. I'd add a gallon of e85.

Thanks for reviewing. I have a tu hpfp. I might as well explore E30 or other maps if mixing ethanol is unavoidable.

It wouldn't hurt but adding a little e85 won't require any difficulty or math lol

You won't need to be on an E30, E40, etc map to allow for experimentation with ethanol. I use it when running my stage 2 93 octane or stage 2+ 93/95 octane maps. I put in 2 to 4 gallons of E when I fill up. Then every few fill ups I just use 93 octane. Then start over with E the next time. It's been working great for me.
