BM3 Log update with some e85
Ambient temp: 85 degrees Fahrenheit Elevation: 500-750ft above sea level Note: most of these were done using manual and then flooring it (not kickdown) while 2.5K-3K RPM. I also tested the gas and ethanol at the pump. Tune: Stage 1 - 91 Octane Gas: Shell 93 Nitro+ https://www.bootmod3.net/log?id=5ed0...0b4346a423b18e https://www.bootmod3.net/log?id=5ed0...729b5a08bd5c74 with kickdown and auto D3: https://www.bootmod3.net/log?id=5ed0...90c655ccf3cdb0 Tune: Stage 1 - 91 Octane Gas: ~e26 (26% ethanol) Notes: timing looks better but not as good as expected https://www.bootmod3.net/log?id=5ed0...729b5a8ce288e9 -starting to look better: https://www.bootmod3.net/log?id=5ed0...729b5a8ce288ef Tune: Stage 1 - 93 Octane Gas: ~e26 (26% ethanol) Notes: looks better! HPFP doesn't seem to have any issue and hitting closer to target boost, thoughts? https://www.bootmod3.net/log?id=5ed0...729b5a08bd5ce9 https://www.bootmod3.net/log?id=5ed0...0b434621ac4c71 https://www.bootmod3.net/log?id=5ed0...90c655ccf3ce23 Verdict: I continue to love e85 My old N55 motor ran 100% e85 for 60K miles. I'm going to test e40 on the e30 map next. Last edited by sd306; 05-28-2020 at 10:06 PM.. |

Looks like U.S. gas sucks IMO... I don’t think the EU has this problem and needs E.
The E blend (did you test the E85 content?) seems to work very well, how does it feel? Also I’m on my phone but see 0 knock with E blend

Yes, I tested the gas at the pump. Their 93 was 10% ethanol and their e85 was 85% ethanol. Everytime i've tested their gas and ethanol it's always spot on! -Updated the original post to say i actually tested the gas. |

Case in point why you need to test... just tested this “E85” and clearly not E85... it’s E70

Yeah, I learned long ago to never trust it. Get weird looks at the gas station each time lol. I'm still wanting this:

Right, but the little test tube does the same test. It's much easier than testing it in a little tube each time. Also, i'll do a log review after using a bit of gas before continuing to do pulls.

Is that product called "Boost Donkey"? Edit- from the still photo I couldn't tell. Watched the video and see it was monkey. I know test cars are referred to as mules sometimes, so I thought the kit might have been called boost donkey, which would have been hilarious. I guess boost monkey works too as you monkey around with your mixture. Alright, enough of this monkey business. Just got a craving for bananas. Gotta go.....

I got word back from PTF. They recommended going to a lower tune or increase octane. I sent them the stage 1 93 tune logs while running e25. We'll see what they say.
I also just filled up with e35. I'll take another log and see how the stage 1 93 tune does on it and may also test the stage 1 e30 tune

E35?! Yikes, stock can handle E25 max, I would say for any stage 1 due to boost increase to keep it around E20.

Going to load the e30 map and test. With my old car the HPFP could flow e60 stock with an upgraded LPFP. The stock S55 HPFP can run 100% e85 if I'm not mistaken.

Tune: BM3 Stage 1 - e30
Fuel: e35 Elevation: 500-750ft above sea level Note: Done using manual (no kickdown) from 2.5k-3K rpm. AFR around 13. Looks good to me. Thoughts? https://www.bootmod3.net/log?id=5ed2...0b4312bfa1217e Last edited by sd306; 05-30-2020 at 02:42 PM.. |
