Oh and was going to ask if you thought the DP's or suspension played a role in the time? I think you said that was new and your previous time was about 2 tenths slower. I also think you said your MPH was slower but your ET was 2 tenths faster. How did the 1/8 look? From what I hear the DP's give some low end grunt so maybe you picked it up in the 60 or 1/8th?

Yeah, everyone at Carlisle thought of you Mike, when looking at the Mustang owner washing his car in the rain. All we need next was someone in surgical gloves, that would of been icing on the cake.
Rich's car, I want on the scales. I think him not having heated/cooled, massage seats, no sunroof, no rear sunshade, he had a 100-200 lbs on most of us. Very proud of you buddy. Yeah the prepped sometimes at Beaver sucks big time. I love the pro tree!

I ran a 12.42 with just tune & 3bar...went to catless DP'S, coilovers, and better tires for a 12.40 on a real hot day (2300 da). Received race tune and went 12.34.Scott4957 said:Oh and was going to ask if you thought the DP's or suspension played a role in the time?

Decided to go catted Livernois downpipes, Corsa catback, and hard pipes and that scored me this 12.25 at over 2 mph slower. My previous 1/8th was 7.9.

Race tune? Are you running 100 octane or something?
Thanks guys.
Will be at CAD next week to get this thing turned up I hope. These runs I had zero KR, 1800+ fuel rail pressure, and only 13.8 lbs of boost...there's plenty more left in the FreakSHO!
I run a mix of e/85...17-20% I'd put it at.

First off, fantastic times. Great job! I see even better ones in your future.
It sounds like you are getting better than normal results due to a few factors:
- car maybe a little lighter than heavier optioned models
- you have track experience
- a custom tune by LMS that also accounts for an ethanol mix
Is that correct?

The car put down average numbers until I started mixing corn. Which just so happened to be right around the time I started getting used to launching the car good and getting some good 60' results. Every time it has went quicker it's been in direct correlation with the 60'.

I have been pondering this, but still don't understand.
Can we just mix ethanol into our tank and do nothing with the tune? I didn't think our cars were flex fuel capable. Can I just add E85 and go faster?
Are you data logging to make sure all is ok?
I don't think that any off the shelf Livernois tunes are ethanol friendly. Am I wrong?

There is a difference between adding a few gallons of e85 and running all e85 and being considered flex fuel vehicles....running e20-e30 is alot different
Can you add some e85 and do nothing to the tune? Sure will the tune be slightly out of whack and less than ideal? Absolutely..but will there be symptoms felt by the driver? Probably not due to the ecu's compensations provided they dont exceed thresholds.
Will e85 make you faster, maybe...but it will add some knock resistance at the expense of fuel economy and allow for additional knock sensor spark advance to programmed limits

The out of whack, less than ideal tune seems to net a .5 reduction in ET.
I know that you need considerably more fuel volume with ethanol. I wonder what percent is possible for the car to adapt to since it's not a flex fuel motor.
OP, are you on a v8, 9, 10, or other tune?

You obviously are not a tuner...just because a car can be quicker doesnt mean it's properly tuned....I explained above why there can be more power
The car is not adapting at all when higher ethanol fuel is used...you are relying on the primary 02 sensors to adjust fuel delivery and that is a tune that is out of whack
And its about 25% where the ecu limits short term fuel trim adjustment
SHOdded said:25% STFT+LTFT, right? And I believe the fuel door sticker on 2010-12 says E10, on 2013+ it is E15 max?
Yeah but the two arent related...25-30 % is a typical stft max for the purposes of component failure...wouldnt want your 02's adding 80%
In other cars and software 25% seems to be the norm
I'm just wondering how much ethanol is possible without a problem?
When I said the car was "adapting" I was referring to the ECU reading the O2 sensors and adjusting the fuel requirement to "adapt" to the ethanol.
FWIW, my 2013 says E10 ok, but not E20-E85. SHO, you may be correct as that leaves a gray area between 10 and 20.
Another number to consider is that E85 requires roughly 35% more total fuel than E10 to make equal power. Less additional fuel would be required at lower ethanol amounts. However, if you're also going to make more power, then you need more fuel beyond the 35%.
The part I'm not understanding still is how the car is running that much quicker without a tune to account for the ethanol. An off the shelf tune shouldn't be getting substantial timing retard to begin with, so I wouldn't think that the ethanol would be eliminating a timing reduction and I wouldn't think that it would benefit much from the cooling effect since it shouldn't be detonating to begin with. I am not saying there wouldn't be any gain, but these results are pretty amazing.

Plenty of people running e20-e30 with no "detectable" symptoms
No gray area...oem and livernois say they dont like more E
You are correct, an off the shelf tune shouldnt be getting that much timing retard...the ethanol isnt eliminating the timing retard but rather allowing timing advance as allowed by the knock sensor there is a difference
Riches results are not typical so i wouldnt beat yourself up over it. Its unique to say the least
My friends 2015 sho with 2 gals of e85 mixed with 5 gals of 93e0 ran 13.5@105. Last night he went again but with 92e10 and ran the best of 13.9@100, it was a bit hotter but cant be that big of a difference as far as weather goes. E85 made a big difference and he could feel it.

I really appreciate all of the input. Very interesting that people are gaining this much with ethanol.
What is the correct way to calculate the ethanol mix?
Is it correct to add the ethanol percentages and then divide by the gallons?
So, using the above numbers...85 + 85 + 0 + 0 + 0 + 0 + 0 = 170. 170/7 = 24.29% ethanol. Is that correct?
