An even 5 puts you @22% which is where I've been for a while.I've read a lot of research and 20% seems to be the threshold, less than that doesn't seem to have any benefit and then the benefit increases until E-30-40ish. Of course as the blend goes up rail pressure drops so it becomes a balancing act. When filling up, I'd suggest corn first then 93 so it mixes properly.

What I noticed right away is the car was smoother and seemed to shift harder, not sure how that happened. Another thing I noticed now that it got colder out for the last few days(55-60f) the car seems to have a hicup in 2nd around 5200rpm but once its warmer 65+f it is not present and the car accelerates good. This only happens under WOT. I am not sure if it has to do with extra boost or something when its colder. It feels like the car stops accelerating for 1 second and after that point its back to normal. I will log this weekend and have torrie see if 3 gallons is too much for my fuel pump, if he thinks I can add more I might try 4.5 gallons.Sent from my SM-N910V using Tapatalk

Quote from: FoMoCoSHO on May 06, 2016, 03:55:08 PMI am familiar with the events you guys are talking about. My car does it as well but not when sport mode is activated which leads me to believe it is a TC event that I miss the blink or it doesn't always blink. With the kind of power some of us are running I think the tires can momentarily break loose in unexpected environments. An example of this is the 25 MPH WOT downshift to first. With sport mode disabled, the car will cut out sometimes with a light and sometimes without. In sport mode, it doesn't happen at all.I have seen shutdowns with the old car due to too much E and very low temps but those also came with a +7 KR so I assumed I was out of fuel. These other events I never see any KR activity so I just drive in sport mode all the time. Even in sport mode I see TC/ESC blinks where I wouldn't expect them. I also have times where I feel a wheel break loose with no light.If you guys log it, make sure you log torque source so we can see where the request comes from.When mixing E-85 i never beat on the car until STFT's return to normal.
