So I loaded my E30 tune for the first time today and filled up with E30. My local e85 station was testing at E80 so I loaded up about 5.5 gal to the rest 93 octane. I was at about quarter tank at fill up. How long did it take your cars to hit the fuel rail with the e30 ? I drove around had to be 30 mins with maybe a total of 15 miles maybe less. The car felt sluggish like it seemed less peppy then the 93 octane tune was. I held off from romping it. Is this a symptom of the fuel rail not getting the e30 blend yet or does it take a certain amount of time for all fueling to adjust accordingly?
I have switched a bunch from 93 to E30 to E85 to E30 etc. I use E30 now predominantly as its easy to mix quickly. I have a 2015 SHO non PP.
In the future for fuel calcs try Wallace racing. Easy to figure out. Google E85 Blend Calculator. Browser not an app. I am usually at E35ish as the tune will handle it according to AJP. Just dont read the lines. Put in what you have and it will work.
I usually do a KAM reset and then let it learn for days. I dont know how these guys tune then track then retune. My transmission burp from 1st to 2nd was learning related so it seems.
So to answer your question. Its not the fuel in the rail imho. Its the car learning the tune ?
The E30 tune should be heads and tails better than the 93. Night and day butt dyno feel. Especially 60 to 120.

Whose E30 tune do you have?

You need to go and an make a couple logs for Brad. He will adjust the tune, and it will come alive and you will say WTF!

Even if it feels like it's bogging right now ? I havnt heard back from him yet and I definately don't want to risk going full throttle yet . Driven about 40 miles maybe on the tank so far
I have an ethanol sensor and it typically has settled after filling up around 5-10km or so.

Yeah if it is a first revision it will be a soft tune to see what is happening with the car. He will ask for a third gear pull from 20 mph up to the top of 3rd gear with the shifter in "S". Then he will ask for a 1st - 3rd gear pull with traction off, from a stand still with the shifter in "S". If you can, I would have those logs ready.
Stock/OEM tunes will handle up to E18 or so without need for tuning. If you did not load an E30 tune right after you filled up, that might be why the SHO seems to be bogging.
If you DO have an E30 tune on, you could try a KAM reset by pulling the neg batt cable for 40+ minutes to force the PCM to relearn. Shouldn't normally have to do that, but can happen.

The logging part I knew cause I had to for his 93 octane tune , just wanted to make sure from everyone's experience if what I'm experiencing bog from gas not mixing fully or just a simple soft tune. Didn't want to go full wood until this was clear. Thanks man

Mine was soft as well, and then we got through a couple of revisions and she was riding! Worth the time and effort for unlock the power of E30.

Loaded the tune at the gas pump before pumping it in but didn't start the car before pumping the fuel
I also always add the E product in first then put the regular fuel on top of it in the tank. It helps mix the fuel.

That's what I did . about 5.5 gals E80 first before the 93
Bottom line is it doesn't take long to mix and make it up the fuel rails. Maybe a few minutes. Been running E30 as well.
UPDATE : so I have a 25 mile commute to work so this morning the car felt sluggish still but the last 5 miles it started to feel better . I decided to do a KAM reset for the 2nd time this evening cause maybe the e30 did finally reach the rails . well SMOOTH AS GLASS. I think I was right that it was bogging and hesistant even after doing a KAM reset 10 miles after filling up because it needed to mix and hit the rails. So now that she's smooth she's ready for data logging . Smooth but the tune is soft for sure power is stock or less then stock power level . Can't wait to get the tune finalized. Thanks to everyone for your replies and help , the forum is the best go to for all of us ! 70 miles on the tank and gas milege is the same as 93 octane go figure LOL
Yeah once those long term fuel trims get settled in they can take a little bit to get back to normal. KAM reset after almost any flash is a must to me!

I have only KAM reset my car once......I wonder.....
Sorry, this is pretty old post and knowing Brad, I'm sure you've got this issue nipped in the bud, BUT....you might want to check your stations "E" content of their E85. I checked my local stations content with a [cheap] test kit and found it to be closer to E72, than E85. They're by law allowed to go as low as E70.
I mention this because (as I understand it), an E30 mix needs a richer mixture. So if your tune is pushing more fuel, but you're not running enough "E" to warrant the amount of fuel your pushing, that could cause bogging or sluggishness.
