Hey everyone,
So I run AJPturbo tune now on 93. Was thinking of runnign an e30 tune and maybe year around as the Sheetz that has it is close by and readily available.
The Sheetz however doesnt just have e85. It has a ethanol rated at 51%-83% and says 94 octane on the pump label. Was wondering for those that run e30, what mixture do you put in your tank? I know there are calculators on line but they arent very accurate, atleast the two I looked at.
I ran a 12.83 @ 106 last in early Nov and shooting for 12.5 or better. My 60' was 1.8 as well.
Those that run e30 or even e20, how do you like it and what mix do YOU use for your e30/e20 tune?
Thanks.
If you want maximum power for E30 you want to mix with 93 octane and E85. Most of the time pump e30 is mixed with 87 octane which lowers the octane rating just a hair. I don't personally run an E30 tune, but pretty sure I have heard people running 3.5 gallons of E85 and the rest 93 octane. Surely someone else will chime in here soon. Just thought I'd add what I have seen because there isn't any discussion on it just yet.
That calculator I sent you is very accurate...just enter 60% for the constant for the ethanol pump and 10% for your pump 93 and run your tank pretty low and fill with the mix that the calculator and you should be good to go

Brad, for the calculator you included, would I leave e85 octane at 105 or change to 94 since thats what the pump says on it? I dont think that matters for mixture for me but more for you as a tuner because it changes the overall octane.
Also, one of my buddies who drives an STI said if I run e30 and other high ethanol blend tunes that oil changes will need to be done at closer together because the ethanol is thnner and makes its way into the engine more easily. Is that true? I'd like to know if there are any extra maintenance involved with running e30 for prolonged periods.

I wouldn't worry about the displayed octane but yea you can enter 94 for the octane since that's what it says for your E85 pump blend...Although I'm not sure why they say it's so low...Could be really low quality E85 blend....Should be closer to 100....On your screenshot you are only showing a E% of 23% so change your pump gas or Ethanol amount to the mix shows 30% if that's what you want. It looks like since your E pump is maybe around 60% that you need 12 gallons of pump 93 and like 6 gallons of E60 to give an overall blend of E30 but that's just in my head.
I don't know if your buddy is correct..He may be I dunno..I don't know for fact that E30 is "thinner"....Oil analysis would be the only way to know if your oil is spent or still good...If you have a high quality oil and a sound engine I would still think a 5k oil interval is ok....Call amsoil and ask...I'd be curious what they say.
Fuzz or Brad, can you post a link to that calculator por favor?
I'm another VERY happy camper with my 93 tune from AJP, and have been considering walking down the path towards E30. Just on the fence with whether or not it will put me back in the land of forced torque reductions from the ECU, with the additional power.
Email Brad. He sent it to me via email. Its a spreadsheet that calculates inputs.
Those with an e30 AJP tune, do you have a datalog I can check out please? Thanks in advance!
So this Youtube vid has the F150 3.5TT motor in it. It does better on Premium gas and now we can see sorta how and why. This is done via dry erase examples and charts. The AJP E30 tune can get better gas mileage thats for sure.

Considering that premium fuel also gets the best detergent additives, even if you normally run 87, running 93 once in a while IS worthwhile, in my experience. The latest and greatest Shell fuels are a perfect example of that. I have recently liked Mobil fuels with Synergy, 87 has been great. Will have to try the 93 one of these days.

All top tier grades have to be treated with the same detergents. The difference is in the amount...there is more in premium.
With what we are learning about additives and LSPI that may or may not be a good thing.
As far as E85 vs 93, well, its not apples to apples because flex fuel "certified" doesn't mean it is tuned to E-85 strengths (Leaner wot AFR, more spark advance, lean burn at cruise, etc) not to mention full E85 can operate very efficiently at much higher compression ratios (ie 16:1) If an E-85 engine was built and tuned around these principles you would see more power at lower displacement and equal to or better MPGs than 93.
We can't do anything about our static compression ratios but we can alter our dynamic compression ratios with higher boost and cam timing. I'm hoping once we're done with the power tuning I can throw Brad some cash and work on some of the part throttle efficiency areas.
Would be interesting to see hiw long the injectors last without added detergents. Could be no difference at all ...

If tailpipes are any indicator, could be longer.
My disgusting caked tips are self cleaning now.
That at least is a good step forward!
I have ajp e30, and I run sheetz e85... mine does not say 94 octane though. It was 70% last winter. I have not checked it recently. I would send you a log, but my brother is borrowing the computer with my logs on it. If ajp has any of my logs he has permission to give them to you.

Attached a couple logs from track passes. I did spike the E30 blend with some 100octane race gas for track day although timing is maxxed out so i don't think it helped in my case. But keep that in mind when you see such negative knock values.

Do you have an aftermarket HPFP? You dont have throttle control for the shifts and your fuel pressure is perfect? Looks almost like a meth datalog. I thought e30 tunes were prone to fuel pressure hits because of the ethanol?
I see it runs lower boost around 12-13.
I subtracted times for 0-85 and they were around 8.7 seconds. My 93 tune is around 8.3-8.5.
I dont get why the e30 would be slower or even with a 93 tune. Should be a good half second faster.
Maybe its your elevation.

It s his elevation...his barometric pressure is only around 82 kpa I think so his boost is really around 14-15 I think...he has the wastegate mod to his intake so we did not need throttle control
Cars are much slower where he is...even upgraded turbo sho struggle to get into the 12's
Brad, his target boost shows 190 MPA which is like 13ish right?
Anyone, what is this wastegate mod? If it helps with fuel pressure, I would love to look into it.
Ive decided on some future plans for my car which entails, new intercooler (Matts design when its ready), bigger turbos and XDI HPFP and of course an AJP tune.
That with some e30, you think its an 11 second car Brad?

I don't think any of those bolt ons are necessary. Maybe an easier route though. Personally I prefer the road less traveled, just ask Brad, lol.
I think if Sparkie had better DA, lower IAT2's, all of her spark, and some traction on her last outing it may have been close. Turbos still had plenty of room for some more boost if necessary. A driver brain mod would be helpful as well, lol.
If we get down to the nitty gritty with the Lincoln I have the one and only boost actuated cutout courtesy of EcoPowerParts that will hopefully get me across the finish line.
