This was, by far, the most informative video of E-85 I’ve seen to date.

Your channel is a big reason why I bought my first VW. Picked up my mk7 Golf R 2 weeks ago and feel confident in doing maintenance myself, with the help of your videos. Thanks from Australia.

Glad to see this 2.0t survive the dyno

I don't even own a VW, but this is one of my favorite youtube channels. Just so entertaining.

This was super informative. I’ve always been a bit leary of E85 but thought it did a good job of laying out the pros and cons.

Lol I didn't expect the larping joke. Excellent content! I sold my GTI but won't let my DAP subscription go.

Hell of a good video. Best explanation of E85/Flex Fuel complications I've yet seen on KZfaq.

I put an E85 tuner on my 97 BMW R1100 a few weeks ago and it has been working pretty well so far.

Happy thanksgiving Paul and DAP crew!

Not sure which is of greater value: The comedy and puns or the education in your videos.

Got a Kroger near me and like all Kroger's they're notorious for always having spot on ethanol content, almost always 85% and sometimes even higher. Biggest benefit to running E in a boosted application is how much more torque you make down low due to the inherit resistance to knock and the more aggressive timing you can put in it, giving you way quicker and aggressive spool that carries all the way through to the limiter. Filling up 2 5 gallon jugs at the pump to take to the track is extremely convenient, too. Once your car is dialed on E you'll never want to pump standard gas again unless it's you're daily.

Again, best content in the whole carssection. So Volkswagen FSI only needs the high pressure pump? Running a 3.6 here.

this video came out at a perfect time, i googled and watched yt videos for 8 hours yesterday

In Brazil we have Flex Fuel TSI models and they shows lots of high pressure pump and injectors problems with long term ethanol use.

Now I know why the crows won't GMO corn, it's for the car not for dinner.

Your videos are funny and informative I really appreciate all your efforts to help us VW/Audi guys

I've been running an E30 blend about 2 to 3 gallons with the rest 93 octane at fill up for over a year now with success. Mk7 GTI full bolt on GIAC stage 2 tune stock fuel pumps..

I wonder how many stopped watching at 2:50 and just went and put e85 in their car. lol Nice work on this one.

Paul you got the best VW enthusiast channel hands down. (Charles’ is pretty good too I guess lol)

As someone with a big turbo Mk7 Golf R (EFR7163) on a custom UM Flex Fuel tune: worth every penny. Smiles per gallon > miles per gallon.

I just finished watching the above video. The negative points made about ethanol are incorrect. 1. The energy content of ethanol versus gasoline in an internal combustion engine is irrelevant. Engine optimization is the key. Engines optimized to run on ethanol will perform equal to or better than the same engine optimized to run on gasoline. Additionally, there are many instances where ethanol-gasoline blends in a gasoline optimized engine will outperform the same engine running on ethanol-free gasoline. 2. Ethanol does not suck water out of the air, it absorbs water that it comes in direct contact with. More importantly, the video spokesman states that ethanol will continue to absorb more and more water the longer it sits there. This is incorrect. Ethanol has a limit to the amount of water that it will absorb, and that limit is actually quite low. 3. Ethanol does not eat fuel system components. Ethanol is compatible with more types of rubber, plastic, and metal than gasoline and aromatics. Viton rubber was invented by Dupont in the 1950s to mitigate the damage done to rubber by gasoline, tetraethyl lead, and ethylene bromide. Ethanol-gasoline blends were not used in North America in those years.

Thank you Paul and a Happy Thanksgiving! Your jokes crack me up every time! You and Charles are the Best VW techs on the East and I’m sure we all appreciate you guys for sharing all your hard work and information with us. Again Thank you and Happy Holidays!

Happy to see you guys embracing IE.

Super informative video man! Been watching you for years and recently moved to charlotte and realized thats where you’re located as well 😂 might be stopping by for that flex fuel kit soon 💯

Thank you, this is a great video. I knew a little about E85 but this video is really good. This might be something I plan on in the future for my 3.6 Corrado.

My first Evo 9 making 768 awhp had a 2.3 striker, 2200cc ID injectors, 3 fuel pumps, and ran e85. I had to have the tank full, and kept 10 gallons in the back seat. All of that I might have got about 180-200 miles. But it was very hard to stay out of boost ;)

Maybe the most info packed and well presented Dummies version of this info I've seen?

Love the part where you mentioned 'larping as a technician' and showed the clip from the Mastodon video in the background...lol

I had a full e85 mk7.5 gti with a cobb protune and it was a serious monster.

Love the content...from Wisconsin! Was that Charles I saw?

The term flex fuel should only be applied if the car has a content sensor and can run whatever base petrol fuel you want and everything in between full e85, including full e85. without switching maps. Very few offerings are reliable in that setup for VW's on a stock ECU. Also, you can have your car tuned(I do this for my customers) for cruising on any fuel type and get better MPG's if the tuner is knowledgeable, experienced, competent and detail savvy.

thank you great info

"Wildly educational award winning documentary Moonshiners" was priceless. LMFAO

Y'all should do e85 test with the mk5 fsi. I'm in Fayetteville NC and love to see y'all for that tune!

good video with good info! been runny flex fuel in my CTSV for a while now, one thing to note is the power difference between e85 and 93 octane will grow with more boost or upgrades as the 93 octane will become even more of a restriction with more boost.

No fuel system upgrades needed on 5.0s luckily! Runs so much better on E85

Thx so much for a great video packed full of great info! Your GTI is looking sweet!!

Happy thanksgiving Paul. Nice video👏👏

That answered all of my questions, thank you!

On a stock Audi RS3 for example, adding 1-1.5 gallons of E85 to a full tank of 93 octane absolutely adds some pep and you minimize any issues by only running an E20 blend per se. 👍💯

Lol @ Mr. Lahey falling down the stairs. RIP Jim Dunsworth. Always a pleasure to see a DAP vidja Paul!!! Nice dyno comparison too. You could've jumped the in tank pump and got rid of almost all the 93 into some buckets before pouring the race ethanol into the tank but whatevs... This vid cuts thru the BS and 'splains the pros and cons of running your car on corn, period. Thanks for the laughs as always dude!!👍🤙😎

E85 and E-blends do help make more power. Having dabbled around with tuning I have gotten decent gains in timing advance running different blends. Starting at e30 was able to advance timing 2deg without increasing knock over pump 93.

I recognize that dyno! lol..i'm from Winston. Cool vid btw, very very informative! I love at 2door mk7 gti, Happy Turkey Day Paul!

New camera be hittin' different

here in brazil we make ethanol out of the sugar cane, we have e100 at every station. All cars made for here are flex, even some ckd "produced" here like the bmw active flex f30s and g20s, land rovers, jaguars, mercedes.... But we never had a ea888 flex fuel from the factory, would be amazing if we could buy the car or buy oem parts to convert our mono fuel cars. Such a shame vw never made... fun fact: even koegnissegg made a ccx with a engine map to burn E100 when a costumer here bought a car at the 2010s!

I've been using that Lucas 3X Octane Boost + 91 non-ethanol his past summer in my old Mustang... and she likes it! I'm running a lot more timing with no problems.

Brilliant video Paul!

To run e85 on the MK7 all you need is the hpfp if you are using the stock is20 turbo when you switch to the is38 to run e85 you’ll need both hpfp and lpfp or mpi and lpfp. The hpfp upgrade only without lpfp on the is38 can run up to e50 blend which will max out fueling. MPI is the way to go if you’re going is38 or bigger turbo.

Happy Thanksgiving Shop Dap.

thanks for putting in the work on this video. this is a lot of info that some tuner bros will ignore and blow up their cars

I always loved how GTI's produce far more torque to power ratio and makes it feel so much powerful than what it is

I live in a place where I can only get 91 octane fuel, but we do have E85. Should I put a bit of E85 to bump the octane of the fuel when I fill up?

I've never watched this channel, I'm assuming it's mostly a German car channel but it's a video about corn and as someone who runs corn I thought I'd chip in what I know. On my LS3 Camaro SS, running e85 I gained 12whp and 9wtq but that was on a mix of e85 and 91 as my tank wasn't completely empty AND my injectors were maxed out with e85. Thankfully it was a flex-fuel tune so I can always switch back to 91 (no 93 in my area) when I know I'm not gonna be running it hard (say when I go on road trips or whatever) If curious my car was running non-catted Long tube headers, CAI, larger throttle body, and e85 so ALMOST full bolt ons making 429whp and 430wtq

This video is very high quality

Very, very rich information. Thank you

Really good info, Being from NY I never wanted to do E85 in my Z as it sits and i have heard a lot of people having issues with starting and it gelling up when it gets really cold.

the corn caucus has done such an excellent job with lobbyists that no one even realizes ethanol can be made from sugar cane from about a tenth of the agricultural land needed for corn.

Great video. Great explanation. Cheers!

Reflect tuning in Winston Salem NC, best tuner in NC for foreign cars💯🤝

Really enjoyed that video

I live in green bay Wisconsin and when he said Wisconsin I was definitely caught off guard 😂 definitely cold and snowy here though

Great job guys!

Amazing work!

In the time-lapse photo at 6:21-6:28, the ethanol is not sucking moisture from the air or even getting condensation running down the sides of the glass container. It appears to have been shaken up with water, as is seen later in the video.

I daily my mk7.5 R on full E85. It gets around 220-295 MPG depending on how I drive. Not bad. I have a few E85 stations near me too so not a hassle to get. I also run it on my 2010 Camaro ss and don’t have to switch tunes/maps if I run 91/E85. Wish COBB came out with their Flex-Fuel support for the MQB platform already 😩

nice video. If it was Charles, he would have make 5-6 videos out of this one video

To anyone with experience using e85. I just got a f250 and it is a flex fuel. I was just wondering how to properly transition from gas to e85 and I also heard you had to switch back to reg gas when you do a oil change to clean out the engine. I’ve heard stories of people Messing up their fuel lines and it causing misfires. Just don’t want to damage anything but would definitely want to try e85. Any info helps thanks.

I gotta say those are damn impressive numbers on an is20 and e55-e57 fuel. That IE tune seems to really be good. Is this still Beta?

Thanks for the detailed info. Do you know why in Europe they do not recommend Flexfuel for direct injected engines?

Love the video!

Been running EQT Stage 2 E85 time for some time now, no complaints at all other than fuel consumption being high 😓 as for power the E85 tune sure does hold power up top as compared to my 93 tune where it would fall on its face past 100mph

Great info and great video. I don't have e85 or even 93 octane where I live in eastern Canada, 91 at best. Because of this, when I was having my Subaru built I had them install an AEM Methanol/water injection system in it. The way it is set up, my tuner told me it tunes similar to 110 octane racing fuel. I'm running 35 psi with a Garrett GTX3582r gen II on my closed deck ej25 making 619 all-wheel hp. The methanol injection comes on at 10 psi and tapers up to full flow at 25 psi of boost. No idea what size jet they have in it.

Awesome video!!

for any car made before ethanol came out it can be a problem any steel gas tanks or metal fuel lines will need to be replaced with modern ethanol friendly ones even for modern cars made to run it if you plan on storing it say over the winter drain the ethanol out and replace it with gas it's better that way on the fuel system it can be a bit tough on the fuel system if left to set with ethanol for a few months . as long as the car is running and driving it's fine it's when it's left dormant for extended periods that it's a problem.

Very informative…thank you 👍

I admire your channel, but your content on this subject is very incomplete. The burn of ethanol is an exothermic chemical reaction followed by an endothermic one, which is the evaporation of water [by-product of ethanol burn] into vapor that absorbs heat inside the combustion chamber. C2H5OH + O2 = CO2 + H2O Therefore ethanol fuel can stand higher compression ratios and ignition advance. Ethanol maxed engines can stand a much higher level of turbo boost. That's why comparing both fuels back-to-back in the same engine won't show the whole picture. You also don't need those complex methanol injection systems - like in the BMW M4 - as water is embedded within the Ethanol molecules. Gasoline is only included in the mix to help the start under 13ºC; help the lubrication of the fuel pump; preserve the rubber hoses. Also ethanol is a oil solvent, therefore your have to change the engine oil more often due to the higher levels of contamination.

Holy crap! That's a big boost in power. I noticed Unitronic has some higher ethanol tunes. Too bad it absorbs water so fast though. I was thinking about the clutch prob too as even a stage 2 tune will stress it a bit. Good details and great info, thanks!

Totally want a tshirt! Prolly won’t make the switch to E85 anytime soon, but that is a cool shirt.

Great info... I'm full apr2 stock turbo gti... Been wondering if I could use a small % of e85 for spirited driving days.....

Richard Holdener has been seeing really good results dynoing with E85, both American V8's and Hondas. Should also check out the Malakas Motorsports guys, they're running VR6's on E85 (with gigantic injectors and 30psi boost)

when you ran the dyno pull on the 93 tune did the car have some kind of ethanol sensor at all? and if i know my stock fuel system can handle about 7-9 pounds of boost, do you think it can handle running e 85 with no fuel system upgrades? great video!

I need to know where those stations are around Charlotte. Having my Focus RS dyno tuned for E85 next week.

Well done! Thanks

Thank you so much 🙏

thumbs up for Mr. Lahey reference

I would argue that the "stock tune" on modern cars already corrects AFR using the O2 sensors and seeks optimal timing using knock sensors. To a point, the stock tune is an ethanol blend tune.

I just paid $2.99 for 88 octane E15. It works great in non-turbo Euro engines, or 1.8T that takes 87 stock. Best mix is 1-2 gallons of E85 in with your preferred gas. It's 105+ octane and burns cooler, the perfect "additive". although I do use 3-4 oz of 2-cycle oil in a tank too. Between the 2C and the E85 I NEVER buy Techron anymore, and my cars run like a bear on fire.

Hey brother, thank you so much for the video! It was very informative! I have an 01' Trans Am WS6. I was thinking of going flex fuel. Would my fuel lines be at risk of deteriorating?? If so, what fuel line would I need to get to make it work for my application?? Raleigh NC THANK YOU

How would you know if the ECU can be set for flex fuel operation? I know that there are add ons that do monitor ethanol content and will compensate for the variations. They're rather pricey though but they allow a wide range of fuels to be used.

Is the new high pressure fuel pump internals a necessary purchase?

Would a ECU tune be necessary to use E15? You mentioned in your video that "early" model years may not be able to handle ethanol but I put E10 in my 2002 Mustang GT ever since I bought it in 2002 and haven't had any fuel line issues. But I do have plans to upgrade the fuel pump, injectors, and fuel line in preparation to install a supercharger.

Fuel system degradation on modern vehicles may not be a problem but fuel permeation still happens. Before I LS swapped my 2016 BRZ I ran E85 and after a while you could smell and see evidence of permeation on the rubber fuel lines (I didn’t touch the lines, tune only) Whereas when I ran gasoline I never had that come up. When I did the swap I did a custom PTFE fuel system.

The moon shiners put me on the floor lmao

When are you going to try a 100 nitrous shot in the red car? Tell me when you're going live -- and we'll have a watch party -- LOL

The cars internals have been updated since the late 80's early 90's and are able to handle the ethanol. So you could put ethanol in cars from the late 80's early 90's.

FANTASTIC! video, honestly But one thing I didn't grasp from the video.. Once you run flex fuel tune, imagine you JUST finished loading it but you have 93 in the car only, can I add any amount of ethonal to the car? Or does it have to be a certain percentage, and why can't I just run full E85 only on flex fuel? Cheers :)

Did my IE zf8 tcu and 93 stage 1 on my A7 last week. Waiting until after winter to flash the e85 file.

Good video!

Run WMI get the same Hp Tq as E85 and get your intake valves cleaned at the same time😎
