Can you run E85 Fuel in a MK8 GTI? 

Flex Parts and Tune coming soon - We will link here when available! In the mean time go buy some stuff from ShopDAP.com

Just here to remind people how nice 200hp felt on a 1.8t full bolt on in 2000, what a time

Paul breaks it down so well for all of us. Nice work fellas! We can't wait to get these kits into customers' hands! ⛽🌽

The MQB and B9 platforms are so blessed by this amazing ingenuity from the OEM and the aftermarket to introduce smart solutions to utilize it. This otherwise stock car is producing similar power to my FBO E85 IS20 MK7 - which I consider to be perfect for a daily. I'm impressed how easily this gets there on a beta map from a brand known for "conservative" power tunes. Thank you for the great content!

My B7 1.8T can run on 50:50 93 and E85, as it shifts the LT fuel trim ~15%. Usually my 100% 93 LT on 215hp with TT injectors sits at -4%. That gives me some margin to the +15 LT boost cutoff. The torque increase is noticable.

"oh step fuel line" 😅

Love Ya Paul ..You take the effort to explain for all ..Refreshing to see and Hear

I cant wait for this! I have been running the unitronic e85 tune on my mk8 gti for awhile and its great. At e74 my car made 376whp and 431wtq with just the tune and bolt ons. My only issue is having to switch back to the 93 tune when i know im going to be driving in an area that might not have e85, this solves that.

As always, great stuff. Tell Charles I expect to see him do a video of the kit for the R lol. This seems like this is be absolute best idea and option to go with for these cars!

The most I can do is e10. My 1.2t corolla goes sooo fast on it. The 0-100 drops to 10sec. Amazing

Unitronic were going to release this for the Mk7 - I SO wish they would!!!

That’s some serious power. Congrats! 🎉🎉

I have owned flex fuel cars for a long time and love the stuff. Wish my new Challenger was flex , hope they make a kit for it for when its out of warranty.

That's pretty cool that someones figured out how to run E85 on the VW ECU. Even more amazing that VW have even made this a possibility!!!!

I used to add about 2 gallons of E85 to my 99.5 Audi A4 1.8T full bolt ons with a mystery tune i got on Ebay...it was for 18psi so i put E85 in it and set my high boost at 25psi on a KO4. I ran it that way for almost two years.

This pocket rocket sounds really good on the dyno. Nice wheels and paint color too.

6:23 If this wiggling method doesn't work--for example, on an older car with some rust built up like mine, or if somebody's watching this 10 years in the future--there are wiper puller arm tools that exist that can help get the arm off. What you DON'T want to do, that I did, is put too much pressure on the bottom of the windshield, trying to pry it off. That's a great way to break a windshield, and then you might have to spend $400+ on a new one.

Man that spoiler looks good

I have a couple questions and they have nothing to do with this video. Lol. So i recently purchased a used 2020 VW Golf GTI which i am guessing is a MK7 because of the year. I also am pretty sure it is the performance package. Red gti on front and back. Red gti calipers. Had no idea it was tuned when i purchased it. All they told us was that it was straight piped. So we have no idea what kind of tune or what stage or anything like that. Recently it has started to have a long startup when turning the key. Sometimes it will start good and sometimes it will not. Second time you turn the key it will start up good. The epc light has came on a couple times. Itll lose power and start jerking when you try to accelerate over 30-35 miles an hour. But if you turn the car off and back on itll usually stop. Sometimes it takes more times than others. I have codes p0302 for misfire in cylinder 2. P0413 for secondary air injection valve circuit open. I switched my 1 & 2 coil packs to see of it was that. After doing so i got the same misfire code for cylinder 2 and cylinder 1 now has a p0301 code for misfire. But now i got another code that is p0300 and it says random/multiple misfire detected. The last code i am getting is p0420 and it says catalyst system efficiency below threshold. Since we werent told it was tuned we were putting regular gas into it. We recently changed that to 91 octane. I changed the sparkplugs. And now have 2 coil packs coming to change them on cylinder 1 & 2. I hope that fixes it. Lol. I honestly do not know alot about cars. Any help is appreciated.

Hello , can you try a resonator delete on the gti ? Thx have a great day from 🇵🇹

That Uni kit is impressive. Can they build in rolling anti-lag with the fancy tech? Boom shaka-laka

You can use a simple PEX crimp tool for those fuel line hose clamps. Search for "single ear crimp tool" and you'll find them between $10 - $20. Or any friend that has done PEX plumbing should have one.

Damn those numbers are impressive.

Love it. You guys never disappoint. I’m wondering what hardware I would need for the R but time will show

Paul, your coolant is looking a tad low at 9:50.

Any particular reason you dyno tested with hazards flashing?

I always wondered how fuel affect stage 1/2 and stock cars. Really interesting.

Yellow is gorgeous on this car

Now I want to get a mk8

Maaaaate! That t-shirt is killing me! So appropriate!

So when will you talk about history of BMW's Xdrive AWD system

In every video you remind me how much i would love to have a gti for daily until my bank reminds me i cant afford it ^_^

3:19 this is completely safe - Jeremy Clarkson

I hope they make this for the Mk7 1.8T...I have E85 everywhere where I live!

I used to do an E15 mix in the summer and the butt dyno would feel like how the car boosts in the winter with cooler weather. maybe it was placebo, maybe not.

Fucking love how unhinged paul is 😂

Great video, I wonder if UNI will test E85 on the new R/S3?

Hello, I would like to ask about my 2022 MK8 GTI S. It has a total of 13,000 kilometers. When I changed the oil, I smelled gasoline in the oil. But I drive 80KM to and from get off work on the highway every day. There is nothing strange about the car. I should what to do

I want a mk8 so bad 🔥🔥

You most likely will not see any performance gains above 55% ethanol on 95% of setups. The difference from 55-85% of ethanol is MAYBE (a big maybe) a degree of timing. We didn't make anymore power after 60% content with a 2867R on a mk7 flex tune.

Can 'running a mix of e85 and fuel' help clean engine ? Older golf 1.8t

Do you need an upgraded low or high pressure fuel pump, or additional fuel rail that feeds into the ports? Or does this set up only require the tune and the sensor?

Thanks a BUNCH for this video! Quick question: is it still recommended to run a tank of standard gas (93) every 2-3 tanks of E85?

Man I wish you guys stocked C4 chassis parts.

How does the sensor mount on after market fuel lines like precision race works

Just a question, why did you pick the GTI over the R?

400hp wheel? That's like a monster tune on a EVO just 10-15 years ago. And this is stock block and stock turbo.

I dont know if I overlooked it in this video. But what mods besides the intake and e85 do you have? Turbo elbow, charge pipes, intercooler? Or can you achive these numbers with just e85 , intake and exhaust?

I want vr6 12v content show og stuff

Can't wait for the "Can you run E85 Fuel in a MK9 GTI?"

Is there engine differences between the gti clubsport and r? I know some of the auxiliaries will be different but are the engine internals different. Eg will a flash of a gti get me to the same point as a clubsport

What happens if I add a gallon or two of E85 on my mk8 GTI with a stage 1 tune? Will it cause any harm do I need any physical modifications such as an hpfp? Will I see any power difference?

I'm pretty sure you can plug that into the wiper motor with no issues on the can bus...

Never heard about the job posting plus compensation..

Do you sell a new oe hose if someone would want to remove this for something like a dealer visit?

Good grief! Can you make one for a 981 Porsche Cayman S? This isn't a turbo, but I'm sure it could make more power. A simple reflash nets 27 horsepower on this 3.4 liter engine, but that costs $1200~! With E85 capability, this would make a good bit more than 27 extra hp and would make it worth the price. Great video! [I'd like to hear what the quarter mile times/speeds are like with the GTI on E85....]

Do I have to upgrade the clutch for it to handle 400hp???

I want this kit for my 40th AE GTI. What is the part number for the unitronic ethanol sensor kit?

So if I flashed my mk8 with the e85 tune without the ethnol sensor and gauge on pump e85 is that a no no? Should I wait until I can get those or should pump e85 be fine

What are you hearing will be the hardware requirements for mk8 R? Please spill the beans!

Hi man sorry for going off topic but can i ask why do some mk8 gti get the old generation Gen3 engine with same IHI is20 and some like the UK/US ones use the new Evo4 engine and Garrett turbo? Not sure if you know why vw will be doing this to their customers by selling them a mk8 gti with old gen engine and turbo with small updates here and there thanks.

Were there other parts/mods done to this Mk8 GTI before the dyno? Downpipe, etc?

Is it possible to install this flexfuel sensor in a Jetta MK6,5 with the 2.0 EA888 gen3?

Any one know when is available? I have one year waiting for this.?

how does the ECU know what to do with the flex fuel signal? part of the tune?

Can you run Paul in a E85 GTi

Possible for a mk7 golf R?

When will they be releasing the flexfuel kit n tune?

What’s the eta on this kit?

Would this require an intercooler, downpipe, etc?

How would you like an advert... YES

Where can I get this module ?

Nice kit for a simple install! Just wondering though -- are other fuel system upgrades required? Injectors, LPFP, HPFP to accomodate for the increased fuelling requirements of E85.

I hope they can figure something like this out for the Mk7s, sounds so easy to just throw in pretty much

Any gains on 91 octane (10% E) ? No 93 here.

Just full send it.

Is that GTI lowered? What wheel/rubber size are you running?

Yoooooooo wait wait wait!!!!!😮…. This is a great video and all… BUT , can we talk about VW not color matching the engine bay… REAALLLY VW?????😮😂

In Iowa e85 is at every gas station at this point

whats the kit you have on the exterior ...it looks beautiful with it.

6:51 What is that and what does it?

HPFP required for full e85? I know my MK7 maxes out around e40-e50.

Hey Paul is your car still running a stock DP?

Apples to oranges Paul. A 5 gallon bucket of water weighs more than a 5 gallon bucket of fuel, lol.

Why should the Dyno Number be Different in the Summer?! The dyno should recognize it and should consider it in the calculation. 🤷‍♂️

Anything after E40 and you’ll start seeing diminishing gains. This is because once you run a fuel that gets you close to MBT and making out the turbo there isn’t much left. You’ll hit a certain point where adding ethanol content will result in no power gains, unless you have a severely knock limited setup. You will however continue to see better turbo response due to the extra fuel mass ethanol requires. That more of a linear relationship to ethanol content.

Can we get a stock 87 to 93 comparison sometime please. Inquiring minds want to know!

Early gang tune tf in

Its simple... Worse Worser Worstest...

Worser is not a word.

RU-vidr discoveres flexfuel systems. my old junker can run on E85 if i install it. also brazil says high

Notification SQUAD!🔥🔥🔥

Shaking lol 😂😂😂

Hat really sucks is my 2014 Audi A4 is a factory flex fuel vehicle. I'm currently running Intergrated Engineering's stage 2. And since nobody offered a flex tune it's set up for 93. Well experimenting I got the car to 70 ethanol and lost over a second 0-60mph, and 2 second in an ⅛ mile! Roughly 50hp! And again the car is designed for it!

We should call ourselves VWAGots. Which sounds like a slur, but just tell everyone that you offend how it's spelled, and I'm sure they'll understand

kW is power, not torque ...

No😊

I honestly dislike the soundaktor

Coolant hose over the intake?! Common!!!!!

Why ? Ethanol is trash
