[@harryazzole7814]

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.

[@T0tenkampf]

[@TheFiku]

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

[@gaudie]

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

[@QueZika271]

But our ethanol(E100) is hydrated and has 5% water in its composition, and because we do not have inspections at the stations, this percentage is often higher, causing several long-term problems. There are many e85 stage 2 cars here in Brazil, and I've never seen any of them having the same problems as cars that use e100

[@TheAutoChannel]

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.

Drove it like that from the 2nd week i bought it (new i. 2006) until i sold it 5 yrs later. ZERO issues. Drove it daily had my kids in it, track days unfortunately i got divorced and needed money so i had to sell it.

getting between 220 and 295 is a huge difference. Are you actually calculating out the numbers or going off the cars cluster info? Because that cluster dash info is not accurate. People that I know that have tuned cars running E85, usually, Lancer Evo guys, get about 40% less fuel economy. So why yours is only dropping 10% doesn't make sense to me🙄Could be the efficiency of the DI motor? But I'm calling BS on this one🧐

[@NerdGenius]

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.

[@EddySpaghetty]

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

[@Prima_Nocta]

[@deweberis2709]

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.

[@fascistpedant758]

Burning any hydrocarbon produces CO2 + H2O. The water vapor produced by the combustion of hydrogen has no latent heat of evaporation. If anything, any condensation of the vapors adds heat to the charge.

[@otterconnor942]

Ethanol evaporates much lower than operational oil temperatures. Just like with water, it'll be sent through the pcv system and burnt, as ethanol and water can not remain in a liquid state at those temperatures and pressures. Just drive your car long enough to pass 212° oil temp and neither will be in your oil in significant amounts.

[@CotyOsCA]

@@otterconnor942 Naive driver here… so are you saying we don’t have to change the oil more often?

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.

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?

[@fascistpedant758]

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.

[@larsjrgensen5975]

Depends on the car model, many (actually I think most) ECUs run without O2 sensor when full throttle, the stock O2 sensor is not wideband enough to work at both low load and full throttle. At full throttle the engine runs from a map and not the O2. Also the AFR needs to be different with E85, so the engine will try and reach gasoline AFR even though it runs on E85. My flexfuel car smokes like a diesel at cold idle, because it is tuned to run on E85 as default, because that is the hardest fuel to coldstart, the ECU in my model then needs to burn the gasoline before it can calculate what fuel it is burning.

[@Deutscheautoparts]

Yeah probably fine under normal driving but I would be concerned that under heavy load you would lean out. FYI we logged fuel pressures on e85 on stock tune and it didn’t have an issue keeping the pressures.

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.

Really enjoyed that 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.

[@shannonmcatee9610]

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

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

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.

[@miguelsanchez6465]

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!

[@BillySBC]

Being that Ethanol is made from water, yes it makes sense it would absorb water. Ethanol is alcohol which is made from water and sugar and yeast, so it's a water based fuel.

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

[@Technix77]

the real question is, does eating more corn make me faster?

[@tkrogs3535]

Can't wait for summer. Mk7 is38 ie tune and have their new flex kit. All I need to swap the hpfp hoping 380whp 🤷‍♂️😂

[@adamgoof]

I run E85 in my 2012 Tahoe police edition instead of putting 93 octane in it and paying four dollars a gallon. I paid 250.

[@merafekalier9284]

Anyone ever heard about SAAB Biopower? SAAB solved the problems of the E85/Gasoline mixture long ago before every other car brand.

Vilket jävla namn xD

@@Samadork bästa namnet, ingen kan slå det. En gammal mail jag har heter även Bajsglufsarmorfar. Den är mäktigare än Ryssland.

Running Audi A3 on E85 tune IE freakin love it just hates cold weather 😂😂

[@jackmcdonald8355]

Awesome video!!

[@davidreyes6660]

I’ve been waiting on the IS20 trueflex tunes, hopefully I don’t have to wait too much longer Edit: Sike just realized it’s on your website but not IE’s website

[@Deutscheautoparts]

We had a beta

[@jaredyoung6519]

Love the video!

[@TopiasSalakka]

You could've mentioned that it's made of corn only in the USA. The source varies by country, in Finland it's made from biowaste like old bread.

[@m32mikestu]

I made my decision . E85 in my e85 , m54b25
