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.
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
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 💯
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 ;)
Better than my stock Evo X GSR. The stock X i had went about 160 miles out of a tank of gas. My Evo 9 MR which to date was my favorite car i ever owned (had the privilege of owning 4 evo's since 2003) my MR i kept conservative mods only photons and a good tune running 91 pump I made 360awhp with WMI 400. 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. If you were getting that kind of mileage on E85 with that kind of power that is VERY GOOD. Best tank miles i got out of my 9 was about 220 on a tank making half that power you had and i was on pump 91.
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.
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.

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 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.

Thanks for this info I'm running E85 in both my old 90s Mazdas both have Big Turbo so this comment really opened my eyes to understand how E85 truly works.
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 😩
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🧐
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.
You can run a 93 tune using the Lucas booster and 91 octane. The Lucas is good for about a 3 pt increase, using the whole 15oz bottle. Works well when all you can get is 91!
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'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
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.
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.
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
@@alexwitachoppa8801 on a full tank of E around 280ish miles, that’s with me not going the speed limit most the time lol I’m sure you could get 300+ miles if you drove normal. I’ve gotten 400 miles on a fuel tank of 93 just the other day.
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.
Am I missing something? I purchased the stage 2 tune for my 2015 gti but it dont have the flexfuel tune file. Only seen the stage 2 hpfp and e30 files.
People with these direct injection cars need to make hpfp upgrades that flow twice the amount of stock then you should be able to go stage 3 with the proper low pressure upgrades and go back and forth between e85 and premium... mixing e85 is a stupid hassle
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.
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!
With E85 (Ethanol), carbon build up would be significantly less than with pump gas. E85 burns a lot cleaner than pump gas because it doesn't have nearly the amount of petroleum (oil) as gas does.
My ford truck has the yellow cap that says E85 so if choose to use E85 once in a while or wtf I would still need to upgrade parts? Or what would that be for the people that do conversion kits or do the tune ups?
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)
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.
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 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.
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.
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.
Hey I lost my long coding to my abs modules can u pls help I plugged in a cluster that wasn’t for my car the immobilizer was active I put my original cluster back but now I can’t get rid of these nasty lights pls help
In theory, could you run 93 pump and E85 with a tune to get both the everyday driving to track without reflashing every time? Also....Sorry if you mentioned in the video, I'm working and listening...What other modifications were done to the GTI in the video?
hello, how is everything ? Was the power measured by the wheels or engine? how many degrees does it advance in this map ie 93 octane and e85 map at redline rpm. and what turbo pressure and advance of this map ie 93 and e85 on is38 on gti mk7 can you tell please? thanks
so i have a MK6 R running a HPFP on a Stage 2 Racingline tune, can i run say E30 or even to E70 without having to retune the vehicle. and maybe just install a Ethanol Senor.
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.
I have a issue with my Mk7 with 100,000 miles. A misfire on cylinder 3 only, misfire is only on idle. Did compression test 190 on 1,2,4 and 160 on 3. Changed spark plugs, coils, injectors, and did a carb clean. Any help on what it could be the issue would be appreciate it.

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 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.

Thanks for this info I'm running E85 in both my old 90s Mazdas both have Big Turbo so this comment really opened my eyes to understand how E85 truly works.
That answered all of my questions, thank you!
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 😩
I'm in CA, since I only have 91oct I blend e85 and use Cobb stage 3 93 oct map on my mk7 gli. Runs good!
Integrated engineering has one
Yeah I'm waiting for COBB to release E85 support too. Have they said anything about their progress on that?
you suit what mpg now 😀
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🧐
I always loved how GTI's produce far more torque to power ratio and makes it feel so much powerful than what it is
That doesn’t make sense and they don’t make more torque to power than many other cars. It’s fast because it’s a 3 thousand pound car
Thx so much for a great video packed full of great info! Your GTI is looking sweet!!
Happy Thanksgiving Shop Dap.
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.
You can run a 93 tune using the Lucas booster and 91 octane. The Lucas is good for about a 3 pt increase, using the whole 15oz bottle. Works well when all you can get is 91!
thank you great info
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
This video is very high quality
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.
Brilliant video Paul!
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
Totally want a tshirt! Prolly won’t make the switch to E85 anytime soon, but that is a cool shirt.
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.
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.
No fuel system upgrades needed on 5.0s luckily! Runs so much better on E85
Same for ecos?
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
do you know how many miles you’d get on a full tank
@@alexwitachoppa8801 on a full tank of E around 280ish miles, that’s with me not going the speed limit most the time lol I’m sure you could get 300+ miles if you drove normal. I’ve gotten 400 miles on a fuel tank of 93 just the other day.
@@zeke6541 where do you live? I'm in NY and have likely questionable E85. I'm considering the EQT E85 map myself.
Very, very rich information. Thank you
New camera be hittin' different
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.
Wait you can run straight e70 to e85 in a stock gti??
Am I missing something? I purchased the stage 2 tune for my 2015 gti but it dont have the flexfuel tune file. Only seen the stage 2 hpfp and e30 files.
Wait you can Just add e85 to the fuel tank with no other mods?
Since I have an 02 GTI, I assume degraded fuel lines are going to be a problem for me
People with these direct injection cars need to make hpfp upgrades that flow twice the amount of stock then you should be able to go stage 3 with the proper low pressure upgrades and go back and forth between e85 and premium... mixing e85 is a stupid hassle
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.
Great job guys!
Great info... I'm full apr2 stock turbo gti... Been wondering if I could use a small % of e85 for spirited driving days.....
Really enjoyed that video
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!
I know this is an old video but I have a 06 Audi A3. My question is. . . Can I pump e85 if I upgrade my mechanical pump? And of course tune it.
nice video. If it was Charles, he would have make 5-6 videos out of this one video
Can E85 sludge/gum build-up in the HPFP occur in these VW's? or is that only in older vehicles with hpfp's?
no it cleans deposits
Thanks for the detailed info. Do you know why in Europe they do not recommend Flexfuel for direct injected engines?
So can I just use regular gas instead of e85 and if so can I completely use it and never use e85?
I’m interested to see the carbon build up on these cars vs pump gas
With E85 (Ethanol), carbon build up would be significantly less than with pump gas. E85 burns a lot cleaner than pump gas because it doesn't have nearly the amount of petroleum (oil) as gas does.
My ford truck has the yellow cap that says E85 so if choose to use E85 once in a while or wtf I would still need to upgrade parts? Or what would that be for the people that do conversion kits or do the tune ups?
Did my IE zf8 tcu and 93 stage 1 on my A7 last week. Waiting until after winter to flash the e85 file.
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)
Can I run 2 gallons of E85 per tank safely on a ecu tune?
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.
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..
Is your stage 2 tuned for 93 or e30?
@@Kevin117 I have a GIAC stage 2 93 octane tune. With GIAC 93 tunes you can safely run no more than 3 gallons E30 when filling up my tank..
How much do u need to calculate to mix 91 and E85 to make 93 octane? Here in CA we don’t have 93.
So you can run e85 having stick tune and stock fuel system in the mk7 gti
I need to know where those stations are around Charlotte. Having my Focus RS dyno tuned for E85 next week.
Great video. Great explanation. Cheers!
Glad you enjoyed it!
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.
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.
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.
Hey I lost my long coding to my abs modules can u pls help I plugged in a cluster that wasn’t for my car the immobilizer was active I put my original cluster back but now I can’t get rid of these nasty lights pls help
Does the GTI have a port injection or a GDI engine? I heard that the high pressure fuel pump doesn't like alcohol which provides less lubrication.
In theory, could you run 93 pump and E85 with a tune to get both the everyday driving to track without reflashing every time? Also....Sorry if you mentioned in the video, I'm working and listening...What other modifications were done to the GTI in the video?
hello, how is everything ? Was the power measured by the wheels or engine? how many degrees does it advance in this map ie 93 octane and e85 map at redline rpm. and what turbo pressure and advance of this map ie 93 and e85 on is38 on gti mk7 can you tell please? thanks
so i have a MK6 R running a HPFP on a Stage 2 Racingline tune, can i run say E30 or even to E70 without having to retune the vehicle. and maybe just install a Ethanol Senor.
I have a stage 3 APR MRK6 GTI how do I install and e85 to onto my car and will that affect my stage 3?
i just wanna jump between 93 & e85 on a 2020 5.0, what do i do
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.
thumbs up for Mr. Lahey reference
I have a issue with my Mk7 with 100,000 miles.
A misfire on cylinder 3 only, misfire is only on idle.
Did compression test 190 on 1,2,4 and 160 on 3. Changed spark plugs, coils, injectors, and did a carb clean.
Any help on what it could be the issue would be appreciate it.
Awesome video!!
