I have a 2005 Dodge Neon. I've been running E85 in it for almost a year now with no problems. The only thing I did was swap out the injectors with ones from a Ford Mustang that have a 25 percent greater flow rate. The computer did the rest, without a tune.

I'd love to see the computers learning values. Also, have you ever had to put 93 in due to lack of E85 in the area? We have E85 in most parts of this area, so not a huge risk to go corn-only here, but those long trips would be sketchy.

@@BlackthumbTV I have added a couple gallons of regular 87 gasoline a few times when I was running low and wasn't close to an E85 station. It ran fine and I actually couldn't really tell a difference. It probably just ran a little rich. For long trips, I run the tank down to less than a gallon and swap the stock injectors back in. Then I fill up with 87 gasoline and disconnect the battery to reset the computer. I did this before a 500 mile road trip during which I used 87 gas exclusively. I don't think the stock computer advances the timing when the E85 is added, so I don't think using regular 87 after using the E85 has any effect on predetonation (knock).

Love all the plot twists throughout the video, every single time I was about to write a comment addressing a caveat it was immediately addressed. Something that wasn't addressed though is that your stock fuel pump might be too weak to supply fuel to all injectors upon an upgrade, I've only seen this happen to really old cars which were due to have it replaced in the first place though.

I didn't realize that's all that FlexFuel was, and that you could upgrade an existing car to it. Thanks for real, bro!

Fun fact, Amazon sells e85 ethanol distillation systems so you can make your own fuel. Another fun fact, ethanol fuel was founded by Henry Ford which he called gasohol and every Ford vehicle till 1974 was designed to run on it. Ford was paid by oil companies to run vehicles on gasoline. But before gas stations dotted the maps people made their fuel at home with Ford's fractional distillation system. Amazon also sells e85 conversion kits for most vehicles. Enjoy your freedom from the pump!

I used to run E85 in my 96 Lincoln Towncar. That car loved it. Engine light would come on for the lean code. But it wasn't that bad, aside from its higher octane rating, ethanol also burns cooler. And it's great for cleaning carbon from the valves, pistons and heads. Similar results running corn juice in the 2003 Chevy 1500 van and my 2016 Ford Flex. When it was time for annual state inspection just run it low and refill with normal gas and the light goes away. Yes, all 3 cars had improved power, all 100% stock.

15% is the limit the epa sets for every North America ecu. That came with obd2 in 96. Every car on obd2 has to have a o2 before and after the cat.

@gregorymalchuk272

24 күн бұрын

What where typical limits before OBD2? Old GM vehicles had variables called "block learn" and "integrator", both from 0 to 255, with 128 being the target fuel trim. Does that mean that 0 to 128 only accounts for 0 to 15% richening change in lambda/fuel injector pulse width?

Fun Fact: In Brazil, Ethanol and Gasoline are the norm of fuel. Diesel is only for trucks. Ethanol gives more power, but more consuption. The gasoline is the opposite. ALL Vehicles from after 2005 have Flex Fuel Capabilities. Great video to see how a normal car behaves with Alchohol. (In Brazil its made with Sugar Cane). The car with Flex Fuel can run in ANY mix of gasoline and Alchohol. But it has its downsides, as the engine is "bogged down" having to work with two fuels, and there's a saying that goes somewhat like this: Flex Fuel Engines are Engines that are made to run Ethanol, that are forced to run with Gasoline. There are engines that when running in 100% Sugar Cane it gives 5 hp's more! (its not insane but its quite a bit more power).

In 2003 VW Launched the Flex Fuel with the Gol G3 1.6 Power, and generating a whole new Flex Fuel ecosystem here. (In the late 70's and mid 80's when the fuel crisis came, we found out about the sugar cane fuel, and to prevent having no gas, vehices from that era, specially after 1976, were manofactured to run on Ethanol instead of Gasoline, with cars returning to gasoline in the mid 80's) Specially back then, the Ethanol vehicles needed special carburetors and fuel systems to handle the water on the Alchohol, that could corrode the normal carburators and rubber hoses.

I have an 01 Audi A4, it's been very modified. Plus I personally tuned it but I switched to E85 + methanol injection. This car uses lamda not AFR. So when I switched to E85 there was very little tuning involved. Honestly it probably would have ran fine without. This is after a much bigger than stock fuel system.

E85 has awful fuel economy. That’s a big downside.

Well of course, he just mentioned it uses 33% extra fuel.

My emissions were to high during the yearly inspection. Filled the tank up with e85 and passed. In the end i did replaced the lambda sensor but it was funny to look at the face of the mechanic when he looked at the numbers.

Dayum boy Hella fun this guy

I was like...this dude just swapped a fresh motor to grenade it with e85? no way haha

I love that you dont over explain things

I use 50%+ E85 in my 2005 PT Cruiser GT (turbo motor). Been putting in E85 for a couple of years. So far, so good. (Had an 06 PT GT before that that I used E85). I do get a little less mileage to the tank vs. pure 93 octane dino gas, though. *edit - I'm also running a Diablo Sport tuner with the factory Diablo tune.

the key is mixing it. running it pure dries out the plastics and wire casings because the alcohol. the lubrication from regular gasoline is key.

I always wondered if I was adopted. Thanks for clearing that up.

Instead of more fuel, what if you injected propane into the intake to prevent the engine from going lean?

Should probably let people know e85 eats rubber and ruins all the seals in the engine….. maybe you didn’t know 😂

Used e85 in my 00 crown vic interceptor back when fuel was skyhigh. It worked fine and only lost about 2mpg. There was a flex variant of that model but mine was not one.

An example of an ECU "over learning" is when a flex fuel sensor reads the wrong ethanol content of the fuel and adds way to much fuel, potentially causing the engine to stall or not run at all... I've seen it a few times, and simply resetting the values is usually the fix

i noticed a 50% regular gas plus 50 % e85 gives more performance with only sacrificing some mileage

That’s why you can typically expect 2 to 3 miles per gallon less on the 85. So it really doesn’t save you any money by running only E 85.

I put some in my Toyota Prius coming back from Virginia to New York. It was substantially lower priced than regular 87, so I pushed the button and filled my gas tank just to see what would happen. The answer is, nothing. I believe my fuel economy went down slightly, but the car ran 100% normal, cruise control set on 75, not so much as a hiccup. But I think on the long-term it would be a problem. At least that’s what I have been reading.

I tried it once on a Carbureted 9.1 to 1 compression V8. It didn't work. The compression wasn't high enough, It was way down on power. The fuel hoses and any rubber - ish parts turned to mush or turned rock hard. I had to rebuild the carb internals and replace the mechanical fuel pump. What a mess. But it sure does smell Good !

i ran E85 on a Stock Citroen from the early 90s for quite a while, you need to slowly change over from normal fuel to E85 and back, if i quickly changed over it then went into limp mode and got the same issue as you did, i am guessing the ecu might be able to correct both long and short term fuel trim and thats why it's fine? I don't really know tbh, it just worked.

the regular gasoline lubricates the rubbers and casings of everything in the fuel system. stuff will start becoming brittle and cracking leading to shorts in things like the pump if you run e85 too many tanks before switching back to regular fuel. I like the idea of mixing the 2 getting the best of both worlds with low knock from e85 and lubrication/longevity of regular gas.

This sh!t is mint! Lol. Keep it up.

Flex fuel vehicles are OK to run regular petrol gasoline or E85, including a mix of the two. You will get less "mileage" on corn, but it is cheaper. So you'd have to do the math to see which is cheaper at the end. Best of luck!

The manual for my 1969 Buick Skylark says to raise the float level .050 and advance the timing 6 degrees to get improved performance and increased milage.

Enjoyed the informative and Comedy

11:05 aight you got me, I’m in 😎

Now this is what I need goofy but helps learn

People shit on the LS4 being a FWD LS engine but my Grand Prix GXP was one of the easiest cars to add Flex Fuel too I've ever worked on, the factory injectors and ecu are both compatible with a tune on a stock (for now) engine and all I needed to add was an Ethanol content sensor and it ran better than it ever did on 93, plus where I live e85 is readily available and 30%+ cheaper than 93 so it was saving me money too

When running e85 or an Emix you need a tune most of you are already aware I'm sure. The big thing with runnjng more than say a e25 mix on a stock fuel system is going to cause potential misfires because the more ethanol you run the more fuel volume required for combustion, stock fuel systems typically the HPFP aren't meant to run usually beyond a e15 mix on a naturally aspirated all depends on the specs of the vehicle make and model, also another note you should never leave heavy e85 mixes just sitting in your car, it has alcohol and it seperates into water and leaves a gummy oil gunk mess if you dont frequently run higher octane fuel like 91 afterwards and run 2 tanks of regular fuel after your e85 mix, basically only run the e85 mixes when you are planning to race it or test it

If you have a vehicle that uses factory widebands you can. I see people running e85 on the newer Kia souls that can't use it yet they run fine. Just acts funny on first startup until it warms up and enters closed loop. Narrowbands won't do it and not all wideband vehicles will because of the stated learning limit.

I personally break the law this is probably like the 10th E85 video I watched in past 2 days. Been wanting to modify my car, specifically my prius, for flex fuel for so long. I know it's doable, but to do it proper it's a project (for me) and there is no real value to doing it, I just want to!

As a 2002 Subaru Legacy Outback owner.... I love you ❤❤❤(and want to see what happens to this car) 🤣🤣

I see a few common questions, so here's some answers! - E85 is better for performance engines as it has a ~105 octane rating. Research how octane rating effects high compression and boosted engines for more info. - E85, while technically getting "worse mileage", is still cheaper doller-per-mile than 93 (at least in my area) - E85 burns much cleaner than petrol meaning less carbon deposits, and even tends to clean existing carbon off engine internals. - The jury appears to still be out on whether or not it's "environmentally friendly" on the whole, I see sources on either side of the fence. - "IT RUNS FINE IN MY NON-FLEX CAR!": Some cars ECUs will learn around the additional fueling requirements different than others, this is an example of what can happen and how it can cause damage. Show me datalogs, then we can talk. None of this is new, this info has been around forever. All we do is show the literal data coming from the car in the real world and describe the potential ramifications. Not sure why some of you are trying to make this political, but take that crap back to Facebook (or whatever hole you crawled out of.) This is a low-buck performance car enthusiast channel, we don't do that here. Go outside.

I have an 09 Impala that is a glex fuel ready vehicle and I just stsrted having the issues starting when its cold due to the sensors thinking its starting out with more fuel than it actually is. If I press the gas pedal a little it starts right up which is a known issue with these vehicles and replacing my Idle control sensor or Cooland temp sensor should fix this issue in my case. My point is that even in vehicles that are E85 ready the CPU can have the same issues if a sensor starts to malfunction or the ECU cant properly detect which type or what mixture of fuel is actually in the tank.

Worth it

Always a good laugh 😂

06:00 was wondering how you were getting the table stats!!

Wonder how the AFR on my s10 is lookin😅 got some bent pushrods on intake and exhaust side and I know bent pushrods at least on the exhaust side means it's not burning all the fuel and on intake meaning it's not getting enough, new ones on the way problem should be fixed soon👍

Legend

I have run moonshine (that my DAD made) in a 72 Maverick- and it burned the wheels off-- later when we dismantled the engine for rebuild- it was clean as a whistle inside- NO carbon AT ALL. It was like racing fuel...for real!!!

Now how would E85 affect a Volvo S60 from 2001 with BSR chip tuning for 50 more horses and fuel economy.

I approve this video

How would this apply to carburetors and tuning it to run Richer may be a stupid question but would this not mean it's going to burn just as inefficient due to it needing a high volume of fuel to burn rught

Ethanol can make rubber and plastic brittle if not designed to handle it.

I've run e85 in a bunch of different cars and never a real issue. My 99 neon ran like crap at first and I thought I ruined it but after about 50 miles it cleared up and was always fine after that so I figured it absorbed water already in the tank and once it cleared that it would run fine. My 99 maxima for some reason got better mpg on e85 (not flex fuel car). Flex fuel cars add a butt load of fuel and get worse mpg, non flex fuel cars don't know to add that much but they add enough to be OK, most stock ecus add up to 25%. Also running leaner than stoich does not burn hotter, stoich is hottest and is the reason we run rich at WOT, typically 12.5 or so on gasoline, 14.7 melts pistons at WOT without the excess fuel to cool it, leaner than that it starts to cool down again but makes less power and won't keep the cat working as well so we don't generally do it.

It makes one wonder that if E85 produces cleaner emissions then why aren't all modern vehicles produced with flexfuel capability. It would have to be flexfuel since E85 isn't available everywhere. I'm installing a flexfuel kit on my Mustang this weekend in preparation for a supercharger. I've been told that I can run E85 without a supercharger but as you mentioned in your video I would need to upgrade the injectors regardless if I have a supercharger installed. Not sure if I need to upgrade the fuel pump for more flow just yet. I just replaced a defective fuel pump last summer - that sure was fun 🙄.
