Enough with the technical jargon; what does this mean for engine longevity and performance? E85 will have lower internal cylinder temperatures because it burns roughly 30% more fuel. E85 will allow for more air molecules in each cylinder because air is denser at colder temperatures, increasing horsepower. The advantages of cooler cylinder burning temperatures, however, go beyond just this. Less heat will lessen the stress inside the cylinder because heat is what stresses the engine’s internals. Additionally, because e85 burns more slowly, there will be less chance of knocks, pings, and misfires in the engine. You can aim a more aggressive cylinder timing as a result, which will also improve engine performance.

No, to truly address your query. In particular, running an E mix without a tune to benefit from the higher octane is pointless unless you have access to E85 but not 93 octane, in which case you might run a low level mix, such as E20-25, to raise your octane level to 93.
You can run an E mix, not just straight E85, with a track. Depending on the condition of your LPFP and HPFP, the flow capacity of the system will restrict you to E30–40 on a standard fuel system. You can only go up to about E60 with an enhanced LPFP because the HPFP is your only real option. The only benefit of not having to mix the fuels is that a few people have been able to run straight E with just an updated LPFP. Generally speaking, in order to run straight E without experiencing fuel depletion, you need a secondary system (port injection) or a shotgun (Vargas Turbos).
I won’t comment specifically on the corrosive properties of ethanol because I’m not a chemical engineer, but I’ve used high% E blends on a few BMWs for years without any problems. Although it can be a problem, I’ve never actually encountered one.

Your 2020+ BMW M1000RR or S1000RR may be filled with either pump gas (91/93 octane) or E85. You may fill your tank with either fuel and still be able to drive on regular petrol thanks to our mapping that optimizes performance for that E85. You can run fuel from different stations without worrying about the content you are pumping if you can blend ethanol 30% in either direction. The bike will adjust for each so that you can use E0 (zero) to E30 on your pump map and E35 to E85 on your ethanol map.
- With the key advantages of being conveniently accessible, cleaner operating, and less messy/necessary than MR12, all while being available at many nearby gas stations, E85 produces more power than pump gas but somewhat less than VP.
- It’s affordable! E85 costs roughly $2 USD per gallon, while VP costs about $160 USD for 5 gallons (depending on your location).
- E85 won’t clog your spark plugs over time like leaded race fuel does.
- E85 won’t cause the same long-term damage to your catalytic converter or O2 sensors as leaded race fuel will.
The OEM wideband sensors are used by our Stage 2 performance modifications to modify fuel trims. Full-time closed loop (FTCL) refers to the fact that your motorcycle has a fuel map that it will utilize while you are riding and a lambda target that it is continuously modifying to hit. The bike will need more gasoline (approximately 30% more with E85) if you go from pump petrol to E85. When the bike requires additional gasoline, our FTCL calibration will detect this and adjust to meet a safe target. The M1000RR and S1000RR already have this capability out of the box, but only when cruising (not at full throttle) and only when using pump gas. We make particular adjustments for ethanol under various circumstances and variables in the program to ensure that the closed loop system is operating at all times.
because FTCL is needed for E85. You must have our 2020+ S1000RR Stage 2 (M1000RR Stage 1) mapping before making a purchase. Hardware is not needed! merely a software upgrade Since the middle of 2019, we have thoroughly tested this mapping on a small number of client bikes as well as our own shop bikes. The owners adore this mapping, which has been tested successfully in 210+ MPH drag racing, roll racing, casual riding, and circuit track racing. All of our beta testers concur that this mapping is fantastic, and we couldn’t agree more.

Can my BMW run on E85?
Here are a few factors to take into account before running e85 mixtures:
Do you have direct injection in your BMW? Your fueling system must be able to deliver adequate fuel because e85 uses 30% more fuel during each burn cycle. More fuel can be supplied by direct injection. In this case, choosing a stage 2 or stage 3 LPFP is an alternative. You can run up to roughly 40% E85 combined with 60% 93 octane pump gas on your stock N54 LPFP. You can run 100% E85 with a stage 2 or stage 3 LPFP, which produces significantly more power and is really less expensive!
-Do your BMW’s gasoline lines made of stainless steel? The question of whether or not e85 will deteriorate gasoline lines, seals, etc. is also up for debate. I would advise having stainless steel injectors and lines to be on the safe side. The majority of more recent BMW engines with turbochargers and direct injection have stainless steel injectors and lines, which are resistant to ethanol.
Do you have supplemental software? Additionally, your ECU/DME needs to be able to flow extra fuel. A stock BMW DME should have no problems operating with combinations containing E20. Most direct-injected BMWs can run around E40 fuel before the low-pressure fuel pump runs out of fuel, thanks to aftermarket software and tune.
Fair warning: there’s basically no turning back once you start running e85! I noticed my engine was operating stronger, healthier, and cooler after utilizing E85 for a few months. Despite the fact that E85 has excellent performance advantages, there is much more to it than just pouring E85 in the tank and hoping for higher performance. Before filling up with e85, I would advise anyone interested in running E85 to do a lot more study and make sure they have the right fueling system, modifications, etc.
How do I find out if my car will run on E85?
The U.S. Department of Energy advises keeping an eye out for the following indicators to determine if your car is a flex fuel vehicle: a flex fuel label or a gas cap with a yellow tint close to the gas station. Markers with the labels “E85,” “FFV,” or “Flex Fuel” are placed on the outside of the car. E85 is mentioned in the owner’s manual.
Does E85 harm engines?
No. Not at all, in fact. Providing your car has the appropriate tune or kit, is compatible with E85, or both (like an eFlexFuel E85 capability kit). Does your car work with flex fuel? Your engine will benefit more from using E85 than conventional fuel. Your engine, fuel lines, and fuel injectors are all cleaned by E85 flex fuel in addition to providing power. Because E85 contains up to 83% ethanol, it has a high ethanol content.
A great cleaner is ethanol. It removes deposits from the fuel injectors, fuel lines, and engine. Deposits frequently form in the engine’s combustion chamber, fuel lines, fuel injectors, and a few other locations. Because E85 is such a powerful cleaner, some individuals choose to use it in place of gasoline injector cleaners by running 1 or 2 tanks of it through their engines. Use E85 frequently as a reliable technique to guarantee that your engine stays clean (or all the time).
How does my automobile react if I put E85 in it?
Many more recent flex-fuel cars have been engineered expressly for E85 ethanol fuel. The chemical composition of this fuel is primarily obtained from biomass materials like corn. There’s a good probability your check engine light may on if you accidently put E85 fuel in a vehicle designed to run on ordinary gasoline derived from petroleum. And although though that’s never a comfortable feeling, an isolated error shouldn’t harm the engine. To be sure that your car won’t have any problems, you should still speak with a reliable mechanic.
Over time, using E85 in a non-flex fuel vehicle poses even bigger dangers. The continual use of this high-ethanol fuel can cause substantial fuel system corrosion in normal gasoline vehicles. Additionally, putting E85 fuel in a car by mistake could violate the warranty on the engine. That implies that even if your car is brand new, you can be responsible for the repairs.
Can any vehicle run on E85?
The most popular type of flex fuel on the market is E85. E85 gas is widely accessible in the Midwest region of the United States since ethanol is made from corn. Other areas, particularly New England and the Pacific Northwest, have less access to it. There are 3300 E85 gas stations open to the public throughout 42 states, according to the U.S. Department of Energy. Alternative crops are frequently used by ethanol producers outside of the US. Sugar cane is a significant source of ethanol in Brazil.
Brazil’s slightly warmer climate allows for the sale of pure ethanol at petrol stations there. Unlike E85, which is sold in the majority of the world, flex-fuel vehicles in Brazil run on E100. Unlike fuel marketed as E85, which always has an ethanol content of 85%, fuel sold as E100 is always 100 percent ethanol. Using ethanol with a guaranteed fraction makes it simpler for a car to operate at its most efficient and effective level.
E85 is the fuel of choice for motorsports organizations and enthusiasts in Australia. Because ethanol and methanol-based fuels tend to give performance vehicles higher thermal efficiency and increased torque, the motor racing business has long preferred these fuels. E85 can reduce the engine’s fuel consumption in a modern engine.
The US government has made an effort to promote the manufacture and sale of E85 by offering subsidies, particularly to Midwest maize farmers. Thanks to a $210 million grant from the U.S. Department of Agriculture, the construction of new ethanol infrastructure got underway in 20 states in 2016. The country will have easier access to E15 and E85 thanks to this new infrastructure.
Drivers will only notice a drop in miles per gallon when they fill up their flex-fuel vehicles with E85 instead of standard gasoline. Since ethanol contains less energy per gallon than gasoline, the impact on fuel economy increases as the amount of ethanol increases.
Especially when compared to conventional gasoline and E10, the price of E85 can vary significantly depending on the driver’s location and the ups and downs of the energy markets. E85 fuel is more expensive to drive with than ordinary fuel, even if it is less expensive at the pump. Flex-fuel vehicles frequently produce more torque and horsepower when using E85 in place of standard gasoline, but getting fewer miles per gallon.
Using E85 has advantages and disadvantages, just like with all consumer goods. the advantages are:
- less reliance on imported oil
- reduced atmospheric emission of air pollutants
- a greater tolerance for engine banging
Considerable drawbacks include:
- Use is only permitted in flex fuel cars.
- fewer miles per gallon due to lower energy per gallon
- Some regions don’t have access to it easily
