What tune do you need for E85?
We suggest completing a tune with fresh 91 octane gasoline first since this is most likely to already be in the fuel tank. Then, completely drain fuel tank and replace fuel with E85 (preferably E98). The in-tank fuel pump can be used (some ECUs allow the fuel pump to be turned on constantly) to drain the fuel tank.
What does tuning for E85 do?
The trifecta of higher boost, optimal timing and a denser air charge can allow a given setup to produce significantly more power. On a stock turbocharger, it is not uncommon to achieve 40 to 50 more peak horsepower over gasoline. On larger turbo setups, it is possible to gain 100 or more horsepower by using E85.
Does E85 require tune?
Because E85 requires a completely new tune you must ensure that you are only running E85 in the tank when using E85 tunes.
Is E85 better than 93 octane?
E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.
What happens if you run E85 without tune?
Running E85 on older model engines without tuning and replacing some components will ruin the engine in short time. and other components besides tuning your fuel system, can easily run the bill up since you need to change so many components to properly run E85 fuel blends.
How much more power can you make on E85?
Based on the results of the two dyno graph comparisons, you can see that with the same engine, tuner, and turbo combination this 1.6L engine saw a 34 percent increase in tunable power when using E85 fuel. This is a great case study on the main benefit of E85 as a fuel source when compared to pump gas.
Is E85 bad for your engine?
Due to the higher ethanol content, E85 has a greater resistance to detonation than regular gasoline and will also have a cooling effect on your engine. If you are running E85, it is always a good idea to test your fuel for ethanol content before fueling up.
Does E85 Lower Your MPG?
The Iowa Corn Growers E85 Web site says that if you have a flex-fuel vehicle and burn E85 (85% ethanol, 15% regular gasoline), you’ll experience a gas mileage drop of 5-15% compared with regular gasoline. Taking the middle, a car that gets 25 mpg on regular gas would get 22.5 mpg on E85.
What do I need for E85?
– Fuel lines and hoses, especially inside the tank. – O-rings and seals in the injectors, filters, couplings, and sending unit. – Fuel pressure regulator. – Fuel filters, stainless mesh filters are best. – The fuel injectors and the fuel pump need to be compatible with E85 and sized to deliver more fuel. – You may need a cooler spark plug to reduce the risk of pre-ignition.
