E85 fuel

[elitee]

So I have decides I will be running e85 but I just have a few question which I have been reading alot of mixed replies about.

1. Is it necessary to upgrade all fuel lines to stainless steel with Teflon inners ?

2. The fuel filter will most likely need to be replaced but is there an aftermarket fuel filter I should run or will OEM suffice?

Problem I see with E85 is where do you get it ??


Be buggered if I would plan my driving trips restricted to finding E85 outlets its hard enough to find 98 once outside Sydney metro

Pump or Drum E85 still mean that you will be using more fuel hence injectors and possibly fuel pump need to be upgraded to suit the new fuel flow. I’m not sure if a standard ECU can handle E85, however I'm sure others can expand this point.

Pump E85 is not as of consistent quality as Drum E85 and therefore you need to have a safer tune if running Pump E85 if not and you get a ‘bad’ or low quality batch you could run your engine dangerously lean (if it was tuned on a high quality batch). The standard in Australia for Ethanol is 70-85% v/v http://www.environment.gov.au/atmosphere/fuelquality/standards/ethanol-e85.html#standard. You run the same risk if you tune on Drum E85 and then put pump E85 in. Some aftermarket ECUs have an ethanol sensor that constantly monitors the ethanol content of your fuel and adjusts the cars tune to suit.

The plan for my car is to use an ethanol sensor and have the car tuned first on 98 and then on pump E85 so that the car has 2 good base maps to work from. This way the sensor can linearly change the map accordingly.

On a positive for the environment, using E85 actually reduces emissions provided that if you are running an aftermarket ECU and it has been tuned to meet the emissions level for your vehicle.

The ms2 and a few other ECUs have the capability to be able to switch between e85 and 98 octane.

For me the car isn't a daily so it doesn't really bother me having to drive to fill up, just bring a few Jerry cans with you.

Yeah I have already purchased a new fuel pump the dw200 also some ev14 850cc injectors and leaning towards the ms2pnp as it has an input to run a flex sensor only thing left is weather I will need to do the fuel lines or if the can handle it short term
