ECUtek Flex Fuel REVOLUTION: World's First Flex Fuel Factory ECU GTR - BRZ soon!

[ML]

can you run other fuels besides pump and ethanol?

[Cheddar]

I dont really understand what this is doing. Is this something to make the system completely E85 compatable?

Or is it something to run E85 on a daily bases?

Or its a E85/93 system that changes on the fly depending whats in the tank?

There is already an E85 map if you want to run just E85. What is happening now is Flex Fuel which uses a sensor to detect the amount of ethanol content in the fuel and adjust mapping on the fly so that you no longer have to load up different maps. So, for example, whereas you have to run the tank almost dry before switching from E85 to 91/93 or vice-versa, with the flex fuel tune and kit, you can just fill up with whatever you want whenever and it will adjust accordingly.

Ah this is what l was waiting on!

Also comes in real handy when your station changes the E85 mix down to E70 for winter. No need to retune for lower ethanol content.

arent you supposed to turn off your engine when you pump any kind of fuel for safety reasons? hmm

I think its kind of obvious John filled up with the engine on so everyone could see the ethanol content meter change while he was filling up...

The way its setup right now, you have two maps. One 93 and one E85. To run either of them you have to run out your tank as much as possible and switch maps.

With this Kit, you can have your tank half full with 93 and decide you want to fill up with E85 and it will be ok, becuase the sensor will calculate the amount of Ethanol content present in the gas (in this example lets say it is E40 because of the 93) and the same map will adjust to whatever ethanol content you have on the tank, and maximize performance for this content. So, instead of having two different maps for 93 and E85, you now have one map that works with 93, and E0 to E99.

I see what you mean. But if E85 is cheaper why would anyone want to go back to 93?

I understand you need to put more E85 into the camber to make power but how about a system that lets your run E85 with and get the same MPG as 93 and when you want to get down with the get down it changes.

idk if that makes any sense to anyone but i hope you know what i mean.

One example: Some people don't have E85 near, so they decide to run E85, do a 50 mile trip to get it. Then at 1/4 tank they decide they want more gas. At this moment they don't need to run the tank out if E85 and do not need to do the 50 mile trip to get more E85. They can just fill with 93 and the sensor will take care of the rest.

Second example, out of nowhere you get an invitation for track day tomorrow and you want to run E85 but unfortunately you are half a tank of 93. Presently, you are out of luck, you have to run the tank out and refill E85 or give up the idea and run 93. With this kit, you can get at least part of the E85 performance improvement benefit and get certain percentage ethanol which will be better than a 93 fill.

Also, for some people that don't drive their car every day, it can be a bit of a concern leaving ethanol in the gas tank sitting for days because moisture can build up. With this kit, I can fill 1/2 with ethanol, use it for track day and then if at the end of the day I know the car is going to be sitting for a week I go ahead and fill it out with 93 and don't mind the amount of Ethanol that was left.....

Its just a matter of expanding in the goods that we already have.

Lastly, a kit that will make E85 have the same MPG than 93 (like switch to a map that allows that) I think would mean you would be making less power than the stock car, so in that case it is better to have two maps to switch to, one 93 and one E85... But again, this solves it all!

^ very good points!

Thx

Just what I've been waiting for since E85 is available to me, but not real convenient to get to. This is badass!
