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

FT86 Community, I know my presents has been lacking this board recently but I've been very busy ! Last week was a very special week, as ECUTek unveils the world's first Flex Fuel Factory ECU GTR. Myself along with a few others - Bill @ Spray it Racing, and LitchField Performance have contributed to this project. While we are still several weeks away from this being available in the retail market, due to the required components still being arranged for mass sell....I wanted to provide some insight into one of the capabilities ECUtek has in store for 2013.

Here's a sneak

I've spent the last several weeks getting this new Flex Fuel Kit and Custom ECU maps working on the GTR. With the addition of new compensation maps that EcuTek has added I'll be able to do the same thing to the BRZ.

too soon to give a ballpark price?

I'm in the process of building the kits right now.

I'll have a better idea next week.

-John

Sounds good. I'll be following closely!

Very nice. Expect same results as the 93 map when pure 93 and well as same results as E85 map once the tank is complete E85?

This is going to be great, E85 is awesome but i feel the mixtures sold to us almost require a real flex fuel capability that this offers to take full advantage. Can't wait to see results.

Yes, I have a bunch of different maps setup to compensate for fueling timing.. and for those turbo cars - boost !

This is a real flex fuel capability.

Take a look at my youtube video.

I have a ethanol content sensor wired into the GTR ecu..

The ECU will know your exact ethanol content and my tuning will be compensated based on that content - just like I would do with a flash except its on-the-fly

-John

I understand it changes based on the amount of ethanol but I mean when pure one way or another. Just wasnt sure if it was more conservative and the extreme ends but I'm gathering that it is the same.

Also, what pure 93 octane? When I visit Tail of the Dragon, there is a place where I get stuck filling often it E0/93. Will this be safe with that?

Yes it'll be safe for E0 91/93

-John

This is awesome, and will be the option I need to pull the trigger on a full setup.

Updated first post with more videos of some of my work

Do we need to purchase a separate tune for flex fuel if we already have your e85 tune or do we just purchase the flex fuel kit from you.

If you have my tunes and kit your all set.

Remember I update all my tunes :)

can you run other fuels besides pump and ethanol?

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...

:sigh:

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.

What you said !

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

Bravo

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

From what I've experienced in my old car and what other's have seen E85 gas reduces your fuel efficiency by 4-5mpg in daily driving applications. Even though it's cheaper by a considerable amount you'll send up paying just a little more (few hundred a year) compared to premium.

Correct on the gas mileage aspect, but more importantly for most people who want to run it, it adds power. E85 having a high octane rating, tuned, equals faster racecar.

How granular is the sliding "on the fly" tuning? Is there essentially no reason to run a 93 map any more? Will the tune for e85 accommodate anything from E10 up to E85 on the fly?

Also, for those asking about why not run e85 because it's cheaper, it also equals 30% less fuel economy. 30mpg on 93 becomes 20mpg on e85, roughly, so there's not really a $$ savings at all, just a big power enhancement with the cost per mile being roughly equivalent.

My SRT-4 is running an e85 tune, getting about 16mpg. Before, on my 93 tune, it was good for 22-24mpg.

Yeah, that's the point of Flexfuel, it covers from 93 to E85 in one single map

Very nice, I misread your post on the first page and thought you were describing this setup as having two maps.

Sounds great, true flexfuel capability, fantastic!

This is gonna be awesome.

Is this going to to be a third map purchase option or is it a direct replacement for those who own both pumpgas and e85 (assuming they buy the kit?)

In other words, those who own both maps today, is this a free map replacing both? For those with only one, do they pay another 350? And those who have neither, is it 700 total for the flex map?

I realize the sensor kit itself will have an additional cost, I'm just asking about the map itself.

No third map

If you have my pump and e85 map all you need is my kit

John

Thanks, so those of us who only have pump or only have E85 right now, we'll pay another $350 to get the flex map, and however much the sensors cost?

Obviously this will increase reliability and help thwart some starting issues, which is fantastic itself.

I am curious though, given the flexibility of a precise content figure if you can afford to be less conservative with the tuning? Translated; any chance to see an increase in power numbers if using the kit?

I dont think there anymore more power to be had...

That being said if you ethanol content isn't 85% - lets say 75-80% you'll be down on power.

This kit will be able to compensate for the difference always giving you the best power

-John

Since there will constantly be different ethanol contents in the gas tank how will we know how much power we are making at the moment, and can you adjust boost on the fly and have it be safe to more ethanol being utilized?
