The sensor is just a GM flex fuel sensor. Problem is they go bad very easily and are $$. Problem #2 is you can setup a user defined fuel trim with the flex fuel sensor but you can't setup an ignition trim (user defined) to take full advantage of it. Boost isn't that big of a deal but that would be a plus as well.

Are you talking from an AEM standpoint? IE the AEM wont allow user defined tables to switch timing? Is that for both the v1 and v2 boxes?

Yea AEM sorry about that. I was responding to the other guys post about it.

The v2 just uses different software, firmware, and hardware but the general map is still a v1.19 map which means the v1 and v2 have no definition changes. That is corrent the AEM does not have a table defined to allow the user to define ignition trims based on a sensor input. It shouldn't be something hard for AEM to implement so maybe I will send an email to my contact there and see if there is anything he can do.

John at The Shop is working with EcuTek (Racerom) to try and integrate an ethanol sensor just like that, but i dont think they have really started yet.

If you search for that sensor over on EvoM, those guys have been playing with them for quite a while....maybe they have figured it out already.
I spoke with an AEM tech and he was saying it’s possible to make an adapting map. Example: Your have a map for E85 but go to an area that doesn’t carry E85. You can then just put 91 in the tank and it will adjust accordingly to make the map safe to run. This can also be helpful in areas that have winter blends of E85, well technically E70 in the winter blend. He said to look at the “User Fuel Trim” table and have the E85 sensor provide input to that table. It will measure the ethanol percentage which even Cali 91 has 10% ethanol in it. The AEM Tech also said to look for another table “Boost WG Brao Trim” which can be also linked to react to the sensor. That is the table to electronically adjust boost via the sensors input. I forgot to ask and get the name of the table for timing but he did confirm you can control your timing also in the same manner.

Reason I also said 4 maps because we are looking to get 600+whp which you can’t really track that kind of power easily. We where planning on 2 maps for E85, power and track (450whp) and 2 maps for 91, power and track. With a map that can read your tank and adjust its map to fit your fuel, it will eliminate 2 maps by only needing track and power. If that makes any sense? I have heard from AEM and Full Race it is possible and I wanted to know if anyone has done it or did more research them myself.

I am going to nickname this a "Darwin" map, or even better, a "Carwin" map

I believe we have a V1 and curious if this will hinder my chances of an adaptable map? If so I should start looking to swap it out for a V2.

maybe a boring update to this thread but last tank again no trip over 5 miles, true suburb stop and go driving, air conditioning, I might not even break 55 mph on a tank a fuel, just trying to get people an idea of what economy would be on a daily driver short trip if you are considering converting.

15.14 mpg

thats really not bad. i boost around a bit around town and barely get 18-20 on 93. drove 4 hours on the highway last week picking up a set of bbs and got 320 out of a tank. more or less 80mph on the nj autobahn the whole way.

I get 300 out of mine on 93 with intake and exhaust. So that's not to bad. I drive the speed limit 80% of the time.

2nd and 3rd get a lil deep once in a while but i keep the speed limits in mind. i have never gotten a speedin ticket in my subaru. i have a passport x85 though...works well. in nj there is a cop every couple miles though, no jokes. i cant go 5 miles in any direction with seeing officer friendly. thats actually a good thing. atco raceway is 5 miles and millville is 50 minutes from my house for gettin on it.

So I am starting to tear down my motor tomorrow (Sunday). An allwheeljunkies member graciously loaned me his garage for a few weeks. Can you believe that? The subaru community surprises me once again with random acts of kindness like that. He is also helping me pull my motor (along with a few other awj subie members). To repay him, im giving him and engine hoist and stand.

Anyways, im buying a shortblock, turbo, injectors, and ecutek from another member as well. The price is right and im paying for it by vinyl wrapping a few cars for stupid cheap.

On topic, do any of you use the ecutek? Does it accommodate e85? Im learning about it slowly. How hard is tuning it? I wont be running e85 for a while, but I definitely plan to drink the forbidden fuel again

There is absolutely no reason to use the ecutek if u already have opensource. Opensource, access port and ecutek are just different graphical user interfaces. You are changing the exact same tables in the ecu with each interface. Tuning is exactly the same. And with the ecutek u can't tune it yourself unless that guy is giving you the delta dash with it.

One hand washes the other my brother...

As far as I know, only an ecutek licensed tuner can tune ecutek. Ecutek feels some sort of way about freeware, tactrix, ecuflash...trust me.

The east coast tuners love the new racerom software. I'm sure Ron will chime in on who can tune ecutek.

Congrats on being able to keep your Subaru and big up to the gentleman that are helping you.

Well hmm, it comes with the package. Not sure if it comes with the delta dash stuff. Ecutek's site seems a lot more user friendly.

Go into the engine management forum and read the 1 ecutek thread then you will understand

Will do. It just seems like it will add more complexity to my already frustration situation.

whats you guys' opinions on the turboxs utec? obviously, i am already opensource, and the car is running fine, but i have a guy willing to pretty much give me a utec. i already have the tuner pro that it could hook up to, but i was looking over the tuning and it looks like it might require quite a bit of retuning. an advantage looks like maybe being able to have different fueling and timing maps that i can switch to right there at the pump, and also, i have found mixed results as to whether or not it has low impedance injector drivers or if i would still need to use a resistor pack. basically, i am just trying to find out if it would be worth it to spend the time retuning mine, or if i would be better off letting someone else use it that hasn't already been tuned.

I have a UTEC. I used it when it was the only real option. There is a lot it can't do that OS can. There are some things it can do that OS can't. It's still in the car, but not connected anymore.

This is my opinion:

- I would not run UTEC unless you are very knowledgeable about troubleshooting. A UTEC does not have any kind of safe mode or IAM type protection. If your car has any problem, it will be unusable until you re-program the UTEC to adapt to the problem or fix the problem.

- I would not run a UTEC on a pump gas car. I did for a while when it was a better option than using a UNICHIP. The knock protection scheme is not as good as the stock ECU, IMO. Somewhat related to the previous point, I suppose. This is the E85 thread, and E85 is a LOT easier to tune with and has way more margin for error. It's well suited for that.

- The tuning tools available for UTEC are all like the OS user tools (user created tuning aides like Airboy spreadsheet and Bad Noodle MAF scaling sheet) There are no professional tools to help you with tuning. IMO the tuning tools for OS are better. The logging interface is higher baud rate, but highly limited and not user configurable. There are a very limited number of logging profiles for SD, you use one of the existing logging profiles. This is a significant downside in my opinion. Logging is somewhat of a pain.

- SD mode UTEC + E85 is actually pretty good. Using the UTEC with E85 or race gas is where it shines. The tuning on high octane fuel is much easier, so the lack of tools / logging is not such a major downside. There is usually margin on the knock threshold, so the issues there are not a big deal either. Note that some people want to run SD fueling in the UTEC and timing via the ECU (people who want to retain the stock style timing / knock safeguards for pump gas)...this is not possible because the UTEC feeds the ECU bogus MAF data when it runs SD.

If you pick up a UTEC, I think the best way to use it to switch between pump and E85 is to use the stock ECU for pump (and set the UTEC to passthrough / Map 0) and the UTEC maps for E85.

Like others have said Ecutek has no end user tuning right now.

Standard Ecutek vs open source are all very similar

EcuTek has maps open source doesn't have which is cool sometimes, but really nothing too special. As a protuner Ecutek comes in handy when a new car/ecu comes out and no one has support for it.

Cobb is now good with that as well with the new ecu dump feature built into the accessports

Now racerom is a completely different story. Dual maps on the fly SD, per gear fueling, per gear timing comp and other things. But only protuners can tune with it, so if you want to tinker with your car forget about it.

Basically if your a selftuner I would buy a cobb ap. Cobb is going to have some really really cool stuff soon

If by self tuner you mean I have the dark wizard mikey do everything, yes I am

Just kidding, ill stick with open source and keep having mikey tune my car. His level of professionalism amazes me and I will always refer my friends to him and Ron. I hope one day I can be as educated as those guys! Not to steal business, but to be self sufficient for once

8.99@160mph on the corn! Still got another 10psi left to go too.. Think we are going to move to some e98 on the bigger boost.
