Does any know of this works when the car is tuned in Speed Density?

 

Why would it not work? All it does is adjust fueling to account for increased ethanol percentage. Speed density is just a method of tuning fueling.

 

It works running a 43% ethanol equivalent to about 98-99 octane my steady mix is gonna be 15 gals e85 to 4 gals of 91,89 or 87 either way end result will be a 102-103 octane with 71.50 percent ethanol content that’s the lowest I could calculate content before dropping below 100 proof lol !

 

Are you running the pro flex commander? Does it actually work

 

I run Pro Flex Commander Pro they offer 2 Flavors !

Buddy have you ever heard a Euro Spec ? Love my alcohol burner ! It was done as well to reduce emissions! Gasoline stinks horribly ! Since e85 can’t smell notta ! So was it worth it ? can’t answer that

I have done what I wanted to do if that makes sense therefore I’m content with my decision!

The compression ratio is out of this world with my build and I prob turned a lot of heads pushing 40 mpg before on 91 and I’m still going to expect 37 mpg and a noticeable 80 horses off the rip and I haven’t even begun modifications to the modification! I wouldn’t expect the same gains as this car. most reported 40-50 from my finds N/A !


Its just my way of saying they did a good job putting modern tech available!


Nothing’s perfect that being said they sent me 2 fuel line with quick connect and release ! Good quality Each has 1 90degree elbow it made me go wtf lol . So I go it the lines in the 3/8 supply line off the firewall was S shaped not good ! Plus the fuel travel was going from 8 inches to over 20 ! Took a picture and took off the fuel lines and sensor ! Put back on the stock steel braided line with a dual female connection! Problem of long twisted lines solved !

I get they sent out lines so you could hook it up ! But for the price I would have honestly like to have seen the kit come fuel line specific . They have sent me a double female connection! Which Should look Nice !

 

Do you have dyno graphs you could post? Are you running E85 from the pump, or some other type of fuel? Are your fuel injectors near their max duty cycle with all the extra fuel required?
I really want to run E85, but they don't sell it in my area. I'm also curious if I could adjust my PCM tune via HPT instead of buying a proflex commander.

 

This ought to get the boys going !

 

I believe u still need the sensor u could reprogram but why and only run e85 or flash and re flash . Doesn’t make sense you’ll end up burning your pcm board ! Flashing should be done little as possible for longevity! Again I don’t dyno. I’m still yet to log the car again ! Maybe later I’ll have a look !

 

you can do this but you will need to run e85 all the time or ride around with your laptop and reflash different tunes according to ethanol/gas content... you can do this without the sensor as well, the only time you will need the sensor is if you do a flex setup or you want to monitor it on a gauge... if the content fluctuates your afr will change as well, in my experience a couple of percent in either direction won't be very significant but a big swing (say going from e85 to e60) then you will want to adjust your tune for that... basically it would be a pita to go back and forth between ethanol and gas without a flex setup but if you run it full time and watch the content you should be fine... the huge drawback from the proflex is that it has no ability to change ignition timing and that leaves a chunk of power on the table in a boosted application

 

So this measures the ethanol content and adjusts the injector pulsewidth accordingly?

Does it also adjust timing? If it doesn’t, I’d think you aren’t getting the full benefit of running E85

 

The tune will auto adjust for timing as e85 will not take as much advancement and doesn’t require it there’s just no need to mess with more adjustments and because of e85 lower knock there’s no need to adjust for that either . You can most likely further corrective tune e85 but it’s honestly going to a be big waste of time from my understanding! Especially if the car was tuned already on 91 to run some pretty nice advances e85 won’t and don’t need to advance it’s timing so much .

 

not trying to be a dick but this is all wrong... if you actually put your car on a dyno you would be able to see the gains, on the street your butt dyno may not be able to tell

 

I got my information from proflex themselves! But I’m not saying anyone is right or wrong here. The tech side I know exactly what proflex is and does it’s just like my Honda’s tuning kit runs a mirror emulator /virtual pc!

 

Why would I tune for e85 with a proflex it’s doing all the work for u ! I did tech code programming for years I am partially responsible for what android/open source Linux based is today if u feel me !

Please I would like to know about e85 advancement tables this morning while I am fresh ! I’ve never tuned a e85 just for e85 this why I ask !

 

100% inaccurate.

"Because of E85s increased resistance to detonation, it allows for more power without the cost of expensive race fuels." Increased resistance to detonation means you can increase timing. Increased timing means more power.

https://www.americanmuscle.com/pros-...ns-to-e85.html

"Practically speaking, E85 will help your car burn cleaner, run cooler and is essentially 105 octane fuel." Higher octane means increased resistance to detonation which, again, means you can increase timing. Increased timing means more power.

https://www.autoguide.com/auto-news/...-dynamics.html

"The ProFlex system utilizes a sensor that can tell exactly how much gas and ethanol is in your fuel. This information is fed to Advanced Fuel Dynamics’ patented Commander control module which modifies fuel delivery to maximize power and protect your engine no matter what blend you are running. From 100% gasoline to 100% ethanol, the Commander module utilizes their BlendSense™ infinitely variable fuel mapping technology to deliver the exact right amount of fuel to your injectors." Does not alter the timing.

 

If proflex inability to mirror the pcm it would not know the pcm settings if this makes sense! ( A ) file is it’s base it does make a new one every time u start the car because after u have changed fuel it compensates it’s self at your pcm! It let’s ( A ) run it’s course thinking it’s doing it’s job but really it’s not and ur Mirror is doing the work at the module . If your only modification is to pulse then the module only knows how much fuel to dump thus if this were true the car wouldn’t make any more power then what it did previously because it only compensated to produce the amount of fuel to power car was tuned at the pcm for ! Which I’ve seen and felt the gain now if the car doesn’t know how to use the e85 why is it we are making more power that’s clearly felt and heard . Again there’s more to ProFlex And people don’t often release the secret ingredients to cookies and such that’s why there’s a patent lol ! If this thing was less expensive I would buy one to to rig up to a pc and get a clear look at what’s happening at the module it’s self !

 

Just adding this to the conversation so this thread has some factual information from the manufacturer. DOES NOT ALTER TIMING MAP.

I should add that they are 100% incorrect about the timing tables of your pump gas tune being the "best" for E85 as that is just an asinine claim. The main benefit to running E85 is the ability to run increased timing and/or boost which is where the increased power comes from.

 

I still haven’t received the 3 inch quick connect they said they were gonna send !

 

Car purrs like a kitten on moonshine

 

According to the myth e85 doesn’t make more power after about 45-50% ethanol or the difference are so minuscule it didn’t really make sense to run it that high . Either way I run a a full batch corn fed
