AFD ProFlex E85 Commander Journey w/ GT350

[lightrules]

Google the YouTube video on the proflex Commander and Bluetooth connection. you have to go to your phone and allow location permissions on within the app. also you cannot check ethanol content with a car running, they're trying to make that fix right now but all you can do is check ethanol content with the power on but engine off

nvm

I'm on a sct 93 preload tune, the car runs pretty much exactly the same on 93 but I feel like it makes a little less power on the bottom end, and slightly worse idle, but may be placebo. Gonna try some alcohol next.

68%, it's running pretty smooth, I haven't tried getting on it yet. It's been raining and insanely humid. Success so far..

 

[mmakam2]

any guesses on power over baseline?? I'm going to try and get on the dyno next week. One with stock tune, one on SCT preload

 

[lightrules]

those of you running e85, do you notice more backfiring and popping over 91 or 93 octane? it's something i am noticing with the proflex+e85. just wondering if it's just my imagination or if there is something to it.

just went for a little rip, I think I noticed that too. it kind of makes sense based on how the system works. it's still putting in 20% more fuel (or whatever) on decel over what the PCM wants. Sounds badass if you ask me.

The car is most definitely making more power, especially in the midrange. It also seems like it's running cooler based on oil and head Temps, and it also feels just way more smooth like a great NA pump gas tune would. Under like 2500rpm tho it feels little more sluggish than it used to, possibly too much fuel. Or it may be more of a transient throttle issue because I kind of notice a bit of lag when punching the throttle also.

Need to try the stock tune to compare also, maybe an artifact of stacking the sct preload with the AFD. Most definitely still very well mannered and drive able, it's barely a complaint.

BTW this is on E68

yeah everything you wrote is what i am experiencing too. not sure if it's in my head, but it does seem a tad more sluggish on the lower rpms but feels great higher up. regarding the intensified/more frequent backfiring, so long as it isnt hurting anything, i am good with it.

I'll give Gray a call on Friday to see what he thinks. All in all I'm happy with the result if this is it.

has room for improvement, wish there was some adjustability to the fuel maps. Maybe they will give us some updates over Bluetooth one day..

fyi I mounted my unit on top of my antigravity lithium battery. Keeps it enclosed and cooler hopefully. Made for a pretty clean install.

I'll chime in with my experience with the ProFlex Commander over the past year and a half that I have had it. Love the unit; no issues at all with connectivity in reading the ethanol percentage real time while driving. Power increase over 93 octane is NOT a placebo effect; it is real! I want you guys to drive it for some time to give your feedback on the unit and get your Dyno results. Unfortunately I did not do a pre and post Dyno but really interested in you guys results like Sasha posted.

We aren't saying we aren't making power. We are DEFINITELY making power in mid and high rpm range. We are debating the lugging in very low rpms if that is the kit or not. Mine is not reading content real time either, only when on but not running.

Side note for those who think ethanol is corrosive to engines. Methanol is corrosive, which is why ethanol probably gets a bad rep as an alcohol fuel.

maybe you are using apple? i know with android there is an issue with reading real time engine running e%. i can only do it with power on, engine off. gray @ AFD is very aware of this problem and wrote this today to me: "I have a new Commander with a more robust signal going out to one of our Tuners for testing to see if we can get past Ford’s signal killer. As soon as I hear the results I will let you know."

anyway not sure if it's an apple/android issue or what. sounds like from gray's reply to me that it is a ford signal issue. anyway hope they get this fixed up, would love to see ethanol content with engine running/driving.

as for performance, i need more time with the kit. so far so good though. thanks for your thoughts, it's good to hear.

 

[Mjc1241]

I have Android so maybe it's because I have one of the early units and/or I have a 2016? Not sure. Mine reads fine. Hope that they get it sorted out for you guys. Next time I fill up with E85 I will see if I have the low RPM lugging and let you guys know. I also do the three tanks of 93 for every one tank of E85 so it's been a month or so since my last switch.

 

[lightrules]

@Mjc1241 , yeah maybe earlier shelbys are immune to the issue? hopefully we'll get more info soon.

again, the low rpm range could just be in my head, for all i know. i just need more time with the car and proflex. it isn't a significant issue, if at all.

also, any known reason why we shouldnt go e85 full tank indefinitely? i was planning to go e85 here in so-Cal for the summer months, and then when it gets colder throw some 91 octane back in. i'll do what's best for the car though ultimately. let me know.

 

[Mjc1241]

Since E85 is hydroscopic, I just run 93 for peace of mind. I assume nothing wrong with running e85 full-time, I just personally don't because my car sits for a few days at a time between drives. Two and two is probably a better compromise but there was a few times last year when it was a week or two between drives due to weather. By the way, it runs like a scalded rat on E85 above 4k rpm!!!
