With the 93 tune the BOV, turbo whistle and exhaust purr are more pronounced. Is that normal?

Yes, many people have in addition reported hearing a "honk"/duck call type sound with the 4X tune, also with Unleashed's hotter tunes.

I don't believe there is a "trade-in" program, but you have to PM Torrie directly or ask in his subforum (PM is quicker, I think).  In any case, you should ask LME to see if they will give you a tune for the effective octane you are running.  They will be understandably reluctant as they don't endorse fuel additives in the first place (at least for the EB platform).  Call them or PM them or ask the question in their subforum.

What is your goal anyway with the race gas tune?  It certainly wouldn't be a DD tune, and it would be an unknown what if anything, it means for the powertrain in this case.
 
Very interesting info. Clearly the experiment impressed you a lot... I'd be really interested to see the KR numbers on stock vs 91 4x vs 93 4x...dyno and real world would be interesting too...and comparing I'd also be interested in the numbers on winter blend oxygenated gas vs summer blend. Did you run 91 vs 93 octane tunes for your impressions? I have the same problem in AZ .... Stuck with 91 octane at the pump. If it all looks safe in the OBD monitoring it could be a true boon. I have been holding off on the ACES products for this kind of info. As far as the tune, your choice... But if the numbers pan out I'd this could be the reason for me to pull the trigger on ACES since I'm personally not into tune tweaking...due to my laziness... So I'd love it to make an LME tune as strong as this seems to be for you by running 93 v8 instead of 91 v8.
 
Well I will be trying to figure out the KR pid later today. Going on my "workout" now.

But No I do not have an "extra" $400 laying around but I thought Torrie used the MyCal as well. So how would I get an effective octane rating number to give to LMS for them to modify the tune? And then what exactly would I need to monitor to show that everything is working safely?

As for goals of using racing formula, like you Tom I don't like any mod or add on to look like an add on. Which is partially why I will be dumping the Airraid CAI in the coming months. Just have to dig the factory intake out of the shed. But If I can add the racing formula of ACES, I get a modified tune to take advantage of it then seems my car could be at 450-475 hp with no meth. Detune it a bit for daily driving since that is how car is driven. Not a track car but would love to have track performance on tap. Thus far, I am HAPPY with the 93 tune. I want/need to get the info to verify all is good. But doesn't appear to pulling timing, no knocking or pinging, instant throttle response. So if you only have access to 91 octane my preliminary reports are you are safe to use the 93 octane tune by using the ACES IV. Just my non scientific observation.
 
Unleashed = SCT, LME = MyCal

You can guesstimate effective octane using info from Brian/BND, then ask for a tune for gas a couple of octane points lower, to give yourself headroom.

But getting yourself setup with Forscan on iDevice or Forscan/Torque Pro on Android is the way most of us datalog currently.  ecoboostsho's hard work with Torque PIDs comes in real handy.
 
The obd readers from ?????? caused a bunch of errors in dash readings before. So I won't be using anymore of those.

Tom since you only have 91 octane too, and you probably already do some data logging are you willing to load to 93 tune and log it? You won't be disappointed I a can assure you.

You could probably get log results faster than me. I gotta figure out why mine isn't reading. I am returning the mx for replacement to see if I just got a lemon.
 
My experience with ACES IV:

2 fill up on the SHO, not much to report, I probably have to reset the computer or re-tune to benefit.

3 fill up on the WRX and WOW! It's a 2L engine with a 20G turbo so low RPM was pretty dead on torque but since running ACES IV, the part throotle low RPM "get up and go" is much MUCH improve. Turbo is faster to respond and the tail pipe seems to be cleaning itself. This is all happening in the "close loop" part of the tune, where variable valves timing is in use. When going WOT or higher boost "open loop" tune, not much has changed. So a dyno re-tune for the open-loop should help benefits from the ACES IV, I guess. But at a 10.8 AFR, the tune is too rich anyway.

Running Petro-Canada 94 octane in both cars.

EDIT: forgot to say, the WRX engine is running smoother too. It was already a happy reving well balanced motor (EJ207) so I am impressed!
 
Im still trying to get a good read from my obd reader. In a nutshell, if you have Android go bluetooth, if iPhone then WiFi. I chose the WiFi option as I will be dumping my Android soon. Piece of crap in my opinion. But when the reader stay connected, all my readings are good. I think. I reloaded the 91 4plus tune so thats what this is showing.

My last readings with the 93 tune were similar. But in both occasions, the LOR/OAR number does drift a bit. I started at -.7 and within couple miles car was at -1.0 on to -1.2.

I will reload the 93 tune and recheck. In speaking with Brian about the race formula of ACES, his thoughts were I need more time for the ACES IV to become fully impactful. I may also up the ratio to 1:5 for a couple tanks with the 93 tune loaded.

Does anyone with iPad/Iphone have the Ford PID's purchased in DashCommand? Been writing them and I am having issues with their policies. Buy app for $10, then buy manufacturer specify year ($10). But you can't use that for ANY other year. So for me, I have 4 cars. Would cost me $50 total to have PID's for all cars. And if I change cars, all this is out the door and have to buy another module for year of specific vehicle. Are there any other working options for IOS?

This was during normal acceleration. There is thread or post elsewhere on this board about the LOR going beyond -1.0. No real plausible explanation. One could set the MAX reading to be -1 and make it all look good. I think the jury is still out on EXACTLY how to interpret the LOR/OAR.

On your recommendation I reloaded the 91 tune and am getting similar numbers vs the 93 tune. But again, my WiFi and Android obd drops connection so I can't do a data log event. Unless there is a way to do it on iPad without breaking the bank.
 
If you think torque is operating correctly, I would TRY the 93 tune but I would watch OAR and KR. If OAR stays at -1 and KR is good then I wouldn't be concerned at all.

I suspect you are fine with my ACES experiences so far. At the same time I would never suggest shenanigans without some sort of reliable monitoring.

I am comfortable with Cobb and Stratifieds explanation of OAR and they match up with my real world experiences. 

 
A commment you made about possibly not enough octane when -.7 was showing was why I reloaded 91 tune. But with 91 and 93 tunes the LOR never goes higher than -.7 but has gone to -1.0 on 93 tune and -1.2 on 91 tune. Also, I have very little info to work with on the knock sensors raw data and its use and meaning. Those numbers are all over the place so I have no clue how to interpret.

And like you, using the ACES I am NOT seeing any negative performance. No pinging, stutters, flat spots or anything. Just rock solid performance. Just with my tools I cannot scientifically quantify it reliably.

But I love the 93 tune performance over the 91. Just the fans stay on ALL the time. So I may opt for the colder 160 thermostat to help. I think the 93 tune wants everything cooler. I currently have the 170.

P.S.
I see team ACES in your signature. Any explanation? Or are you and I the early users of the ACES?

Well, if you are changing or adding something to the fuel, seeing a blip in OAR isn't unexpected. If it didn't move back to -1 I'd start to think my tune was a little hot for the available octane. That being said, I haven't  seen anything but -1 except 0n the 2015 when it had 87 in the tank to start.

Your 170 should be fine I think they can fix that fan issue in the tune, I feel like others have had the same issue, but that could be incorrect as well.

Yeah on the ACES, us and a couple others being the first guinea pigs.

Screenshot attached of current brew of ACES and an E20 Torrie tune no revisions....yet.

Those max#'s are from a WOT pull just into 3rd.

I'd like to seen your raw knock and KR from a WOT pull as I'm trying to figure it out. I think SHOdded pointed me in the right direction. Each gear has a different threshold but that is after the ECM analyzes and filters the raw data and adjusts based on a noise threshold to eliminate false knock. That being said for WOT numbers a lower max starting point should be better.

 
That was at idle.

While driving they are all hover around ZERO so the blend matches my tune nicely.

A couple of things....

My tune is for E20 so lambda in my tune is 13.51:1

Also, one of the claims is the ACES gets more work out of the same fuel so you need less fuel to hit the same AFR. When I was on a straight 93 tune, the trims also went negative so I believe the claim is valid.

Notice that bitchin FRP? So far I've seen zero FRP degradation and I think the ACES helps with fuel volume....Still hits over 2700PSI at times. Once again more work equals less fuel needed so my injectors aren't taxed and I can maintain high pressure even with the corn, at least that's my theory, lol.

 
As soon as I dump the droid, I should be able to log better Im hoping. Unless I spring for additional bluetooth reader. Which doesn't make me to happy!

Seems like the ACES is the real deal. Once I can reliably log everything, I will be stepping down from 91 octane gas I buy to 89. That SHOULD keep me in range and save me a few bucks at the same time
 
Reloaded the 93 tune. This is what I am seeing. There weren't any WOT runs but pretty aggressive to about 90 mph.

So with a -4 KR wouldn't that indicate the fuel is great for the tune loaded with plenty of room for more aggression?
