Tuning with minimal upgrades

[glock-coma]

I think they can see only see that ecu information has recently been accessed and how many times. but many different things can cause that.  The torque app with the mx adapter, Sct x4 used as gauges, code scan at autozone, e-check, Dead battery, KAM reset. Basically anything that pulls info from the ecu via the obd2 port.
If they dig deeper I believe they can see other parameters but I'm not sure which ones.

I wanted to take a second to give a little update on my now-tuned 2015 Explorer Sport.  It has been a couple weeks since I installed new plugs and a K&N drop-in filter, and up to this point I have run the LMS 91 and 93 performance tunes.  To begin, the difference between stock and the 91 tune is definitely noticeable.  The shifts are firmer and take place at higher RPMs.  The car takes off a little bit faster, and I really notice the power when stepping on the gas at highway speeds. Other than that, I did a 500-mile road trip and did actually notice about a .5 mpg difference with this tune.  Anything helps, I guess.  After first installing, it did take a couple days of driving to soften up the shifts, like several of you noted.

Concerning the 93 tune, I honestly did not notice much difference over the 91, which kind of surprised me.  93 octane fuel is very easy for me to find in FL, and my original plan was to run this 93 tune for the long run, thinking it would deliver the best performance.  However, after driving each tune for one week, I think I prefer the 91 tune.  I can't exactly put my finger on why, but the car seems to be a bit more drivable and the difference in power is negligible.  What gives?  I haven't had the chance to drive the 93 tune on the highway, but maybe thats where it would really shine.  Any thoughts on this?  Should I give the 93 another chance?

On a side note, I took the car to Ford for an oil change today (after flashing to stock the day before).  I got the opportunity to speak to the tech while he was working on it, and without being asked, he told me that he saw that it had been "chipped."  He didn't seem to care, and I didn't really push him or ask any questions.  I figured I should share that information in case anyone is under the mistaken impression that a simple flash to stock will make the tune invisible to Ford.

He was fishing.

Personally, I wouldn't let anyone that used the term "chipped" within 10 feet of my vehicle.

They don't randomly plug the car into IDS for an oil change.

I would've challenged his presumption.

I was actually laughing at the use of the word "chipped"...its so outdated and inaccurate today

"chipped"

Maybe he was talking about the paint? Haha

Did he drop a wrench on it while he was working on it, hence "recently chipped"?

Any input on the LMS 91 v. 93 performance tunes?

I know you claimed 93 octane gasoline is easy to find above but are you using a top tier gas stations such as Shell,BP,Chevron,preferably at a busy station to be more ideal. Z

Yes, always fueling up at Shell.

If you have been switching between two tunes for a short period of time would try letting the fuel trims to adjust accordingly before switching between tunes.  Z
AFAIK negligible gains will be had between 91 & 93 octane.

I think I am going to remove my MDesign CAI.

Any particular reason why you thought about removing this CAI, if you don't mind me asking. If removed, would you think about selling.

 

[SHOdded]

I would advise that you work it out with anyone reselling the MDesign CAI to hlp with "warranty" service.  Unkess yiu are a fabricator you might be SOL if you need replacement parts.  Can you tell I am upset??? LOL

IsFox86, are you driving this thing with traction control enabled?  If so, do the 13 button clicks it takes to go into the menu and turn off traction control and trailer sway control.  I read in one of your earlier posts that the LMS tune only takes off a "little" quicker than stock.  My AJP Tune, which I am extremely happy with, takes off WAY quicker than stock.  The power comes in much quicker, like immediately off the line.  Stock, it sucked off the line.  You could tell it wasn't getting WOT off the line and much boost with the stock tune.  Stock, it doesn't really take off until you are up to around 20mph.  My 60ft times at the track went from a best of 2.194 seconds stock to 1.958 seconds.  This is huge and is on a 91 octane tune.  My wife even had it spinning the front tires for the first 5 feet at the track with my first really moderate tune.  It would spin a little before getting the power to the rear.  It never did that stock.  With that said, it doesn't take off nearly as quick with the tune if traction control is turned on.  Turn it off and then you'll feel a difference.  I have a hard time believing that the LMS tune is only a little quicker off the line.  The sluggish launch was definitely my biggest complaint about the Explorer stock and the tune rectified that for sure, but you have to turn off traction control to really feel it.

I have another tune to try but I picked the wrong spot to datalog 5 months ago and I am waiting to test it at the track now after spending $450 on a ticket!  It ran 14.54 stock and 13.81 tuned.  It also picked up 4mph.  Soon I'll be asking AJP for a hotter tune.  I really want 13.5 @ 100mph.  The current tune would probably do it if I ran it on a cold day.  I was not able to get out there when the air was cold.  I only ran it one night tuned and it was Extremely consistent compared to stock.  I won runner up that night.  I broke my collar bone 6 weeks ago and went back in a sling, after just getting out of a sling 5 months ago from shoulder surgery on the other side.  Anyway, I hope to get the Ex back out to the track soon and get some logs and then turn it up a little.  I am definitely happy with the performance daily driving.  He didn't make any shift point changes.  I might ask him about that too.  The only thing I don't like about the stock shift points is how quickly it gets to 3rd and always seems to lock the converter just as I am rolling on the throttle in 3rd and wanting to feel it pull.  It still pulls, but it messes with the senses to roll into it and hear the rpms drop as the converter locks eventhough you are accelerating.  Not a big deal, just the one spot that could use shifting improvement.  This is just unchanged from the stock tune.
