Best tune for 2020 Ford Explorer ST

Also interested in this..
I never run less than 93 in mine but From what I understand the Auto octane tune will learn up to E30, and that would be awesome. Be able to add a little E85 (when available) to a tank of 93 and see some gains.

Didn't know there were more out there that do the adjustable tune and are recommended for the ST. Would you say the tune is on par with ZFG or Monster?

Have you done any Dragy run before and after the tune?

I have an SCT X4 that I used on my 2 previous Explorer Sports. Would I be able to use it with the GearHead tune? I've read that transmission tuning with the X4 isn't nearly as good from what ZFG uses.

ZFG's 91/93 tunes will also accept up to an E30 mix. Since so many claim that their tunes will take an E30 mix, I wouldn't be surprised if FORD made the ST's E30 capable from the factory and the tuners are just taking advantage of that.

Anyone tried the ZFG auto octane tune? Can't seem to find any reviews of the auto octane tune. Any insight or just go with dedicated 93 tune n make sure the wife puts the right gas in at fill ups? Wife mostly drives it. Reason I was thinking of the auto octane tune is if 93 octane sky rockets again which I'm sure is around the corner I can throw 87 in n not worry about it and still feel a difference with trans tuning n slight performance bump over stock.

Debating on that or the Monster Tuned Auto-X tune. A few people say they are impressed with the tune. Seems they are very responsive and customer service is top notch. Anyone with their tune have any complaints or positive things to say after having the tune awhile now. Any Dragy results on it with different octanes?

Is the ZFG auto octane tune worth $200 over the Monster Tuned Auto-X?

I have the auto oct tune from ZFG. Completely satisfied. I'm not a techie but have found the TDN system easy to use. I will admit there is some anxiety when you hit the "write" button to load the tune. Tune delivered what Adam promises, he responds to questions and the shifting alone is worth the money, the extra 75 WHP is just a bonus. I did not have ZFG do any of the showing of gear all the time, or auto start/stop disable stuff, I have the auto stop/start Elimenator for that. Whipple IC, Steeda all around inc tower brace. Don't race it, no Draggy bragging rights, just a stupid smile on my face when I have open road to let her stretch her legs.

You could order up both an AO tune and a PE30 tune for less than the ZFG tune, since you have the X4 already. I’m using an X4 to load up my Gearhead tunes. I haven’t run the ZFG tune, so can’t personally comment on their comparison. I will say that after data logging 91, 94 and E30 on the GearHead AO tune didn’t need a single revision. It’s also within a 10th in the 1/4 of the BoostKing and Unleashed dedicated tunes when comparing on 94 octane. Like I said above, VERY impressed.

I do also have tunes from BoostKing and Unleashed that are dedicated octane tunes (91 and 94 with each tuner). I really like my BK tune as it has a more aggressive toe in and the shifting is nice and sporty, even in normal mode. The Unleashed tune is similar, but pushes the turbos a little harder up top. I use my MPVI2 to load these tunes, but they are both able to also tune on SCT.

All three of these tuners have tuned my extensively modified 3.5 F150 and have been in eco game for a long time. I would recommend BK if you want a dedicated octane tune and GearHead if you’re looking for an AO tune.

Lots of great options on this platform!

Thanks. Used Unleashed for my 2 previous Explorer Sports but thought the SCT X4 was outdated for this application so I looked elsewhere and at the HP tuners device thinking it was my only option.

Appreciate your help guys

Nobody with the monster x tune has posted any times, so hard to really make a concrete conclusion. Having run ZFG I would say absolutely worth the extra money. I would advise going with the auto octane tune if someone else is putting gas in it. Better safe than sorry.


I went with Gearhead AO tune when I bought my ST because I had used them for years with my SHO, and I already had the SCT device. AO tune was $150 last time I checked, but I bought that and an E30 tune at same time for $250.

Everything else stock, AO tune ran 12.43 (dragy) best in perfect air. I added intercooler and AFE intake at same time I switched over to the E30 tune, best time I saw at track was 11.997. Best dragy on mexican streets I ever got was 12.01.

If you aren't looking for every last tenth, gearhead is great and easy to use. I am looking for every last tenth, so in May of this year I got a ZFG E50 tune. One revision and it ran 11.82 on the tough mexican streets. There's a good reason there's a flood of people saying ZFG every time someone asks which tune they should use.

I'd love to see some dragy or track slips from other tuners, but usually all you get are butt dyno reports.

How was the transmission tuning with the GearHead AO tune? Would you say the tune was good overall or any complaints with it?

Thanks

Much smoother than stock. Honestly loved the tune, only reason I tried ZFG was to shut up all the people that kept commenting "switch to zfg if you want to go quicker" on my youtube videos. Turned out they were actually right this time.

I run the ZFG E50 tune 95% of the time, but if I go on a long trip somewhere and can't find ethanol I switch over to the gearhead auto octane tune.

I really like the Gearhead shifting. It’s smooth but still nice and quick. They ramp up nicely as you increase throttle. Gearhead is known for spending a lot of time on refining the shift strategy. I like my BoostKing shifting as well, but it is more “sporty” and they are more noticeable even in normal mode. Gives you a bit of a different driving experience without having to go to sport mode all the time.

interesting. I may throw few gallons of E85 in my 3/4 full tank of 93 and see if i can feel a difference.

If you just throw a few gallons in it and run a Dragy for example, you're going to be disappointed. The ST doesn't have a real-time ethanol sensor. The ECU can quickly adjust the AFR via the wide-band O2 sensors, to adjust for ethanol for stoichiometric, but it also needs EGO to try to sense the amount of ethanol in the fuel which takes longer. It's also factoring in short and long-term trims. Nearly all manufacturers since 2016 will adapt to an E30 mix without any problems. (There's an IEEE paper on this).

However- it just cannot immediately adjust boost and timing to take advantage. If you listen to certain tuners, they would lead you to believe that you can do exactly what you mention- just dump in ethanol and you magically gain 50 hp. All of these tuners talking about automatic tuning don't seem to mention that the ethanol content sensing is already in place in the programming. They can take advantage of certain control strategies, but it isn't their magic.

I went to the dragstrip yesterday. The ST had 93 in the tank. I did 2 1/4 mile passes. Both were almost identical. 13.80 at 99 mph. I put in the 5 star 93 performance tune and raced the rest of the night with it. Best times consistently at 13.24, 13.23 at 102.xx. I could not get it any faster. My 60 foot at 1.87 best. Launched at about 2,500-2,800 rpm.
