So at 87oct this tune will basically be identical to the stock tune performance wise? Is there anything different when using 87?
On 87 octane you'll be 10-15 hp over stock, but nothing crazy as you're limited by fuel quality. 10-15 hp will be hard to feel in a 4,700 lbs suv

Thanks for the quick response. Yeah I couldn't feel any difference between 87 and 93. I switched over to 87 and abandoned the idea of tuning after the gas skyrocketed lol. Gas has come down a bit and was thinking of tuning again. Do you only offer the autox tune or a dedicated 93 tune too? If you offer a 93 tune would you say the dedicated 93 tune provides more power over the adjustable one?

Only Adapt-X, there is nothing to gain with a straight 93 tune, our Adapt-X gets the most power the fuel is capable of. The OEM difference between 87-93 is about 35 hp because ford limits the power which is why tuning increases power, and additionally it takes 2 tanks to get the 87 out so it probably blended to like 90 octane, and even then the octane adjustment takes time it's not immediate.

I assume even though you state it is not immediate, it is quite quick at adjusting and it is still immediately safe to hammer on if you want to because it's always adjusting as knock is sensed?

Do you have any dyno results for this tune? Just curious. Does it flatten the curves at all, and is the HP gain decently significant across the entire curve?

Thanks! I'm getting more and more curious and interested in this tune.

If you're going from 93 to 87, I wouldn't just hammer it, that's not even our tune, oem is the same, it takes 15 minutes of driving for fuel to mix and then maybe another 10 minutes for octane to fully adjust.

I don't have any dyno results for sharing, testing was done on a mainline hub dynometer for development but we don't usually post graphs because a dyno is a tool to measure from a baseline number so comparing numbers isn't usually accurate unless you baselined before you changed anything and are using weather correction (SAE), most dyno operators don't turn on SAE and use the STD which isn't correcting for conditions. This is why are numbers or quoted in crank hp.

I believe I saw some other tuners can also make it so you can always see which gear your vehicle is in within the gauge cluster area. Do you have the ability to do things like that as well in tandem with your adapt-x tune?

I just recently got my Explorer ST and winter is coming up quickly so I will keep you in mind come spring when I am sure I will be excited to pick a tune. Thanks!

It really depends, you're talking about the firmware of the rom, the actual source code that makes up the software on the ecu. You are essentially taking a rom designed for a certain trim/package and then flashing that to a vehicle that to a vehicle that didn't have that same rom.

If one trim package offers it and the other doesn't, that's a "strategy code" change and an entirely different rom file. I typically like to keep the same rom the ecu came with and then apply our changes that make up the tune. This is why mustang owners lose their drive modes with some tuners because some tuners rather send out 1 file for all ecu's vs. having a patch file for each rom individually.

TLDR, if your current rom doesn't have it then you won't have it with Adapt-X, I like to be as least invasive as possible. The goal of Adapt-X is too keep as many tables factory as possible, less is more. I only touch what I need to touch to increase power.

Hi again!

I was curious if you heard about the Ford Performance Tune and what you think the benefits of your tune are over that one? You may need more time to see what the FP tune really has to offer in real-world data so no rush but would love to hear your thoughts.

There isn't really any comparison to be honest. The FRPP tune advertises a 30 HP gain at the crank, while the Adapt-X on 93 octane is around 110 HP at the crank. This equates to roughly 5-7 mph trap speed gain in the 1/4 mile over stock depending on conditions.

This code only applies to tunes, not device bundles.
