Hypertech vs ford performance tuner vs other??

[SD4160]

Hey everyone. So now that my new wheels and tires are on, I'm looking for the best approach to calibrating my speedometer. Ultimately, I would like to add a tune to my truck, but for the moment, not looking to void my warranty, I'm happy with "S mode" and just want the speedo calibration.

If not for the current fuel costs for premium, I'd add the ford performance tune as soon as it's available for the 2022's, but I'm not looking to commit to 91+ all the time in my Ranger just yet. I also don't think it will calibrate to my current tire size (275/70R17) if I've read their product info correctly.

So I guess my question is, what would be the best route to go for now?

I'm thinking hypertech at the moment as the ford performance tune is still in the works. Am I missing any obvious route here? Thanks!

Read up on this forum about Forscan. You get a USB to OBDII cable and you can make all kinds of changes, including tire size. No change to engine performance.

Will do! Ive definitely crossed paths with forscan content on here, and have a light grasp on what it is/does. But I will certainly dig deeper.

Is it similar to an aftermarket tune or hypertech speedometer calibration in that factory settings can be saved and restored to OEM settings to ummm... hide what you've been up to and risk voiding warranty?

Also, would it interfere with any tune that I choose to add down the line?

I recall reading I can use it to turn off the "engine running, Key fob not detected" double honk that still scares the shit out of me every time it goes off after I close a door. That would be lovely.

I'm poor and have a key that goes in the ignition... so I can't speak to that.

You do save your OE settings to flash back, BUT... Any time you flash, the counter is increased (the thing Mother Ford looks at to tell if its been flashed) each time. You can't fool Mother Ford, if they want to dig.

As mentioned, Ford will know.

Even if you just used it to change tire size, I believe the flash counter would increment.

I believe it also counts ignition cycles since the last flash so if you flash it back to stock before taking it to the dealer, the dealer will see that the truck has been started 4 times since you bought it.

You've both confirmed what I originally believed to be true, then let a friend convince me was not. I said "it's 2022, how can it not know and track what I've done to it?" And he was like, "they don't give a shit"... maybe his nonchalant answer should have clued me into diving deeper for an actual answer?

Thank you both. May dive into forscan even just to have for diagnostic purposes. Which will inevitably lead to me tinkering.

If I waited until the ford performance tune was out for '22s, would the flash counter differentiate between a tire size adjustment and flashing a different tune variation supplied by Ford performance?

Sorry for all the questions and hypotheticals... this is new territory for me.

No worries. We all had to learn sometime. I have a buddy who is a GSM at a local dealer. He said the techs wouldn’t check, as they want the warranty work. The only reason they’d check is if mother ford made them. That being said, they’d have to prove your flash caused the problem. That’s great in theory, but harder when they deny your claim. You’d have to get a lawyer involved, me thinks.

Doesn't forscan write to the BCM while the ford performance tuner writes to the PCM?

Yes. But it still ticks the counter.

Is a tune the only way to recalibrate speedometer/ odometer? Looking at possibly 265/70s but the stock 255/65 dueler rhs has not been bad for me honestly

I mean, something has to tell the computer the size is different. Or just deal with the speedo/mileage being slightly off.

Yeah but the dealer isn’t able to update it through their computer systems without installing a tune?

I think you are all reading way too much into Forscan. Forscan does not flash any software changes like a tune does. Tunes do flash software changes to the PCM and are tracked. What it does do is allow you to download and adjust settings in various modules to change options in those modules. Forscan has been around for a long tie and used by many people on all different models of Ford vehicles

Our trucks have a couple dozen+ modules (mini computers) that control various features. Each module has a setup (configuration file) called an As-Built file. What Forscan allows you to do is view and edit these files, changing the built-in options to your liking. In fact the current versions give you an easy menu to select these options. Like disabling some of the various beeps that can be annoying, changing tire size to correct speedo and milage calculation, how the driving lights work. Even change the boot up flash screen on the SYNC screen. Nothing you can do will hurt your truck or cannot be reversed by simply reloading your backup file.

I and many others on this forum have made many changes to our trucks with Forscan. If you look at the Forscan threads here you will see lists of the available changes you can make. I have never heard of anyone getting in trouble with a dealer for making these changes.

I agree with everything you said, but he asked about the flash counter and Forscan still affects the flash counter. At least from everything I have read, it affects the flash counter. Unless you know differently from experience, I will still caution users concerned about the flash counter.

They should be able to.

If I can do it in ForScan I don't know why Ford techs wouldn't be able to.
