SuperChips FlashCal F5 Plug n Play Speedometer Calibration Programmer ?

Did you ever get a response from Holley? Having same issue, installed update, but doesn't seem to save settings on 2023 2.3L (tire size, auto start/stop disable). Check engine message comes on until I reset to stock. Sent email as well. Have flashcal on F150 and previous super-duty's with no issues.
Yes I spoke with them and they told me they don’t have the Flashcal ready for the 2023 yet. Now this was several months ago and I thought I seen on here somewhere that they updated it. Let me know what you find out because I’m still just driving it without updating. I’ll say though that it drives just fine unlike my JK Wrangler that definitely needed a shift point change after 35’s.

So I got mine and tried it out. I tried the tire recalibration to (34) and at first it gave me the service 4x4 error (my heart sank into my stomach). I think that’s my bad as I thought I needed to unplug the unit from the OBD port so I did that as I thought I read to try and unplug it after each change but I realized I didn't go through the full cycle...
Then I moved on from that and tried other options, it seems I got the auto start/stop disabled and the double honk gone successfully as per the module. Will test those out tomorrow.
Then I tried again for the tires.
It automatically cleared the DTCs!
I did the process again and it said successful.
But when I go back to the tires option, it defaults to the size 32.
Does that mean it’s set at the stock 32 size or that’s just what the Flashcal will show and I’m actually good and all set at 34?

My Flashcal did the same thing on the tire size ie. reverted back to OE size. The only thing that I could make work with the Flashcal was disable double honk. Guess I will have to wait on an a software update from Holley.....So I got mine and tried it out.

I have the flashcal, it is not 2023 compliant yet. I don't know how you would of bought for 2023 as it plainly states 21-22. If you search under 2023, it is not available.

So the auto start-stop disable worked, the double honk removal worked, set TPMS for front & rear down a few PSI, and...I checked my speed via waze and the speedo is just 1mph off! So seems it worked as far as the tire calibration? Maybe it just always defaults to show you 32.00 as the starting point?

I’ve had the Flashcal for awhile now. I’m running 37 Yoko’s. I had the Flashcal set for 36.00 for the tire size, speedo was reading 3 mph fast. Getting ready for the drive out to Moab, thought I’d get it dialed in. After trying a few different sizes, 34.75 turns out to be the magical setting on mine. Finally my speedo matches gps. Just thought I’d throw this out there if anybody else is having issues getting an accurate reading.
