Return ECU to stock via FlashPro

[Major Ram]

I'm running into a bit of an issue with my 2017+ Type R Americas (OG) FlashPro on my 2024 FL5 Civic Type R, and I'm hoping someone with more Hondata experience can help me understand what's happening.

Current setup:

• 2017+ Type R Americas FlashPro
• TSP Stage 1 tune
• FlashPro has two calibrations loaded (I verified double checked it):
  • Slot 1: TSP Stage 1 tune
  • Slot 2: 2023+ FL5 Factory Settings calibration

Since I didn't have access to a Windows laptop at the time, I decided to switch back to the factory calibration using only the FlashPro.

I followed the button sequence exactly as described:

1. Press and keep holding the Datalog button.
2. While holding it, press and hold the Program button for about 2 seconds.
3. Release the Program button.
4. Release the Datalog button.

The Program LED began flashing, the dashboard went through the normal programming sequence, and after a few minutes the upload appeared to complete successfully.

However, when I took the car for a drive, I noticed that I could still switch between the five maps of TSP1 using the cruise control buttons. That confused me because I expected the FlashPro to have loaded the factory calibration from Slot 2, which I assumed wouldn't have the TSP map switching functionality.

When I got back home, I connected the FlashPro to both my laptop and the car. The software displayed a message stating something along the lines of "The last upload was successful."

At this point, I'm trying to understand what actually happened and whether I'm misunderstanding how the FlashPro handles multiple calibrations.

I have a few questions:

1. Why am I still able to switch between the five maps after I thought I had flashed the factory calibration from Slot 2? Where can I see what is the current calibration on my ECU?

2. I'm unable to download the calibration that's currently on the ECU because the Online → Download option is grayed out, even though the FlashPro is connected to both the laptop and the vehicle. Is there a reason this option would be disabled?

3. What is the exact difference between:

• Online → Return ECU to Stock, and
• flashing the 2023+ FL5 Factory Settings calibration that's stored in Slot 2 of the FlashPro?

Are these functionally identical, or do they perform different operations?

4. When I try to upload a different calibration from my laptop to the FlashPro (with the FlashPro connected only to the laptop and not the car), I receive the following error:

"This FlashPro can only be used with Civic Type R 2017+ Americas vehicles. The current vehicle is unknown."

Is this expected behavior when the FlashPro isn't connected to the vehicle, or could it indicate a configuration or licensing issue?

At this point, I'm not sure whether the FlashPro is behaving normally, or whether something isn't configured correctly.

I'd really appreciate any insight from those who have experience with these kind of issues.

I don’t think you can upload the “return to stock” map to the Flashpro, and then upload it to your ECU (though I don’t know that for sure). I believe you need a laptop and internet connection to truly return to stock. At least this is how I understand it, and I have done it this way.
The difference between Hondata’s factory stock calibration and “return to stock” is that the former is a calibration that is tunable, but nothing has been changed from the factory settings, and the latter is factory software straight from Honda, which can’t be altered.

If you’re taking your car in for warranty work, or looking to pass state emissions testing, you want “return to stock” because that is genuine software with the proper calibration ID and verification number that certain party poopers might be looking to bust you on.

I’m sorry I can’t help with your other questions, as I’ve never tried uploading a calibration without using a laptop. Is your flashpro manager software and firmware up to date?

What is the purpose of your going back to the stock calibration?

Yes, eventually I did use the 'Return ECU the stock' without a wifi/internet connection but along with the flashPro and the laptop. The flashpro manager was up to date.
The reason I wanted to return to stock settings is that the car is going to checked for emissions and testing to be able to pass the UK road tests. Hence, I didnt want to take any chances by sending the car on TSP1 tune and the shipping staff accidently put 87 Oct fuel in it.

I read somewhere( can't remember now) a trustworthy source, that you can switch between the calibrations stored in primary and secondary slot of the flashpro without needing a laptop or internet connection.
So, at first I tried uploading the 'Civic type R fl5 2023+ factory settings' which was in my slot 2. But when I took it for a drive, I was still able to browse through the 5 maps using the cruise control button.
