Digital cluster swap need help please

[Thats550]

I just finished swapping the analog cluster on my 2017 mustang gt premuim. My old cluster broke and Im not able to save any data out of it. But i did make a save file of my data when i first got forscan. I do know the mileage it's at cause I haven't driven the car in months. But my main issue is that the RPMs are not showing on the new cluster. It just shows zero rpms? Any thoughts or suggestions? Also will it be an issue if I'm not able to save my original clusters data

I'm pretty sure I have a saved file of my abd from before when I first got forscan. I should still have it saved on my computer, does anyone know where it saves to? If that will help me. I'm going over the post on how to modify asbuilt data right now!!
