Welcome - and Merry Christmas 
As Leo said, more information please!
Assuming you’re calibrating with an ARC app (with Pro, Air or One? Scalextric app or Magic?), it can be a hardware or software issue... are these cars a problem running without the app?
The motor in the F1 cars is a little feisty - mine calibrate okay. However, with traction magnets removed - or running analogue with a digital chip fitted - may be an issue with the latest Scalextric app.
An option would be to try the original App Race Control (Legacy) app, which is still available from the AppStore and GooglePlay. You lose a little, but gain a much more gradual calibration slider.
I hope that helps.
