Does my 2022 Hyundai Elantra N’s power output actually fluctuate depending on when I get gas?
Is octane learning real and does it impact performance?

All data was collected via a Dragy GPS and an OBDII scanner.

For those who aren’t familiar, Dragy uses high speed GPS satellites to accurately measure your vehicle's speed and location within 1/100th of a second. It’s more accurate than the car itself and eliminates the car’s gauge cluster as a variable. The OBDII data comes directly from the CAN bus via querying selected PID’s in real time as the car is driving.
