Hi there,
My car is the Chinese version FL5，The modification of the car is exhaust and PRL intake.
use calibration is "civicR-2023-US-2-91octane-dp-int"
After a cold start, the engine will shake and there will be a significant increase in RPM.
This is my cold start log and calibration, please help me find out what is causing the engine to shake and rev up.
