Hello, I have a problem with starting motor in the morning (log attached) I can smell unburned fuel before it starts after a few tries, currently the temperature is -1.5 to 2 degrees. I changed the HPFP and spark plugs, it didn't help. When it was warmer 15 degrees it was ok ( i mean september 2024 ). Please advise if it's a problem with the MGFlasher version or something else, the car has a mileage of 70,000 KM
