Another strange thing. Must be a quality issue, none of my 2019's (both 300's) pinged on deceleration...

Hi, I suffered from decel ping/ knock on my 2018 300 that I couldn't seem to jet out. Checked the comp ratio and it was 13.85:1 std. With high sqish. Fitted the S3 head with highest comp black insert which reduces comp to 13:1 with reduced squish which cured my running problems. I have been told that the std 19 head is lower comp STD. I'm in the UK and suspect that different fuels across the world will have different effects .

Fuels are high quality over here, I can run 95 which we call "super", 98 "super plus" and 101 "power". The latter one is incredibly expensive so I don't use it. Has anyone with a EC300 tried the cylinder head of the GP model? Allegedly it should be "better" whatever that means.... |
