Note: "cold" is 20 degrees C.

I had a mate help me adjust mine last year. About a 40 minute drive to his place so we set it for the hot adjustment. It made a noticeable difference with power and economy.

thanks for that taslucas, the car isnt really in one piece so a warm start isn't all hat practical at the moment
