Cold Weather Detonation
Tonight was the first "cold" night here in Northern Florida (upper 40's, you northerners don't laugh!), and my car is now detonating pretty hard. Car was recently dyno tuned with new 42 pound injectors and 90 mm MAS. Car ran great in the sweltering heat, but tonight's pinging really surprised me. If I got into it anywhere above 4000 rpms, right when the boost fun starts, I'd have to get right off it because of detonation. Any suggestions or similar experiences out there? I really can't have a car that runs great in the heat and sucks in the cool weather.
