SOI Advice

It's my opinion the biggest condition affecting timing would be heat . The hotter the air gets the more advanced the timing will get to a point. Slightly higher boost levels due to cold air will affect it but not as much as the heat will . The hotter the air in the cylinder becomes the more volatile the environment becomes to ignite the fuel. To me in a hot climate with high torque loads you want to reduce Soi .
