    injector selection

    I live where the air temps run around 95 deg this time of year. How does the air temp affect fuel rate,does less dense air mean less fuel is needed for the correct afr ratio? Doesn't the density of fuel also drop with higher temps so what is the major factor air temp or fuel temp/density? How would this affect injector selection?

    you have to have big enough injector for proper fueling in the cool weather
    and the ecu will use the IAT to adjust the fuel ratio for the hot weather
