Yes the Apexi pfc (which you have) has an option to add or remove fuel below or above a certain temperature which i can adjust when i map her Tuesday. Many dont alter these settings which is why so many cars have issues starting when turned off hot (say whilst refuelling) then if they dont start straight away they flood, same goes for overfuelling below a certain temperature!
Trouble is that if im honest it is a bit of guesswork as the car is hot when you map it so unless you have it for hours after to see how it starts & runs on a cold day you can only guess the fuel % to add or remove
But at least we know what your car does Rob so il pull some fuel out of the whole map with temps below say 30 degrees fahrenheit.
Smell the oil night before you leave and if it smells strongly of fuel just chuck some cheap oil in it and we will change it for the good stuff just before it goes on dyno.
