Nozzle spray angle...

[rotrex]

You might just pull timing some 20C past the IATs you usually get with a nozzle spraying before the sensor.
There is a IAT ignition correction table in your ECU that can be used as a kind of fail safety.
The same would work for the fuel IAT correction.
This would work on top of closed loop fueling maintaining your AFR if WI fails or injects less than intended.
