mr computer
already has control of fuel and timing so
mr computer
will match air temp to a calculated value of timing and fuel volume which will be corrected in a feedback loop
from inputs from the AFR or 02 sensor in the exhaust

you
can not change anything

mr computer has control
so
heat the air as much as you feel will help ,
watch knock retard values in your scan tool and when they start to increase
beyond the baseline value
stop increasing air temp

of course you need a baseline scan data test graphed or logged of knock retard
at various loads
and ambient temperatures
before you begin your modification
