If your ltft is always 0 then i think your tuner has made car run in closed loop all the time and disabled ltft, you usually see ltft vary a couple of percent with temperature.
High under hood temp on NA cars are only realy an issue at very low speeds and stoped once your moving iat comes down quickly.
If much easier to make radiator fans run at low speeds ,table change in tune, to cool engine bay than messing with insulating intake and venting. although an easy vent is unclipping the plastic piece on the underside of the hood on the RHS of car above the overpipe.
oil coolers even the oem type are a good investment in hot climates if you drive hard as is a 5w30 or 10w30 oil depending on climate.
IAT temps higher than about 90F will start to pull timing ,but depends on tune
you need to look at FLKC fine learning knock control as well as iam to see if timing being pulled due knock.
for other compensations like iat and oil temp coolant temp you would need to look at tune tables .
