Heat soak affects many other factors besides air temp such as hot injectors, hot fuel rail etc. Usually to take care of this you would set up the IAT trim table as a 3D table with either Engine running time on one axis. You can then add a little extra fuel at high IAT for the first 40seconds or so of running. You also want a IAT sensor that has a reasonable response time and is exposed to the air stream well. Why would you recommend engine running time instead of MGP, MAP or TP? Is it better if we take into consideration when the car moves?
