relax, all ms boxs can do ign and fuel with the right config and hardware mods. just so long as you can trigger it well enough, it can do spark.
as for iat :
any will work... i'm using an open one from a "hi n dry" as open ones are faster than closed. corollas use a closed type. most every car has one.
go to a yard and find one thats physically suitable, and get it. get a pigtail and or plug whatever it needs too. get it to a fixed temperature that you know, and read its resistance, then change the temp to another and get it there. you'll end up with a curve like this :
(this is a coolant sensor curve, but still)
i did that with a fridge and hot water and a digi thermometer and a dvm, easy.
