I was reading up on the features of the Megasquirt II and I came across some sort of CLT/IAT sensor. I'm pretty sure the CLT means 'Closed Loop Throttle', but I don't know what 'IAT' stands for. What is happening when the car's in closed loop throttle also?

They are both explained in the MS documentation and are not new terms in the automotive industry. CLT = Coolant Temp sensor. IAT = intake air temp.

Don't feel bad Mr new guy. I, at one time, had pretty much the same question, with pretty much the same response, from pretty much the same individuals
