So every once in a while I plug in my OBDII and open my car scanner for iphone to keep an eye on some values.
I am always left puzzled by WHY the IAT's on this car, idk if just MY car, is so high compared to ambient temps.
In my mustang 2.3t, I know I shouldnt compare but...Whenever cruising, regardless of outside temps, the IAT's would MATCH. So, if ambient temps were 70F, my IAT's would be sitting in the range of 70-73F and inevitably would go up slightly with idling, the longer the idle the higher itd go.
Yesterday, ambient temps were 55F at night, yet my IAT;s were 83-90F. No idling.
Is anybody who is tracking their values with an app along with OBD, seeing this as well? does this car BADLY need a better more efficient intercooler? or, as a possibility being that the APP itself is giving incorrect info?
As for boost, the highest ive seen so far is 1.2 bar which is about 17.4 psi.
