What are most people seeing as a difference between intake temp and ambient? My intake temp using Cobb intercooler is always 10-12F higher than ambient

That’s normal, intake temp is right after the air filter, the heat from the engine and error in the sensor will cause that.

watch it in traffic or take the lid off the air box should go above 100

Mine usually stays right around ambient when driving. Also I don't really see any difference with or without the lid on the air box.

If you mean the car is parked in a garage overnight and when you key-on (but not start the engine) there's a difference, well the 15+ cars had something screwy in terms of voltage to temp calculation in Cobbs software. Some tuners account for this and some don't.

Charge air temp is after the intercooler. IAT is after the filter. Ambient air temp is bottom of the passenger mirror.

2015 intercooler charge temp thread

Im trying to put together a discussion for the 2015 cars, and some 13/14 cars for arguments sake, running aftermarket intercoolers. From what i've been reading on here it seems that with the right combination the 13/14 cars can keep their charge temps around 10* above ambient, however with an...

If I go out in the morning and put my car in accessory mode. My charge air temp will read 18° higher than Ambient. Therefore it's 18° off.

That makes me think we need a tilt meter, then we could see who could get the highest angle without flipping it?! 🤔😳🤣
