whats the difference between iat and iat2 and how close should they be together? cruising around at 50mph with it being around 80 outside iat and iat2 both read 81. after a pull iat2 rose about 20 degrees higher than iat, 81 vs 102 at 6200. once i let off then iat rose up to 91 then slower tapered back down to 81 after some driving. iat2 took longer to get back to 81.
noticed this after a log and just wondering where each of the sensors are and how they should compare to each other.
the part in the log im talking about is the second pull i did.
