[QUOTE="jn2, post: 15392713, member: 178010"] Correct. The ECM still think's the IAT signal it's getting is at the MAF, but it's actually from the IAT sensor. This gives you a accurate reading so you don't have to guesstimate your IAT2's, but since your tune prob has spark corrections based on IAT1's it doesn't play well with the new sensor.
