easytherm freezes on me everytime.
ms2 dler wasnt working properly for me.
scott showed me how to change the file in teh DIR.

none of those solved my problem for my IAT.

it still reads 60*

Verify the sensor is functional with a DMM and water maybe to rule that out so you know for sure.
Otherwise maybe a component in the temp sender circuit on the board is fried. I haven't looked at the schematics in months so I don't even know where to start right now.

i already used a multimeter on the sensor and im getting resistance. diff readings at diff temps.

ok so i fixed my IAT problem.
one of the resistors wasn't soldered to the board... (r4)

now i just need to fix my vaccum leak.

are you for serious? I wonder how the heck that happened. Or maybe I did it to fuck with your mind...
