IAT is 39?
Ok, why is my scanning tool reading 39 degrees F when it is 83 F while I'm driving? Have I clicked the wrong PID or something? Having an IAT that low is probably great for not pulling timing but it's a lie and I'm sure the ECM knows that the IAT is at LEAST 83 because it is 83 here!

I'm missing a post in here that suggested a broken wire.
When I have this tune in the car, my IAT is an average 166F I am still using the same wires, IAT sensor but now I read a correct temperature. I am using the same PIDs. I must conclude that there is something wrong with the first tune I attached.

Elmer, I saw that your log file shows what appears to be a valid IAT so it can't be a broken wire (IIRC broken wire gives something like -39°F).

I only have 1 IAT PID to select? SAE.IAT
It reads perfectly on the 2nd tune in post #2 but goes to shit on the first tune post #1.
After further review, I see a 2nd IAT PID called IAT2. GM.IAT2
IS that what I really need? The IAT PID works just fine on the 2nd tune I attached.
Elmer, that is strange, I don't see how that could happen.
Uh-oh. I think I'm in deep shit if you're stumped!Originally Posted by joecar
Can you make this happen simply by flashing in the file from post #1...?
Yep, absolutely every friggen time! That's what started this post! It's playing screw-screw with my mind!
The second tune is an E-Force tune from Edelbrock that is scaled down by 25% It throws off my DIC instant gas mileage reading by 25% and the "Remaining Miles" is a total joke. The first tune is by my local tuner that is NOT scaled and gives my DIC readings correctly. I would prefer to use the 1st tune but something is wrong in the tune.
