Has anyone experienced a sensor reading that is higher or lower than others after a Cold Soak? After getting my BT adapter and the app. configured the way this thread and the thread on the Torque forums said to, my ECT reads 15-17 degrees colder than my IAT sensor and EOT sensor. I have verified this with a Infrared temp gun pointed at the thermo housing on the engine, and verified the IAT temp (within a degree or 2) using multiple outside temperature sources. This temperature differential exists even when fully warmed and does not get larger.
So which is it? the gauge reading, or the sensor itself? Should I just offset the reading by 16 degrees so that it reads where i think it should read?
Would a faulty adapter cause readings to stop? I've triple checked the equations, everything is entered correctly, when the app first starts up everything reads like it should. No BT adapter errors, etc. Then my readings start to drop and drop then stay at 0. Right after that is when I get the faulty adapter error. It is an elm327.
This is what 'seems' to be working in my truck, It's a 20020 7.3 manual so YMMV. Cold soak temps are close and they increase with use, but I haven't verified the readings with infrared or anything.

thanks in advance
I'd offset it as well, but I dont think it's the gauge or the torque app...the equation is spot on.
Yes, at first I tried adjusting the gauge limits...but when it gets over certain points it goes to neg. pressure...I have yet to figure out how to fix that issue. I will play around with it to see if I can fix it.

Awesome! I tried the same things as you. Not even sure what to look at next.
Does anyone leave the App. running all the time? I tried and mine wouldnt reconnect I have to shut the App. down and turn it back on. I just dont like having to start everything every time I go somewhere. If you do where is the setting at to make it reconnect?
