I have aldldroid installed on my Samsung 4. I use it to read the ECM and I'm getting something interesting/odd with the coolant temperature reading. Everything else works well but the temperature starts out high 175 when cold and drops to about 59 when warm. Anyone else have this problem ? I'm using the A001 file to read the ecm.

Sorry, I have Torque. But just to be clear, your gauge is showing what you think is the correct temp? But the app is misinterpreting the data?
Did your device do a recent update?

To update, I've checked it with tunerpro now and the ecm shows the correct temperature which is close to the guage. The app in ALDLdroid must be interpreting the data wrong. I also seem to be getting and IAC error. It does show the IAC numbers moving however.
