I've searched but cannot find itmight try emailing forscan, see if they will tell me Edited 05/08/14 05:52 AM by burkey05 1 Link to comment Share on other sites More sharing options...

I am not sure how accurate this is.Results:Torque -------------- Forscan70 degrees -------------- 93.0 degrees78 degrees -------------- 95.6 degrees77 degrees -------------- 94.0 degrees75 degrees -------------- 93.1 degrees74 degrees -------------- 91.9 degreesPlease remember that you can not have both Torque and forscan running at the same time.Cruising home today and my app matches your figures pretty well (torque)I did notice that they are very similar temps to the trans fluid temp (have external cooler) Link to comment Share on other sites More sharing options...

I got the *5 /72 off a Siemens data sheet, they manufacture the CPU in the pcm(I think it was Siemens anyway...) it also had an offset of -512 but I couldn't even get close with it in the equation. Even with the data sheet it's hard to determine how to structure the equation, which could even vary depending on how the software calculated it(forscan, torque, proprietary scan tools)As for those temp readings they cant be right, engine oil needs to get to atleast 104 degrees Celsius to burn off contaminates from the oil(PCV system)As I have mentioned before if you still have the heat exchanger setup on your transmission, fluid temps should end up pretty close to ECT, science says so.

That can only be altered with the X4 right? Link to comment Share on other sites More sharing options...
