mattj Posted August 28, 2021 Report Share Posted August 28, 2021 I can't figure this one out... I'm using the AN Temp 3 and 4 with sensors for both coolant and oil. When I use the Deg F for output units in either Cal Table 1-3 or Cal Tables 7-10, I get temps that appear to be in Deg C. When I switch the Cal Table Output Units to Deg C, I get temps that appear to be in Deg F! What is happening here? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 28, 2021 Report Share Posted August 28, 2021 Can you give us a photo showing what you have. Quote Link to comment Share on other sites More sharing options...

I can't get a video under the 5MB limit. How in the heck did you do that? https://drive.google.com/file/d/1l88Q93Dc6240WLKgHAUUFCVaeOxzzxij/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 29, 2021 Report Share Posted August 29, 2021 If AN T3 is assigned to the function ECT, then you should be looking at the parameter "ECT", not "AN T3 - ECT". "AN T3- ECT" is what is used in the background and stored in the ECU etc and will always be in native units. ECT is the value that is converted to the correct display units. ECT paratmeter is displaying correctly isnt it? If you are using one of the GP temp functions then I suspect you will have to do the cal table in Deg C.

mattj Posted August 30, 2021 Author Report Share Posted August 30, 2021 Gotcha. Turns out I have both coolant temp sensors assigned to "Engine Coolant Temp". What happens when I do that? If I set the second coolant temp sensor to GP Temp, I don't have an option to select the GP Temp as a Function to monitor. Still says "AN T3 - {"my custom Label"}. It does this for my added sensors for other pressures too, except there is a built-in function for exhaust pressure (this one shows up correctly and displayed in PSI as expected), and a built-in function for "Crankcase Pressure - but this one doesn't display as crankcase pressure...just AN 4 - "my custom Label". I can show you in another video if that helps. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2021 Report Share Posted August 30, 2021 Yeah as I mentioned above, for any inputs that need to use a GP input, these dont have a separate "display parameter" so you will need to do your calibration table in native (metric) units in that case. Then the conversion should work correctly. Quote Link to comment Share on other sites More sharing options...

Both are listed in the pick list of choices for an analog input, but Exhaust Pressure is “defined” and “Crankcase Pressure” is not. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted August 31, 2021 Report Share Posted August 31, 2021 Exhaust pressure is used to correct the wideband reading when using Link CAN Lambdas Crank case pressure won't be used by any other feature and will simply be for display purposes Quote Link to comment Share on other sites More sharing options...
