Hello please think about get better from other app user input value ADC and then input value as he want see ![photo_2023-04-25_15-40-47.jpg](https://forum.realdash.net/uploads/default/original/1X/79e4b2ba5d7757a2c989f54115dd92cb6c0142de.jpeg) ![photo_2023-04-25_15-18-36.jpg](https://forum.realdash.net/uploads/default/original/1X/1a0adeacdcf2e65a27c88bc529679009ccda42f9.jpeg) ---

Already have similar system: - Select the ECU Specific input on the list and then burger menu ‘Edit’ - Check the ‘Use Custom Mapping’ option to enable advanced UI for value scaling. ---

Please think about upgrade ( now i use long triggers ) we can conduct a quadratic function through three points a\*x^2+b^x+c=y ![abc](https://forum.realdash.net/uploads/default/original/1X/ca17697362172a8dde6d7d92e4bbf29c8a031d1b.jpeg) ![image](https://forum.realdash.net/uploads/default/original/1X/a0b7f999e1aee319c53b9681b3d81a2f40a511e5.png) ---

To my opinion, setting points with linear interpolation should be precise enough for any automotive sensor. Any more complex math should be handled in ECU/device side. ---

Custom mapping is not saved in RD file. Nothing custom input related is, as custom inputs are only connection related. Its saved locally to user data. ---

But its true, the custom mapping does not propagate to different devices but is only saved locally. ---
