In addition to an ECU coolant temperature data read (thats a pain to get), useful to those with ECU plug ins, there is a second consumer driven coolant temp guage that sends a general current feed via wire to dash screen ( essentially an idiot style approach with no specific temp). I want the ECU data, which seems to have actual temp.
I propose adding ECU data via a hard wire or Wifi to an aftermarket screen, mounted near dash.
