I’d just use ScanGuage. Unless you are running a second gauge.
Yup. No worries of OBD with the dieselsHDJ's were all (to my knowledge) OBD-Nothing...no OBD 1/2 port to connect something like a scangauge to like the gas engine trucks to monitor trans temp.
I see you were responding to someone with a gasser, but thought I'd throw my $.02 in.
