I’m wondering if anyone has bought an OBD2 sensor for their 2023/2024 Prius Prime? I am looking to buy one to see some more information such as fuel mileage and other EV specs. I am kinda hoping that I can see the true fuel mileage and not the mileage combined with EV use (I think it’s dumb Toyota did that as mine shows my average to be 2.2 L/100 when in reality it’s more like 4.5). Thanks!
OBDEleven seems OK. Suits the VW group best, but there's some interesting Prius tweaks in there. You do need their dongle of course and credits to purchase modifications. OBDeleven: Car diagnostic tool & OBD2 scanner
The way you explained your question leads to more questions. At least you put in what you think is Dumb and what you'd prefer instead of it. You obviously did some mafhs in you head or on paper to come up with your approximate real number instead of what you see on the dash gauge. When you do find an app the calculates out the electrified asst. portion of the mpg reading on the dash gauge, please let us all know how well it does that calculation.
