Carista. It’s an OBD2 plugin, $40 with a free month of access, which is all you need to customize all that kind of stuff.https://caristaapp.com/. Source: about 1 year ago

Yes, using an OBD2 tool like Carista (or others). This is by far the best mod I’ve made to my truck. Source: about 1 year ago

Carista is one of the companies that sells 3rd party programming modules. Source: about 1 year ago

I don't remember if either of those are an option -- I believe mine is supposed to beep, but I've noticed one of mine has quit beeping when I leave the keys inside, so maybe I should check, but a paid subscription or the free trial of expanded options from the Carista reader/app does give you more control of the beeps and door locks than a regular OBD2 reader.

I personally like my Carista because it's optimized for Toyotas and Prii, so it reads a bunch of ECUs the other readers don't see, but there are less expensive models available via Prime. The Dr Prius website has a page comparing several models, which they supplement by linking to the Hybrid Assistant site. Source: over 1 year ago

I'd also recommend experimentation with new methods per each tank of gas and use fuelly.com to track and add notes to see which methods work the best for your specific Prius and use case over time. Source: about 1 year ago

Sure there is. Go check out fuelly.com and tell me that you wouldn't be able to estimate pretty closely the mpg of any car you own based on that data and considering your own driving style. Source: about 1 year ago

As to the data the article is using... It mentioned fuelly.com as a source. Just clicking on a few PHEVs from that website, it's abundantly clear how tiny the data set is. Nor does it seem to do much in the way of data verification. I just pulled up the listing for the Chevy Volt. Somehow I doubt there are dozens of people between 200 mpge and 500 mpge (200 mpge = 6 mi/kWh), and even 2 cars are listed at 1 mpge! Source: about 1 year ago

Nice! I have a 2015 corolla LE and my best tank was 50.8 MPG on 412 miles. It was a trip from KY to OH cruising around 65 mph mostly. I average 42.8 MPG across 140,264 miles tracked via fuelly.com. If I didnt live in cold Michigan winters it would be higher. Very fuel-efficent gas-only car, definitely capable of 50+ MPG with the right conditions and certain manner of driving.
