How do I reprogram a computer to

you don't.

 

Why ?
That's is pretty much what the B gearshift position is for.

 

The biggest issue is just reprogramming windows, it's not an open source code software like linux.

 

Wait.......what......are you saying that Toyota cars use Windows as their underlying operating system ???
I certainly hope not.

 

Are they talking about engine Brake mode? You can do it manually but it ruins your fuel economy if you do that.

 

What i just you may have noticed, is that if you badly state your desire, no one can solve your request.

If you lightly apply the gas pedal, you can indeed get all the arrows to go away.

Since no other car on the road behaves like what you request, Toyota's liability would be phenomenal. (as I understand your request)

 

Or just throw it in neutral.

 

Well he said "reprogram a computer", I figured he meant using a PC that's equipped with windows that's written with visual basic computer programming language, connected to the vehicle to perform the specific operation. And not the prius internal software.

 

Wow! Those are some assumptions!

I program quite a bit, never use Visual Basic and rarely program for or on Windows.

 

Easy solution: You get a car that allows more regen (drag/braking) when lifting off the pedal. One pedal driving is really, really nice.

The only "hacking" I've seen here is using Techstream and that's only changing factory settings but I guess that would be the place to start. Or maybe one of the phone/tablet apps.....

 

From 1985 to 1988 I wrote for IBM PCs, in various languages, including IBM BASIC which was just re-branded QuickBASIC. Before, during. and after that, I wrote in RPG for the IBM S/36 (and once in COBOL). In 1992 I switched to SQL and PL/SQL on Oracle until 2002. (once a tiny bit of C, and once a trivial amount of ForTran, both on Unix)

There is much to do that is not Visual Basic. The trick is using the right language for the right task. (bit manipulation in COBOL was not easy. Four lines of IBM BASIC became 260 lines of IBM COBOL)

 

Lately I seem to use php a lot either for web page applications or Linux shell scripts manipulating text data and using REST APIs.

 

you can't.

 

Once again.....WHY do you want to do that ??

Answer (again): You can't because it is re-charging the battery a little bit when it's doing that.

If you insist on free-wheeling mode, you have to shift to Neutral.....or as mentioned, feather the gas pedal and watch the display, but there is NO good reason to do that.

 

And again, if you DO succeed, every other driver who ever borrows your car will be at risk, as no other car does this.

My younger brother once switched his front brake and clutch levers on his motocross bike, no one who ever rode a motorcycle before could adapt, they all crashed. Changing something so fundamental on your car will be similar, expect folks to rear end the car in front of them.

 

It also may well be illegal to drive such a modified vehicle on public roads.

 

Recomendation:

Don't try to out think the engineers, designers and programmers of the Toyota HSD system.
Just drive it.
