Gen IV Prius Prime Custom PIDs for Torque app

Is it possible to get the transmission temperature and TPMS psi data?

 

According to this post, we can convert ScanGauge code to work in Torque..

Guide: Converting ScanGauge Codes to Torque Pro PIDs - Toyota Tundra Forums : Tundra Solutions Forum

ScanGauge transmission temp for Prius Prime is :

• Gauge: Trans Oil Temp
  
• TXD: 07D2221004
  
• RXF: C46200000000
  
• RXD: 4008
  
• MTH: 00090005FFD8
  
• Name: TOT

So I converted it to Torque PID format:

PID: 221004
Equation: E*(9/5)-40

...but it didn't work...anyone knows what I did wrong???

 

If you want your diagnostics to be as thorough as possible then you should be using Torque Pro. Using the regular version of torque will give you PIDs like any other but Pro version has extra sensors that you might need in your case. And you can get it set up in Windows too if you want. That’s what I did.

 

I do have torque pro

Can you share the setting to display transmission fluid temperature and possibly individual tire pressure???

 

I recently got an OBD2 adapter because I've got a soft spot for viewing data on my 2018 Prime, but neither Hybrid Assistant or Torque Pro appear to track what I really want to know: what's my kWh/mile? My commute is 100% electric, so tracking my mpg is pretty useless as a measure of how efficient I am driving.

Has anyone figured out how to do this yet? If not, can anyone direct me to some resources explaining more about PIDs (i.e. something more high level then "this is how you make a custom PID" so I can better understand what/why/how cars are measuring and reporting these values)? I don't mind putting some work into getting something working if no one has already done this, but I know exactly nothing in this area. Any help is appreciated.

 

That data is already available. In fact, yesterday I was messing with it to see how much of an impact the heat-pump would have a maximum with the temperature outside at 16°F. See:

 

Oh woops! Can't believe I overlooked that. Seems like I don't my Prius Prime's features as well as I should yet.

 

Anyone know the PID to enable auto window roll down with fob?

 

It's rather surprising to me that even though there are apparently lots more Primes than PiP, we have the PIDs for the PiP but not the Prime. It would be fun to learn how to make them if I had the time.

 

I ended up getting a cable and techstream off Ebay. Was able to change a lot of options on the car

 

I have that. But sometimes we just want to monitor temperatures or battery conditions while driving and a laptop with tiny numbers while driving is just way too cumbersome and unsafe compared to big dials on a phone in its dash mount.

 

Reverse-engineering that kind of proprietary stuff is just super squinty, tedious, frustrating work. A lot of the Gen 1 PIDs were figured out by vincent1449p and I don't even want to guess how long it took. A new model more or less has to wait for somebody who has access to one, and the motivation, and the skills, and maybe is between gigs of using the skills for other better-paying purposes....

 

Yeah, I figured as much. That's why I never seem to get around to it. Too many other more important things to do.

 

This is what I got for my Prius v/alpha/Plus.
