Prius CAN Monitor and data logger for Windows PC

[ken1784]

Hello all,

I'm pleased to announce that 83GTP@Tokyo developed the Prius CAN Monitor (or PCM) and data logger for Windows PC.

The PCM uses CAN232 to receive the CAN messages from Prius and displays them on the PC screen, also stores the data every 0.1 second on the PC's disk as a CSV file.
You can analyze the data later using any spreadsheet software such as OpenOffice or maybe MS Excel.

Right now, it uses Japanese Windows fonts, therefore it works only on the Japanese Windows 2000 or XP.
However, he is now working hard to migrate it to the English version of Windows.

Regarding to the fuel usage, the CAN messages don't have accurate data, so it receives the alternate data from my SuperMID M-1 mileage meter through another RS23C serial port. These data is displayed last two lines of the screen shown below.

If you would like to see some sample CSV output, please download followings...

Enjoy,
Ken@Japan

PS. Many thanks to Attila for decoding the CAN messages.

I like it! Its just what I was thinking someone should do. Now if it could be open source, and have a nicer display like the Japanese version of the canview or have a fully customized display with graphs then it would be complete. I will still take it like it is. Now I cant wait to get my in car computer.

[Cheap!]

Put me down for one too. Man I guess I am going to have to find another place to keep my wallet and phone as I will need the middle cubby for a pop out touch screen computer now!

Pretty sweet ken...

If anyone wants to collaborate on an open source, linux-based version of this (sorry ken, but i really hate windows), i have plans to start work on it in the next month or so. The final goal, of course, is to use it in a car-puter, but thats a ways off.

Very nice!
I will get this installed into the carputer soon to give it a shot

He agrees that the VB source will be open after he finished the migration to the English Windows.
However, he does not have a PC running the English Windows now.
Are there any volunteers who has the CAN232 to do the beta test?

Please be aware that it'll be a beer-ware and you have to treat him to a couple of beers when you guys met him in the States.

I can understand what you're saying as I wrote OpenOffice first.
Hope someone can migrate it from VB to C for X Window or even Java.

Yes, it works on 2004-2007 Prius. The required signal is just CAN on the the DLC-3(OBD-II) connector.

It is reading the CAN information out of the OBDII connector.

I think its a sofware interpreter/app displaying graphics on a PC hardware on any type, carputer, notebook. I'm using a program that diplays partial information of the Prius because is not supporting 100% Hybrid information with the same CAN232 hardware through an USB adaptor since the last 6 months.
In this picture you can see it in the 10" LCD display

Really this NEW app shows very nice.

Hi Ken,

Could you give more details about the inaccuracies between the CAN message injector timing and the direct measurements?

With Graham's miniscanner, I see the OBD injector timing values even when the ICE is off. Are there other problems with values being just wrong?

Thanks,

Will it work on Lunix or OS X
