ppc/wm mpg software?

[Nerys]

Any suggestions? I used to have this great program for my palm pilot that was very finger friendly I just tapped in my data and it logged it all for me.

I want to find similar software for my Pocket PC. Preferably freeware (would have to be truly great software for me to pay for an MPG logger :-)

I only found 2 free programs and the one does not log and the other is garbage (instant crashing every time won't even load now)

would be nice to have something that "auto files" some default into from you and you can finger friendly alter it slightly for accuracy and that did not require the popup or slide out keyboard to use.

Graphing would be nice but not required.

integration with ecomodder would be amazing but I guess thats a fairytale :-)

does absolutely no one know of any ppc/windows mobile software for recording and calculating fuel economy?

palm no longer exists as a company, and the palm pilot is ancient history...

Try a notepad noting your odometer and fuel fillup

you can try the java soundcard mpg thingie, does the ppc have stereo inputs?

angelus I am talking about windows mobile - decidedly NOT a dead platform far from it.

I mentioned palm because when I used my palm I had great little programs for doing this. now the only program I can find crashes when I try to run it another is pay software and looks less impressive and the third only gives you one at a time data. No logging or anything like that.

dcb what in the world is that and how do I use it?

sadly no line inputs.

[RuHaSs]

Hope this help you.

SciLor's Fuel Blaster

[Nerys]

yeahhhh thats the ONE program I found and it simply won't run. It installed and loads one time then it refuses to ever load again. I tap the icon and it simply crashes without even showing anything on the screen.

I will try it again see what happens :-)

That is a java program that monitors the injector and speed signals via a stereo sound card and computes mpg type stuff.

I have an axim and I *think* the earphone jack doubles as a line in jack, unfortunately I don't feel like messing with it.

I found a program the other day that at least is WM6 compatible...OBDMobile. It is on Windows Marketplace. Link: RKlenka - View topic - OBDMobile is on Windows Mobile Marketplace! OBDGauge did install on my Tilt OBD Gauge , but I do not have a serial cable for it. I also looked at OBDPro and their adapters OBDPros , as well as BLueOBD blueOBD - bluetooth project based on OBD-2 , OBDKey OBDKey :: Wired and Wireless Automotive (OBD) Scan Tools ...but most of those require some dollars.
Are you looking for something to interact with the vehicle, or just something to log data into? How about tweaking an MS Excel spreadsheet?
Here are a couple other sites I've visited:
WinODB - Ordinateur de bord pour Windows Mobile
OBD-2 Vehicle Explorer Scan Tool Browser
OBD Diagnostics, Inc. - Diagnostic Software lots of stuff here...

[Nerys]

I am amazed at how little basic simple auto programs their are. ODB is only good if you have both 1996 or newer and a serial cable :-)

I never had trouble finding palm software. strange.
