Datalogging with a Palm...it CAN be done!

as long as you have it, please try it. The Serial cradle bumps the TTL signal up to RS-232, so it *may* work using that. If you dont want to bother, you can send it to me and I'll play with it on the MSPNP 
EDIT:
Nevermind, Looks like one guy on MSEFI got it to work, he had to yank out the TTL signals from the CPU before it went to the RS232 chip.

EDIT Again:
After further research, I'm pretty sure this is everything you'd need for the Visor through the MS serial port:
RS-232 Visor Specific Serial cable (or hack a cradle). These have built in chip for TTL/RS232 conversion. This chip needs 5V to operate it, you need a way to power it.
Null modem adapter or swap pins.
I will probably look for a pIIIxe, but something about rocking an old-school VisorPhone appeals to the geek in me.

Here is my PalmLog Environment Setup, as requested. It works for me on my MSPNP MM9093, but I cannot guarantee the values. In fact, I can't remember how I got all of them. I did a bit of reading on the msefi forum.
MAP-Off: 9.0
Map-Sc: 0.984
C-Bias: 2490
A-Bias: 2490
Cool-A: 1.222E-3
Cool-B: 2.776E-4
Cool-C: 4.196E-8
Air-A: 1.506E-3
Air-B: 2.250E-4
Air-C: 1.247E-7
WB-Off: 10.00
WB-Sc: 2.00
RTU Char: R
Bytes 39
I have my "boost in psi," "Fahr," and "diywb" boxes clicked; I am using the Techedge diywb.

Wow, thanks, I'm glad I asked you for yours. My values were different. I used the therm and mat factor values from the config file that was WITH AFM, not the values from the WITHOUT AFM file. Confused me for a minute, but I'm glad I was able to see your values and catch my error. 
Still working on the MAP scaling... I think I have it nailed. Haven't built the null modem adaptor yet to check it though.
I think my values will be the same as yours, except for the MAP sensor calibration:
MAP-Off: 20
Map-Sc: 1.490
Not 100% on those values yet though.

So I made a null modem adaptor out of a pair of DB9 ends I had. And guess what. Without looking, I made a M-->F adaptor, like what every other device gets... And this piece of crap needs a M-->M adaptor. 
I don't have any more male DB9 terminals.

btw: Have you looked at how the palm transfers a datalog to the computer? The data is sent via batch mode to MLV while essentially "synchronizing" the palm via PalmLog. I'm not so sure you'll be able to just pop the CF card out of the palm and read the datalog file from the computer. You'll have to figure out a way to translate the raw palm file to datalog file on the computer (replacing the palmlog synch. built-in translation).

Started doing this myself recently. Freaking loving it.
However, I'm unsure on the AFR readings at the moment. For the LC-1 what would the WB-Off, WB-Sc settings (or any other settings) be for its default setup? Right now I just have "Other WB" selected with WB-Off: 10.00, WB-Sc: 2.00. The readings seem close they seem but perhaps a little rich.
Any ideas?

yeah 5V @ 20:1, sorry, my mind was somewhere else when I was finishing hte message... because when I was reading your post, I realized the solution to my map sensor scale problem.
