Data Logger Reccomendations?

Thats probably Dataq (www.dataq.com). I have their $15 data acquisition starter
kit. It has 4 channels of +/-10V analog inputs sampled at a rate of 240
samples/sec. What is that...a 4.2ms resolution? Includes Winblows software
that looks like a four channel o-scope. Has ability to log the data to the
harddisk for inport into excel, etc. Helluva deal. A little bit larger than a
pack of chewing gum. Took about 3 days to get to my doorstep after ordering
online.
I also use my OBD-2 scan tool (from www.obd-2.com) to select the data I am
interested in (or all of them) and sample those at a frequency of about 4
samples per second when the PCM ('96 Dodge/Chrysler) is not busy and only about
2 samples per second (way too slow) while PCM is busy (like WOT!). This is
while reading ALL sensors - maybe it would be faster when selecting less data.
But seriously tho - when it is easier to select ALL the data - why would you
not? - especially when troubleshooting. I wish I had the resolution of the
hardware solution w/the flexibility of the PCMs SCI interface/software
combination. The scan tool logs all its data also to a flat ascii text file.
Makes for cool trending via your favorite graphing tool.
Hope this helps - Latr,
Shane
