I didn't see much on the site about this, so I figured I'd post my findings..
I got tired have having cables in my way on our '95 neon to keep an eye on the car so I decided to try one of those CarChip e/x things you find at autozone. I got mine for $129.99 + tax.
It is basically a data logger (up to 300 hours) that can also get the CEL code and clear the codes.
When I got it, I plugged it into the serial port of my computer (it comes with a serial cable, but you can buy a usb cable) and set it to read rpm, coolant temp, o2 sensor 1 and 2 (my sensor 2 is simulator). It automatically reads speed. I also set the capture rate to every 5 sconds
I then plugged it into the obd-II port and drive to work..
When done, (when I got to work) I took out the carchip and plugged it into my computer again (it comes with software to read the data etc).. I downloaded the data and saved the summary report, and the charts of what I had the chip get (speed, rpm, coolant temp, o2 sensor 1 and 2). It also figures out if your accelerating hard (or extreme) and the same with braking.
The carchip e/x should work on any 1996 and newer. They say a few really new might not work but they will have new firmware for those. I "think" the 300 hours it can record is if you set it to record slower. Either way, from my figuring, I can fit about 25 hours of data with it recording every 5 seconds. I don't know what happens when you fill it up, I haven't even gotten close yet (it has 512 Megs of storage on it).
Here is the summary report of my trip to work (I was late, so I did speed a little out in the boonies and was accelerating/stopping harder than usual)..
Vehicle : 1995 neon
CarChip : K-1354-B
Start Time : 3/28/2005 6:59 AM
End Time : 3/28/2005 8:10 AM (Disconnected During Trip)
Duration : 1:10:09
Idle : 0:10:32
0 to 45 MPH : 0:27:18
46 to 60 MPH : 0:14:50
61 to 80 MPH : 0:09:09
Over 81 MPH : 0:08:19

o2 sensor 1 (upstream o2 sensor)
o2 sensor 2 (downstream, This is a simulator, I don't have a real downstream sensor on the neon)
You can see all the Red and Blue lines on the speed and rpm charts which show hard starts/stops..
I was getting an intermittant Cat efficiency CEL and you can see from the downstream o2 sensor chart that the simulator isn't dropping the voltage enough.
