Hey folks I am looking for a good stand alone scantool, that can datalog / stream data from O2 Sensors, Timing, RPM, and Knock... Anyone have a solid product in mind?

 

Is there a particular reason you need stand alone? I have this:

It's pretty good. I have the PC version, which I just plug into my laptop. They also have a PALM based system for use with anything that runs on the Palm OS.

 

I also use the AutoEnginuity ScanTool and am happy with it overall. I looked at most of the other PC based scantools available. Although it appears to be one of the more expensive scantools ($250), most of the "cheaper" systems require additional adapters and/or fee based software updates that increase the costs to the same or higher level for the same functionality.

 

I have one of these- $83 and the software is free

Plus the guy provides lots of code assistance if you want to program your own application. I made a simple program that allows you to datalog any combination of sensors on a laptop and made a simple version to run from a PDA

 

I dont have a laptop nor do i own a PDA... so a stand alone unit is pretty much required.
