> 409-292-0988 has a 8 ch. 12 bit A/D, 2 12 bit D/A,
> 8 ? I/O lines, 2 current sources and a current mirror 
> for $99.  that uses printer port.
> I bought there 1st model a few years ago, was just
> 1 ch. 12-bit but never have used it.  I think they
> also have kits.
> The filtering circuits and sampling times would be helpful
> to document.  The O2 signal for me has been fairly clean
> with no filtering, I get good readings hooked up straight to PIC.
> A GM TPS was very noisy.
> I was looking at O2 sensor readings for cyl. misfire, but
> but thru out all data due to lack of interest and disk space. 
> There seemed to be some patterns, I would like to do something
