Doesnt seem like a bad deal.

If you are looking for a science project, its a good start. Think about adding accelerometers, RPM signal filtering, and it starts to get complicated. Forget GPS - not enough processor grunt to be useful.

It will certianly work for very limited applications. Most guys want something that has been configured for track applications and has appropriate post-run analysis software. Entry point for this class is slightly south of $1K. Like many things, it can be built far cheaper IF you have the time and interest in such a project. More power to you if so. If you get it right, some listers are likely to want one.

I was thinking real simple like the wide band O2 output (0-5 v)
TPS signal, AFM signal, Boost via a MAP sensor. Just for tuning.

I have used the older 8 bit version of this product before. The product works well, but is very basic. It has no low pass filtering to reject noise or Aliasing (it is OK if you have no clue what that means). The current 10 bit version as implimented will have about the same resolution as what our 8bit DME/KLR can measure. They also have a 12 bit version for more money. I would recommend you to shop around their are 10s of companies that offer this kind of product now. The most recent bunch are USB based, which allows a much higher data throughput, and are a much less touchy interface.

PM me if want more guidance.

So you just tap this into the DME??

And what can it datalog???

I wonder how complicated their input format is - if you can do it in raw C rather than Active X you coudl put it into the serial port of a PDA rather than a laptop, making it MUCH more useful.
