Thanks Perry;
         I'd forgotten that you'd done this. It's worth looking at and I wonder if P4-5(EM2 data out) might work in this same fashion, but with more info?
        Are you still in Oz?

 ps. The link EC2Params.exe is not working?


I've got the EC2 output data format from Tracy and even wrote a program to display that data a while ago. Biggest problem is the voltage levels are not +/-12V rs-232 signals but 0/5 volt so you need to build a little circuit to fix that before you can plug that into a pc or pda. Here's some info at <http://casson.2y.net/Glastar/EC2_Tuning.html> And of course that data stream will not have any of the temp or pressure data that most people are interested in.
