Thanks to Bob, Steve, Jack and all you guys that have offered some EXCEL help.  Here is the basic protocol of the data files it needs to use.   The crude spreadsheet I have already written is too large to post, not because it is complicated but only because of the large number of cells. 

The basic idea is to display the data in a horizontal line graph with the horizontal axis being time and the vertical axis being the value of the data.  My first attempt just has all parameters on a single graph but it would be better to have separate graphs for related groups but still be able to relate them in time. 

I'll attach a sample data file if you want to play around with it.  This one is a short one so that it will go on the list server.   A full one hour log was too big.

There are a maximum of 3600 data blocks (1 hour)  in a record.

The parameters in the data block are in the following order:

  1. Coolant Temperature
  2. Oil Pressure
  3. Oil temperature
  4. Coolant Pressure
  5. Altitude
  6. Fuel Pressure
  7. Left Tank fuel level
  8. Outside air Temp
  9. Right tank fuel level
  10. Air / Fuel ratio (Mixture)
  11. True Air Speed
  12. Air / Fuel mixture 2 (not used on most installations)
  13. Battery/Alternator voltage
  14. Fuel Flow (GPH)
  15. MPG (miles per gallon)
