Paul,

 I looked at the information on the web about TDC and how the E
 shaft pulley is marked at 5 degrees and 20 degrees BTDC and
 has a unique hole pattern  to ensure one position
 installation.  It was also stated the when the keyway is at
 the 9:00 position the E shaft is at TDC.

 From that I can make the 2 tit tooth wheel.  2 sensors 180
 degrees apart will provide the signal for ignition and I
 assume you are going to use that for initiation of firing an
 injector?  Do we need another wheel for the tach signal?

 Are you are using MAF and tach to determine injector pulse
 width?

 The system will be 3 boards one on each rotor with the 8 A to
 D channels used.  The third board provides the interface to
 the PC.  Could you use the optional channels from both rotor
 PCBs to increase the  different types of data to display?
 Just trying to keep up with the design.  Thanks

You won't need three boards. There will be one USB port board per board so at the
moment you can get data from only one rotor at a time. As we go along that may change.

I'll know more after I get the software working.

I am focused on BASCOM right now. It's free for small projects and the IDE looks
simpler to use than the Mikro IDE. I have the demo program for both. BASCOM is half
the price of Mikro if I decide to buy the full blown versions.
