Hi Al.
 
If you engine is NOT running and the EC2 has power and your mode setting is in Mode 1 and you depress the program store button, the EC2 will simulate (generate) a train of injector pulses as if the engine was operating around 3000 rpm.  You should NOT have your pumps on when doing this or you will truly flood the engine.  When you press the store button the injectors will start clicking like mad -easy to hear.
 
Mode 8 does the same thing for the ignition,  engine off, mode 8, push store button. and the ignition will fire repetitively
 
These are really great from trouble shooting.
 
One thing that Buly mentioned and I confirmed today, IF you do have any fuel in the combustion chamber or intake manifold and your trigger the ignition simulation, the engine may fire and the prop may move or spin - so be careful.  Normally, you can made that happen, but using the ignition simulation mode you CAN.
 
Hope this helps.
 
Ed

Before, Tracy put in the injector (mode 1) and ignition

(Mode 8) simulation circuits

 

Enlighten me on these simulation circuits.  I know mode 1 is for manual adjustment of mixture table values, mode 8 steps the timing. What other tricks have been added?

 

And did I see someone (maybe Tracy) say that mode 6 adjusts the point at which the timing is retarded?  Mode 6 is ‘Secondary injector differential adjustment’.

 

Thanks,

 

Al
