Bill,


Are the primary and secondary injectors the same flow rating?  If n= ot how different are they?


Did you get the signal recording setup working?  That would tell yo= u what is going on.

I was afraid this would happen…=

 

I got the new injector disable switch= es replaced today and while I was replacing them, I verified that both prim= ary and secondary switches take pin 30 on the EC-2 to ground, so my wiring now seems to be correct.

But unfortunately I also verified tha= t the cold start action does not turn on both sets of injectors.  My e= ngine operates as I described and not as Tracy says it should.

 

With the engine idling at about 1400 = rpm, and the mixture at about 14.7, I turned off the secondary and the engi= ne ran a little differently and the mixture went to about 13.0.  When I turned off the primary, the engine died u= nless I immediately turned it back on.  I normally shut the engine dow= n by first turning off the power to the injectors and that is just the way = it acts.

 

I then ran the engine up to 22 inches= and turned the primary off and the engine ran just a little differently bu= t made no effort to shut down.  I don’t have much in the way of readings yet at that power because it is too hard = to hold the plane with just brakes.

 

Apparently the cold start system in m= y EC-2 is not working the way it should.  I need to get this repaired = but with Tracy out of commission, I don’t know how to affect that.  I suppose it is not too much of an emergency bec= ause this has been going on for a long time.  :>(

 

I will try to get some better data by= coarsening the prop so I can hold it better.  I just need to get it a= bove 20 inches and 4000 rpm to get it into that range and hold it for at least a takeoff amount of time.

 

Any ideas on how to get the EM-2 repa= ired?  How long will Tracy be impaired?

 

Bill
