No worries, how's your plane coming along.

Turns out my cooling was finally solved laying rads flat under cowl with reduced intake of the James cowl and the p port design is running excellently, 

Just clocked over 500 hrs last week.

Cheers

Cant find photos sorry.

I know the Water Heat Exchanger was 21" x 8” ~375in3 under the engine on one side in a ‘V’ configuration in I think a James cowl.

My understanding was that it ran hot. And due to the intake manifold (6 port Renesis cut off short) it would have not developed above ~150hp

G'day all

Just wondering if anyone has picks of the cooling on Ian's plane , for comparison

Cheers

Have missed the post somewhere

Bill,

Are the primary and secondary injectors the same flow rating?  If not how different are they?

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

I was afraid this would happen…

 

I got the new injector disable switches replaced today and while I was replacing them, I verified that both primary 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 that the cold start action does not turn on both sets of injectors.  My engine 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 engine ran a little differently and the mixture went to about 13.0.  When I turned off the primary, the engine died unless I immediately turned it back on.  I normally shut the engine down 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 but 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 my 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 because 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 above 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 repaired?  How long will Tracy be impaired?
