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,=C2= =A0
Just clocked over 500 hrs last week.

I know the Water Heat Exchanger was 21&quo= t; x 8=E2=80=9D ~375in3 under the engine on one side in a =E2=80=98V=E2=80= =99 configuration in I think a James cowl.
My understanding was t= hat it ran hot. And due to the intake manifold (6 port Renesis cut off shor= t) it would have not developed above ~150hp

Bill,


Are the primary and secondary injectors the same flow rating?=C2=A0 = If not how different are they?


Did you get the signal recording setup working?=C2=A0 That would tel= l you what is going on.

I was afraid this would happen=E2=80=A6

=C2=A0

I got the new injector disable switches rep= laced today and while I was replacing them, I verified that both primary an= d 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.=C2=A0 My engine = operates as I described and not as Tracy says it should.

=C2=A0

With the engine idling at about 1400 rpm, a= nd 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.=C2=A0 When I turned off the primary, the engine died u= nless I immediately turned it back on.=C2=A0 I normally shut the engine dow= n by first turning off the power to the injectors and that is just the way = it acts.

=C2=A0

I then ran the engine up to 22 inches and t= urned the primary off and the engine ran just a little differently but made= no effort to shut down.=C2=A0 I don=E2=80=99t have much in the way of readings yet at that power because it is too hard = to hold the plane with just brakes.

I will try to get some better data by coars= ening the prop so I can hold it better.=C2=A0 I just need to get it above 2= 0 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?= =C2=A0 How long will Tracy be impaired?
