How’s your plane flying now? All sorted out?

Hi Mark

 

My GSuper II RG is powered by a 4 port Renesis EC2 EM3 RD1C and MT Prop.

 

My EC2 software has the Staging Point locked at 20 inches and I discovered the small Primary Red injectors were saturating before the larger Blue Secondaries switched on.

I could have raised the fuel pressure a little but ended up changing to 4 yellows which works well for me.

 

I’m still fine tuning the cooling system, reducing drag and increasing speed.

All the best with your build.

So after a few years hiatus of working on the project, I am back at it.

Glasair Super 2 with 4 port RENESIS.

 

Feels good, except I cannot remember all of my plans, nor some of the decisions I made. 2 sets of bell mouths for the intake, obviously one was first… and one was “decided on”

 

I purchased my EC-3 back in 2012. I believe at the time I asked Tracy for RENESIS engine with stock injectors and LS1 coils. Searching through the archives, it seems Finn Lassen found that the EC3 is not programmed correctly to represent that? Or maybe I misread it.

 

All my electronic pieces are still unopened and no work has really been started on installing any of it. I am working on getting all the ancillary systems such as intake, exhaust, oil and cooling setup. 

 

So a few questions for the group:

1) ditch the EC3 and EM3 altogether (and provide it to someone else as a backup) Start acquiring/learning SpeedUino or some other system?

2) continue with what I have (is there some way to validate or change the programming of the EC3?)

3) unrelated: Anyone made the swap to yellow and blue injectors for RENESIS and are happy with their decision? Or stick with red and blue?

 

Appreciate any insights from others' experiences as I get back at this. 

 

Warm regards,

Mark McClure
