Can you describe what will be needed for a SDS CPI2 (EI) user to add SDS FI?

1. That being said, if I were not already in bed with the Pmag, I may have gone a different direction if I were starting out fresh today.
2. The SDS CPI would be very high on my list....
3. Pros: Complete monitoring and control of the ignition from cockpit (without any 3rd party add on box)....
4. Cons: ....the user must provide some sort of backup power scheme.
....
...3. For me, this is a negative. I don't want to have to think or that while flying. At times there's quite enough to think about anyway, and for me, this is totally out of my comfort zone.
5. Ditto, this is a very large negative for me. I'm trying to keep my RV-3B project somewhat simple, relatively speaking...
If your true intent is to go EFI, then Ross' advice is sound: go with the EM-5 and run ignition only for a while. That said, I jumped from CPI to the EM-5 and can say that the coils, hall sensor and much of the wiring is the same. Essentially, all you replace is the CPI brain box. Considering the popularity of the system, there is a ready second hand market for these. You shouldnt get hurt financially going either way.
Our systems are all waste spark so hard to do on odd numbers of cylinders plus only a tiny market for Experimental radials so there would be a very long return on investment to develop new hardware and software.
I suggest that you make the unit blind behind the panel and WIFI the out put to a Droid pad that will show what the SDS EI is doing in graphs.Program the unit through WIFI and have as many programs as you want like for each altitude you fly,climb,and descent,LOP and best MPG.And that's just the start of possibilities.
Thanks Bob
"There will be voltage monitoring for the main bus power as well as backup battery health which we'd like to display easily for everyone so they have go- no go info on the panel and know what going on with the unit."
As someone seriously considering the SDS proposed backup battery solution, I would appreciate a voltage monitor option built into the system. The monitor in my field of view.
On the CPI2, we looked at doing a color MFD but the development costs put that outside the market for this device which is intended mainly to compete with the P mag, Surefly, Electroair and Lightspeed ignition systems. Most of these have no or no standard human interface available. Also, since programming is nil or minimal, it does not warrant such a display for just showing timing, MAP and a few other simple parametera 99% of the time.
The larger 12 X 2 display simply won't fit into a 2.25 round package along with decent sized buttons so it must be larger than that.
Appreciate the comments and glad you talked to Bill who's been flying and racing our stuff.
We're hearing as small as possible from most folks. We'll head that direction given the constraints of the 12 X 2 LCD. This unit will be at least 5 inches deep behind the panel though.
On the key comment, you can do a lot with a knob ie push/pull, left/right up/down detents, as well as the basic twist function - less space than arrow keys.....just a thought.
True but more complicated, expensive to manufacture, less reliable in our experience. .
Is it absolutely necessary to have the SDS CPI control panel pilot-accessible during normal flight? Could it be remotely mounted (like the forward baggage compartment in an -8?) I would consider buying this system now if the current control head could be remotely mounted (and wait for the smaller head once it is developed.)

... Has anyone installed the magnets with the ring gear in place?
And I wish that the CPI install manual had a few more photo of the magnet install process...

SDS CDI - This thread is a little stale. Can we get an update from SDS on the state SDS news.... What changes have been made in a last year and what is to come. Thanks.
