David: The empty space behind my panel is VERY limited because I have a LOT of Dynon stuff. So, I mounted the controller on the forward side of the bulkhead forward of the instrument panel. Not the easiest to get to with a slider, but it works. I mounted the backup battery forward of the fuel selector. I installed an Airflow Performance fuel pump forward of the fuel selector last year by making a plate that fits between the two floor stringers forward of the fuel selector. This plate is flush with the top of the stringers and attaches with screws thru the side of the stringers. The pump sits on top of this mounting plate. I lengthened this plate and mounted the back up battery on this plate, forward of the fuel pump. Everything is covered by a sheet metal console that attaches to the plate. I covered this console in black carpet to match my floor carpet and the console is barely noticeable. Bruce Estes

Toolbuilder: I don't check my P.M.'s on a regular basis so sorry for not getting back to you. I really prefer email as that gets checked often. Compressions are stock and I have the dual controller. Bruce Estes

Bruce - thanks for the detailed write-up, it has given me some ideas.

Did my first flight today since installing the SDS CPI-2 electronic ignition, using only one system initially. Almost everything worked as expected, no surprises. Only flew for about one hour. I still don?t have a tach signal on my Skyview from the SDS, but Dynon is going to help me tomorrow. The SDS is not plug and play like some other electronic ignitions, but has MANY features not available on any other system. Barry and Ross from SDS have been great to work with on this installation.

Great news Bruce! Glad it worked out.

There is insufficient resolution with the triggering setup and there would be other hardware required. Something like this would have added 6-12 more months to development and product release on something which already took a year more than expected to develop test and test.

My CPI-2 is running but I have an issue that Dynon and SDS have not been able to solve. I get a 0 RPM reading from my Skyview when I kill the mag. I am running one side of of the dual SDS system, retaining my mag until I am comfortable with the SDS system. Has anyone who is running an earlier SDS CPI system and Dynon Skyview run into this and how did they solve the problem? Any suggestions will be welcome. Thanks, Bruce Estes

So when you ground the magneto, you get no RPM reading on the Dynon? Is the magneto the source for your RPM signal?

Dynon reads a mag/ignition signal. If one signal goes away, like a mag check, Dynon immediately reads the other signal. When I kill the mag during a runup mag check, the Dynon reads 0 rpm. There are two inputs to the Skyview.
Per Dynon, I?ve tried both of them. There is only one output from SDS. I tried with no resistors and then tried with resistors recommended by SDS. No success. The Skyview config options only deal with pulses per minute so I think Ishould get something, even if not accurate, for a tach readout from SDS to my Skyview. I am open to any suggestions to fix this problem.
