My aircraft has just turned 2 years old and we have flown just over 300hrs.
While there are a few other threads about CPI install,I thought I would share my experience as it goes together.
http://www.sdsefi.com/cpi.htm
When Ross first released the CPI (Coil Pack Ignition )and the early adopters starter showing their results,I was hooked . At last there was a true maintenance free ignition system that once installed and configured would do exactly what it was supposed to do without further adjusting or maintenance.
No moving parts at all.
As a LOP WOT flyer that sometimes use mogas,having the feature to easily adjust my timing by just one switch,sealed the deal for me.
The kit arrived and I started the install.
Crank Angle Sensor.
I decided to order the Dual Crank Sensor as I plan to in the future install the second ignition. You can install the sensor without removing the prop,but I wanted to "Armour Plate "all the wiring that was near the flywheel and this made the task way easier.
I used some 3/8" 5052 tubing left over from my fuel system to run the wires and clamp in position .
Coil Mount
While Ross has provided many options for mounting the coils,I had always wanted to use the space on top of the engine frame.With the coils mounted up high and the R/H Mag now removed,I can see my oil filter from the side for the first time. It should make the next oil change a lot easier.
I made a new coil mount bracket from some scrap 1/4" T6 alloy that I had.
It was a fun day in the shed with my new drill press and trusty jig saw.
A couple of adel clamps and it was rock solid mount for my new coil packs.
Weight
I weighed all components as I removed them and added in all the new parts.
The CPI system is 500 grams lighter than the Mag I removed.
Spark Plug Wires.
The Wires are the high quality MSD 8.5mm Super Conducter wires with the stainless clip on leads. These are cut to size as you install them.I sourced some cable clamps from the local hot rod shop to tidy up the install
That's all for now as I am about to start my journey to Oshkosh where I hope to meet some more of you and put a face to the names that are on these forums .
Any comments or observations are most welcome
