April 26/20, The plug wires are connected and the CPI control unit has been wired up. Initial timing of the CPI was completed as outlined in the user manual using a timing light and once completed doesn't have to be done again.
Below you can see the prop bolts with the trigger and sync magnets installed into the ends of three of the bolts. The magnets protrude 3/16 inch. This is a top down view . The wire is a extension of the center line of the engine case to enable using a timing light to set the initial timing angle.
The photo below shows a refinement of the timing mark (10 deg BTC) on the crank. I placed a piece of black vinyl tape on the crank and then a small white piece on top of the black. This trick was advice given from a friend at the airport who has installed the SDS system CPI units a few times.
Below is the CPI programming unit temporarily hanging on elastics during my initial start up, testing and programming. You need access to the programmer to monitor some settings and adjust a timing parameter. The ignition system company recommended I install a vacuum tube for the programmer to get a major benefit. I did not have a vacuum connections on my Revmaster throttle body so installed a nipple on the main intake tube right behind the T-body.
Calvin I’m installing the same system on my dragonfly. I was wondering what your magnet position is set to?
