Harry, the 123 uses a transistorized trigger, so the very limited dwell times of points type distributors does not strictly apply to the 123. Plus, it's programmable from your phone.

Did you forget about converting from the six pin CDI, which generates the tach signal?
Remember, the 911SC's tach would be damaged with a signal directly from the coil.
