I always wondered why honda took the timing information (C72 / C77 / CB72 / CB77) from the camshaft. It's not accurate, there's always a dwell due to cummalation to all tiny errors, and it's not much cheaper to build.
But it could have something to do with the powerconsumption of the ignition system.
I builded in a CDI ignition and positioned the Hall-elements on the generator rotor.
Each cilinder has it's own sensor, so every 360 degrees of the crank (per cilinder) results in a spark.
50% of the sparks per cilinder are useless because thers is nothing to ignite.
The power surge is twice as high for the total system (logic) compared with a camshaft timing.
It seems that this is a little to much for the standard electrical system and we all know that this is a week point already.
It'just a tought, as a system engineer I always wonder why and wich arguments decisions are based on in an engineering proces, and I can't stop thinking as an engineer after shutting the door at the office.
