Good one..dick - like teaching an old dog new tricks.
RC, I'm sure the syncro-spark module is more expensive. The actual electronic components necessary to add the advance to the ignition module however is not. The cost you are paying for is in the programming and flashing of the ECM (i.e. development). Some of the modules, like the new Falkon are now adding features like in-flight RPM recording. There is really little or no cost in "parts" to accomplish this, just additional programming added to the flash.
