The French CV-2 board is a TCI...Not a cdi and must have a 4 ohm or greater coil for correct operation!
I have one operating and using their software, you can edit things quite easily and it then produces a valid hex file which you must program into the pic chip with a pic programmer board.
I prefer Rob's old timer board using Nyemi's pic hex file and his Excel sheet to make the curves. Very reliable and small size board.
