Hi Ferraristi! this may help some of you who suffered the same pain. I had a hard time with my 400GT automatic with a bad ignition system and I asked for some help on this forum and some nice guys gave me some advices, but all they proposed gave little success. The car started and runned badly while everything was new (plugs, ruptors, condensator). Finally, I installed two electronic ignition modules (one per distributor) and the miracle came through. When everything was mounted, I turned the key and the engine started at the first try and runned like it never did, probably since it was born (1976). It's a great pleasure to drive my beautyfull car with its engine roaring and accelarationg without any hole. The modules called IGNITRON contain a quite simple circuit where a microprocessor takes into account several parameters. The high tension is furnished through a MOS-FET transistor. The traditional ignition system is conserved but only a low voltage goes through the ruptor, which enhances its life time. The module are small (like a big matchbox) and invisible under the hood. I can give more details if needed. I CAN TELL YOU I AM HAPPY!
