AC-CDI Suzuki DR600

A adaptation from   Features Based on : PIC16f628 v6.5 for singlecylinder. 1 advance curve programmed. No RPM limitation.   Introduction. This adaptation was design for a DR600 SJ model 1988 that use a CDI with 2 sensors, this adaptation does not work on previous models with only one single sensor. The working is quite similar to the XT 600, just reverse two wires.. Be aware that the pickup .
