This completely supersedes our previous transistor assisted design and employs a high temperature microcontroller to control the switching transistor and sense the trigger signal. This kit can be connected to conventional points or relecutor ignition systems. Its 4 to 22V operating voltage, fixed 0.9ms spark duration and tachometer output are just some of the many features. A small investment that will pay for itself many times over.
• Kit supplied with diecast case, PCB and all electronic components.
