Ignition System

Note to self: We should be able to fudge the standard CDI unit to run off the battery. http://www.vespamaintenance.com/elec...ork/index.html

For the Dry Lake Racer, we need a Smaller Flywheel and to save time we have decided to initially go with a total loss system that does not need anything from the flywheel except for a Hall Effect Sensor signal. Since we are making a flywheel, why not a complete ignition system. Since we are making a complete ignition system, why not make it a very cool one!

Here's what the system will be able to do:

• have advance mapped against engine revs
• have 2 mappings (one for each position of the power valve)
• have knock sensing capability (reduce advance if preignition is detected)
• vary timing while to engine is running via handheld control
• detect engine load and also adjust advance

Complete info on the entire system is covered in kc5442_Programmable_High_Energy_Ignition_System.pdf

Figure 1 (from the above document) shows an overview of the system.
