Why a Programmable CDI ?

Why a Programmable CDI ?

Well if you are converting an engine from glow to gas like I am (ASP 0.65FS) then you’re going to need an ignition. Another reason is that most OEM gas engine manufacturers don't set their ignition timing or timing curve to an optimized setting or one that produces max power. Why? Well they have to provide warranty for their products and that costs money. Another reason to have a programmable ignition is that if you change props you are changing the load and how that load is applied, so if you can make your own curve then you can make a more useable power curve. You can even save fuel with the right carb mixture and timing. A leaner mixture needs less timing and a richer mixture needs more timing. So what can the standard CDI-2012 setup do ?

• Can hold 2 different timing curves
• You can switch between those 2 curves in-flight
• Use an Excel sheet to produce your timing curves and the actual code
• Kill switch can be used in flight

We are working on a way to do in-circuit-programming and if you want to help then please do.
