Jake, I like all your ideas, but as you say.....your the programmer and not a user (?)
You need people who knows how programmable CDI's are working and why they are working like they do.
Thats not the only problem, you need also people who knows how engines are working, ignitiontiming, porttiming compression, exhaust aso.
John, Charlie, Nyemi (maybe I forget some-one) know wat they are doing, but the rest are users.
They fix the CDI to the engine and hope the CDI are working......they don't know wat they are doing or why they are doing.
A programmable CDI is not for normal users, but for people who want to get more from the engine.
Thoose people are tuners and use the engines for real races or other advange use like bikes and mopeds.
If a normal user test or use a programmable CDI I can ensure they call it sh*t and want there money back.
You can write a manual from 100 pages, but they don't read it......I know [8D]
My advice, never sell your designe by your self but doit by company or store and only if you are sure your designe works 100%.
Other advice, buy a small engine and put the CDI on the engine to test your software in real.

I send you a PM
