Well Mr. Fly42, as I see it, you are complaining about something not working that you haven't even built and tried!
If you need proof that it works, watch my video of it actually working before you say it doesn't work. As for the project itself, it is a "do it yourself" project. Which in turn means, you gather the parts, you make the circuit board, you program the chip with the provided hex file, then and ONLY then, you decide if it is not the project to fit your needs.

If free is not cheap enough for you, then I would strongly suggest that you go out and spend your money on a commercially available ignition that fills your needs. I know you can't get RcExel to change a curve for your engine because you think it won't work without ever trying it.

I stand my ground in defense of everyone participating in this DIY project.

John
