I am designing a new micro controlled ignition system to address NLA
Tecumseh OH series engines, and a few HH models for that matter.

Since I needed to address a start/retard feature anyway, I can now
offer any desirable performance curve. So, what is it?

I plan a start at TBD for < 500RPM. Above 500, the first shift would
be to stock full advance. To squeeze out more power, I would imagine
another 3 degrees advance at 4000 RPM or so would be a good thing -
right?

This can either be a step or true curve - Any ideas?

This product will also provide a tach output so that any desired
automotive tach will work correctly.

Any other ideas of desirable features? Rev limiting? An LED to
indicate a given RPM? Redline?

I look forward to your thoughts...

Thank you,
