Does the attached ignition timing map look about right, at least as a
starting point?

And are the positive numbers BTDC?


Jay

Yes the positive numbers are BTDC.
Sounds like the negative numbers are ATDC.

What rotary engine are you using and what turbo charger
are you using?

What kind of computer are you using?
Are the manifold pressure numbers in inches of Hg?
They appear to be.
