I have no way of plotting the advance curve Dave. What I plan to do is try it before & after the plug socket switch on my 12.7:1 compression FA-180 W/the 12mm carburetor. That engine is a good test to see if there are any gremlins present as if there is any internal arcing in the module/lead, it will show up as poor low speed/transitioning characteristics.
I'll also run it on my stock FA-150 @ 35* BTDC to give you an idea of what you should shoot for on yours.
