thanks for the answers
-for THe CR, I'm am under 8:1 because I have grind/enlarge the headchmaber from 47cc to 56cc and my headhgasket is 1.4mm ( not 1.2)
-and yes for the AFR I have to grind and/or adjust the needle as many times is required to have good result

-For the ignition map with 123, i have your schematic : but i don't understand why there is 15° to begin in 0 RPM ( red line/low comp) , its suppose to be at idle (800rpm)??
