tday i played with the timing.
this is the current ign map in raw & filtered values


looking at the map view while i alter the raw values i found that values:
0-63 = 0 to 63deg btdc
64-128 = -64 to 0deg btdc
128-191 = 0 to 63deg btdc
192-255 = -64 to -1 btdc
the dizzy is 14deg retarded so need to lower the whole map by 14deg
i can't decrease the whole map cos the cells at 600rpm/100% are already near zero. so i'll have to go up by 128 to get into the next +ve region


now i can lower it all by 14deg to offset the dizzy


the idle timing needed increasing back to 15deg


so i uploaded the new map, advance the dizzy till the consult 15deg matches the strobes 15deg, lower the idle back down to 750rpm and she idles at 15deg.
i blip the throttle but seems really sluggish above idle. check the consult and even though the filtered values and the timing value in the map view says it should be +ve 21deg at 1200rpm etc the consult display & strobe shows its actually running the opposite -ve 21deg etc hence no power
ffs, i'll leave it back to previous setup for now
