Helping a friend with his FC even though they are not in my experience.
I have a AP Engineering stock FC map. The Settings 4, three ignition tables are
drasticaly different than what a FD uses.

I have seen FC run well with the FD values. Does it make any difference?

 

I am running those weird values on my FC, which also uses an FD PFC (not an actual AP Engineering). it has 30 for all the dwell settings. I've played with different dwell settings before on the FC ignition systems. I don't notice a major difference. I'm currently using HKS Twin Power though so I'm not sure if that renders those values irrelevant or what.

Those ignition values may have been only relevant for the actual AP version, which does have some hardware differences from the FD due to the different igniter design between generations.
