Does anyone know the difference between the A and B for ignition, Fuel mix A,B,C, ect. I don't like not knowing.

 

So nobody knows?

I am trying to fine tune my lower rpms and I want to fine tune these tables without making 150 flashes on the ecu.

 

The two ignition tables would probably be normal and high detonation. It should switch to high det. when it detects excessive knock. I'm guessing B would be high det. but I don't really know how cobb labels them. As for fueling a/b/c I have no clue. Osiris has only one compensation table and one target table. No a/b/c tables for fuel.
