Dragonball Posted November 6, 2004 Share Posted November 6, 2004 Originally posted by Ian C The addinj map can't trim duty cycle, but other than that you are right. The single adjustment applies to all airflow values that are encountered at that throttle position and RPM - so it'll be increasing the signal by the same amount at vacuum, overrun, cruise, and various levels of boost. The fuelling requirements for these scenarios varies quite a bit though, and although a one-size-fits-all airflow adjustment value is OK for a lot of load sites, it's not OK for quite a few important ones. If you tune airflow only you have to play safe and fuel enough for the worst case scenario - full boost and a bit - and lump it when a little bit of boost runs uber-rich as a result, or even cruising eats more fuel than it should. This is why I'm no longer a fan of the Apexi units for big jobs - that and their lack of load sites in the first place. And also I guess some people's definitions of "mapped" and "running OK" differ to others -Ian Jeez Ian...have you ever thought of running for president? You are frighteningly good at this scary shit!
