here is the 2 nd measurement

The AIC device is connected . As the WUR boost line is still activated, The AIC controller was programmed to act between 4500 to 6000 rpm only...
I made 2 very simple maps in order to stabilize the boost level ( no adding boost beyond 6000...) and to get more fuel on top end . ( about 40% duty cycle on the frequency valve).




The boost level is correctly achieved. ( about 1 bar until 6000 RPM). As mentionned I do not maintain any boost gain above 6000 RPM. ( so it drop suddenly ) .

However , the fuelling is not correct and it is too lean above 4800 rpm ( almost 13 ) . (We can noticed the AFR comes back to 12.5 while the boost decrease above 6000 RPM) .
