I just thought I would show what the fuel map on the ST looks like from the e-manage. This map represents the alterations from the stock ecu. It shows fuel ajustment Vs Boost and RPM. The target AFR for anything below 0.4 bar is 14.7:1, so you can what changes in the map needed to be done to achieve this. - this is for economey. Above 0.4 bar to 1.8 bar the map target is 12:1. You can see where the airflow meter runs out of air the e-manage has to provide a whole load more fuel (from map sensor) to reach the target afr, infact almost double what the ECU would normally do as the stock map is not capable of going this far...
