Emtron SL8 DBW

hey guys, I've just wired a BMW M50B25 engine with Emtron SL8 ECU, I've configured everything and it's working fine but I can't get the DBW configured, its a 80 mm BMW DBW the ECU should be setup as a custom PID so it has a 3D feed forward, proportional, integral and derivative gains tables i set the pid gains tables to zero and tried to adjust the feed forward table to get me close to my target while the DBW in the test mode but I couldn't get it work any one have an experience with this ECU can help ?
