Hi,  
in Afterstart State the idle valve goes to zero and engine dies.  
Any ideas?

Thank you

Please publish your base map. I will test it on the simulator.

hi,

today we hit the dyno  
works great.  
but idle is not working right..  
Do you need the Dyno log for your research ?  
At the end of August we want to test on racetrack.

Best regards

You ahve enebled Fuel Cut idle control.  
Set it to disable and then airflow will be controlled as intended.
