overrun fuelcut issue, flood engine?

Recommended Posts

Hi, more problems due todays tuning.

overrun fuelcut emptys the fuelpressure when it is on. Have tested all hardware and ther are no problems this far.

Is it any known issue?

The engine stalls directly after a overrun fuel cut episode and are hard to start right away. Looks like it is overflooded on the exhaustgases.

Here is a log file with the fenomen. Look at overrun fuelcut and fuelpressure, also on lambda cylinderbank 2, that is rich if i force it to be alive.
