duty cycle/open loop under boost

[Ameer Antar]

I remember you had gotten 65% D.C. when under open loop. The Bentley says 
80% below 68 deg., but reading thru the Bosch CIS book, C. Probst says 60%. 
So there is some discrepancy. I would tend to trust the Bentley, but maybe 
this just means it's not a huge issue...

Also, I'm still looking for conditions where ECU goes open-loop. Probst says:
-low coolant temp
-invalid o2 sensor output
-WOT
-coasting [decel valve on...not applicable to my A/T, though]

but I can't find mention of open loop above 1.1 bar in Bentley or Bosch 
book. If anyone has info, I'd appreciate it as it could help understanding 
what's wrong w/ my car's CIS. Thanks.
