Dwell / Duty Cycle Q.

[camron at worldaccessnet.com (Camron D. Crouse)]

Checking duty cycle values for 2.0 16V Scirocco w/CIS-E +TT fuel 
enrichment module.  DPR current successfully set while at full running 
temp, 10mA +/- 1mA with a brand new auto-ranging multimeter.

Trying to accurately check duty cycle.  Bentley describes disconnecting 
crankcase ventilation hoses, but the illustration seems to depict a 
fuel-distributor-on-passenger-side setup, and the hoses don't quite 
correspond so I am unclear on which crankcase hoses I actually 
disconnect and at which points (Bentley illustration shows a ventilation 
hose with a nippled T in it, but I have no such T).  In addition, the L 
nipple to the intake boot does not fit snug while in the test position.

Do you folk make this check with hoses disconnected or in running position?

BTW I am going through DEQ tomorrow so that I can bring my registration 
up to date.  Tuning for passing E-check, so stock settings wanted...

TIA!
