Also, in a separate post, Dr A cites +\- 0.5 mm3/stroke as the criteria. That makes me also wonder about the two negative values that exceed .5. I’ll note that all of those criteria are inconsistent with the .005cc value criteria on the diagnostic screen shot, but that could be a unit conversion error by the software cloner.
Ok. So I think I have got all this cleared up. And I think the results of this test are completely fine. Here's my supporting evidence:
1. The diagnostic screen gives a criteria of +0.005 cc/stroke as the replacement threshold. Converting to the units of the test result (cubic mm/Hub) and translating the German word "Hub" to the english word "stroke", gives you test results that range from -0.0006 to + 0.0008 cc/stroke. If you believe the diagnostic software didn't mess up the units, the test results pass (as pointed out by Cheyanne).
2. I quote Dr. A above, but found later corrections from him:
Jan 8th, 2008, Dr. A cites the criteria as +/- 0.005 cubic mm/stroke.
I was a bit too generous with that pass/fail threshold-my memory did fail me. The tolerance is +/- 0.005 cubic mm/stroke.
By this criteria the results fail on all cylinders by a factor of a 100 or so. Yikes.
April 3, 2010, Dr. A, after lots of unit conversion confusion back and forth, sets the record straight.
Lets start over here. The injector correction threshold should read +/- 0.005cc/cyl, not cubic mm/cyl.
That makes the DAD metric displayed threshold +/- 5.0 cubic mm/cyl. Any correction value greater than this indicates a possible issue with either the injector or engine cylinder or both.
Doktor A
Yay! A clean pass.
3. As a reality check, I used this screen shot:
https://sprinter-source.com/forum/attachment.php?attachmentid=22393&d=1270232634 and did some math to see if the units make sense. It specifies correction values on the order-ish of mine in the same units, and cites total injection per cylinder in those same units. Using the idle RPM and those values you'd arrive at a fuel consumption of about .26 gal/hr at idle. This number ballparks well against other idle fuel consumption rates found on this forum. This really just provides some idea that thresholds on the order of .005 cc/stroke make sense whereas 0.005 cubic mm/stroke do not.
Additional Note: I talked to Dr. A this morning (before finding a lot of this). His perspective was the test can be misleading (ie, affected by non-injector stuff) and I should be more concerned with having a properly seated OEM air filter from an engine killing perspective.
Bottom Line: The threshold for this test is +/- 0.005 cc/stroke. Less than that is acceptable. Mind your units as you convert from the reported values to the units of the threshold.
