Well, I might now have more experience! Same equipment, similar car, same procedure and it's what I'm seeing: don't see it on my car.Ok...I'll have to take a look at mine tonight, but I've never seen that late/early business. Somebody else with more experience than me can chime in here...but I've only ever seen the timing numbers (in degrees or the range of numbers that the ECU uses).
Yes. Yes. YesWas her car idling during this time, and was it up to operating temp? Requesting 4-7.5 degrees ignition advance is weird if so...
I am kind of side-stepping the entire notion of trying to make sense of the Cold Start Injector for now and just going along with it. Yeah, it's kind of confusing: in my head I just refer to it as "that other element/function being measured."I'm not sure why VW called the SOI valve the "Cold Start Injector"...that's not really correct imho. Some call it the commencement valve as well...but I've gotten used to SOI valve. In any case, the Cold Start Injector seems like a mis-label.
OK, thanks for confirming. Seeing as this is at idle I'm figuring that it's not all that problematic.According to the log data you posted for your car, your mechanical timing is slightly advanced. The ECU is requesting 0.4 degrees BTDC, and your actual is at 1.8 degrees BTDC, and the SOI valve duty cycle is at 2.8 (this is max retard). So, the ECU is requesting slightly more ignition retard than the SOI valve is capable of. You'd have to retard the pump timing slightly if you want actual to meet specified..
One other interesting point that I was trying to hold off mentioning, until I could understand whether it was something I was doing wrong or not, is that in my car I'm able to maintain Group 004 while manipulating the throttle (increasing/decreasing RPM): and it gets logged. In my wife's car VCDS seemed to just get stupid each time: it's the wireless Beta version, so perhaps I've encountered something that's snagging on a bug.
