Exactly
) - most cold start/running issues with SD are high revs until warm up. If driving around while the car is still warming up and depressing the clutch in to come to a stop (still rolling) the car will act like it's idle searching. Up and down until you come to a complete stop.After the car is at operating temp, issues are all gone.
Last time Aaron and I talked he was still working to come up with a fix. But it's been a while.
Aaron, was there any progress yet on resolving cold running issues with SD? Or still working on the solution? Or it has been official as nature of the SD beast?
Not sure on the RK tard of this one (rev limiter) - most cold start/running issues with SD are high revs until warm up. If driving around while the car is still warming up and depressing the clutch in to come to a stop (still rolling) the car will act like it's idle searching. Up and down until you come to a complete stop.

So I was trying to do some 7K rpm launches about 8 seconds after startup, backwards, out of the garage and up the driveway (that neighbor in the Legacy wagon was deep staging me!!!) and this is EXACTLY the problem I have!!!! Thanks Joey!
Aaaaaaaand we're done with sarcasm.
The cold start issues I have is that currently the car runs as if its in valet mode (confirmed it is not) and will not build revs past about 2,250 rpm and once it tries to go above that rpm the car bucks, sputters and acts a little like its in valet mode, but with some additional fun sounds. Fuel cut, boost cut? I dont know exactly what its doing (hence asking), however it does not drive anywhere near acceptable in the cold. You can use ~20% throttle to keep it below the 2,250 rpm area and creep at ~5-10mph. If you were to try and give 100% throttle it will slooooooooowly creep over 2,250 rpm then start the bucking/stumbling.
I have approximately a 5 block crawl at 20-25mph to get to any main road and the car wont achieve these speeds within 5 blocks (again, acts like boost or fuel cut with LOTS of stuttering and noises that you would hear from a high-class bus-stop skank earning some scratch). After these magical 5 blocks the car drives fine.
Fair disclosure: Car is warmed up in the toasty warm garage (adjacent to the furnace) for approximately 1-2 minutes prior to exiting the garage.
Werd! Need to patch up my cold issues as well. Mainly the "cranking the starter for two minutes trying to get it to start" issue. Only started happening in September when it started cooling down in the mornings.
