Startup AFR commanded vs actual

[carneb]

I've noticed on cold startups that my commanded AFR is around 10 but my actual is around 12. As the car warms up the actual converges on the commanded value. Should I be worried by this? Should I try to reduce tables such as Startup airflow correction or Startup friction airflow correction to richen it up a bit? Or will doing this just increase RAFIG to compensate and keep the idle speed constant?

I let my PLX300 warm up to read "Air" on the display before starting and I think my VE table is pretty close.

I have a PLX M-250 (no display) but I suspect part of may be that it is not completely up to temperature.

I also richened up the After Start Enrichment stuff. 10:1 is just a bit rich IMO.

Same here, I think its initial prime and afterstart enrichment etc, which cause the initial disparity.

If you are running in SD, this seems to be a common problem. There was an indepth thread on this on LS1Tech a few months ago. Not sure what the final consenus was.
