Afterstart Enrichment?

[03Sierraslt]

I know a while back someone posted up (I believe ECTune) some tables to try playing with for lean hot starts. I am running 1barOLSD and anytime I shut if off and leave it sit for 15 min or so it runs extremely lean on startup and gradually comes back to normal after about 5min. or so. Where should I start on this to try to eliminate this? Thanks

I've been having issues with my idle as well...

With a stock VE table, the car won't idle without throttle until it enters closed loop.

With a 'tuned accurate' VE table, as per Wideband feedback, the idle is hit or miss... some days it will start and run fine... some times it will hot-start fine... others it needs throttle.

changing the VE table seems to be the easiest way to fix the idle, but then it's technically not 'accurate'.

I can only assume the VE should be left accurate, and other settings used to fix the idle such as frictional airflow, decay, and afterstart enrichment, but who knows... I've played with all the tables with limited success...

Using VE to correct Idle ... I dunno, maybe that is the right thing to do...

Have you tried the Open Loop Fueling table?

I glanced at that table once, but haven't tried modifying anything in there yet. It's hard to nail down when the issue is intermittent.

When I find more time, I'll have to play with it...
