6.0L E38 1st start of the day rough idle and dies

[cynight]

The engine will start fine then run rough for a few seconds and then die the 1st start of everyday or if it sat for 4-5 hours, if I restart it will idle fine. I'm currently running E70.

6.0L, RHS rect port heads, 230/242 @ .050" 113 LSA, Torqstorm supercharger, and long tube headers, FIC 660 injectors.

I have adjusted B5104 and B0138 with no luck.

Any help is greatly appreciated.

have a look at this.

just be careful with your B5112 your adding timing in based on PE.

Sorry for the delay, I was out of town last week. I tried that tune and it ran a little longer before dying.

I noticed in my 11NOV data log the timing drops 4-5 degrees during the first start vs the 2nd start, I haven't found a table that might cause it or if there is another issue.

I'd think the timing would raise as the idle was dropping below the desired RPM but it appears it's doing the opposite.

I zeroed out B5112, it was left from the L99 base tune. The big pain is having to wait 4-5 hours for the issue to return.

Thanks for your help
