Rough Cold Start - Logs Included

[The Ghost]

I have a rough cold start which only occurs for the ~minute or so. I'm running E85, but it seems worse than normal.

Looking at the logs, HPFP is maxed ("12" via JB4) during the rough period, but once it settles to"5" (~1k psi) the idle is perfect. The event that coincides with the HPFP drop (perhaps even solely the HPFP drop) is what I want to adjust to occur immediately from startup instead of waiting.

I've captured two examples below:

http://datazap.me/u/ghost/cold-start...1421&mark=1403

BTW, I've set the cold start duration to 0 in both the flash as well at flash time through MHD.

I was hoping to adjust the Fuel Target (homo) table during this area, but it appears logged load is low the entire time, so this table doesn't appear to be controlling the fuel pressure during this time.

Anyone experience and solve this issue? I'm open to suggestions.

The fuel pressure target won't help with a rough cold idle. There is JB4 logic for E85 cold start but that is only active while cranking.

There are some cold idle fueling tables that I think Jake was working on adding. I'd probably wait for those.
