Well posting up my copy of speed density with all mods on e85.
I'll post up a copy with boost control added later right now the scalings are off and its not working like expected.
The full rom is posted along with the xml files so you can do a direct copy if you so please. I used 7zip to compress the rom enough so you'll need that or winrar to open up the file.
EDIT:
Updated the SD patched rom i have

I've noticed now that the temperature has dropped a bit below 50F that the cold start on this rom was a bit screwed up. I did a test by rescaling the rom with 0-60 load back to normal so I'm going to post that one up soon. Seems there are a couple tables that really need the 0-60load columns to remain the same for cold start driving purposes.

Its always best to keep the 0-60 load and 0-3500 RPM range as the stock scaling for driveability.

Just like MrFred I've found i had to add some decay time to the cold start to ensure it doesn't drop lean until the o2 sensor kicks on.

When I was running SD, I never had any cold start issues that I remember and still don't have any with my new 1250s, but I'm not on SD anymore. I do have all stock scaling for now as well.
I'm curious about your 'dropping lean' comment, though. You were going lean at idle? If your injector scaling and latency is set correctly and your two VE tables are set correctly, the idle should be good.

Seems most of the issues were simply how the load in the low range was scaled.

There was a weird IPW oscillation that I was experiencing only in a very specific RPM and map range.
Here is page 4 of the thread where I was testing and found the issue. I have posted and discussed it from that page on, but never found the exact cause.
All in all, it's not that big of a deal, but I would rather have it solved before I run SD full time, since this is my only car. I may still switch over anyway, since I have a 4" intake pipe and filter that I have been waiting to put on. But, I wanted someone to look over the code again to see if they see something that may be causing it.
