OK, a few other things that may help.
- You are running around 25gm/S of idle air flow. This is massive and leads me to think that you have either drilled a hole in the TB blade or it's a result of the idle airflow correction tables being zeroed out. The average commanded spark advance is only 9.9' while the commanded in the tune is 13'. This also indicates the engine is getting way too much air at idle. The commanded idle air is only about 7gm/S, which is a bit low IMO, so I'm assumiong there is a 6mm hole in the TB blade.
Unless you have a lumpy cam in there, I wouldn't have a hole in the TB blade. I am assuming you have a couple of turbos, though these should not alter the required idle air by much.- The Idle spark correction is not going to help until the engine speed has gone too far off. Then it's going to add way too much timing in a single hit and probably cause over correction swings. Going from 0' correction to -12'/+15' correction in the space of 16RPM change is not going to help anything. Even at your quite stable idle settings, the spark is going from 0' to 14' in the space of one frame. Much too much change IMO
- Idle Integral steps. I know that Hymey has run with these zeroed out, but I think that was on a very large cam, NA setup. I've never done this as I found it caused the idle to hang on deceleration and hunt badly unless everything else was absolutely perfect. I'd put some values back in there.
- The lean idle is interesting, especially for a fast restart. Can you keep the restart going to a point it idles OK? I'm wondering how long the lean condition lasts for. Actually, I just looked at your VVE. It's pretty bad, that's putting it very nicely..... The VVE shows that the engine will be running really rich just before the stall, at a guess, going from the information at hand, I'd say you were getting about a 4:1 AFR as it stalls. No wonder it smells like fuel.
So basically, I think there is no one magic bullet here. I'd start with making the VVE a bit more sane, then move on to base idle air and then corrections. I'd probably guestimate the VVE for starters, pulling 10% of the 400 RPM to 1000 RPM cells over 55kPA MAP. Then use stock values in the base idle air, Integral steps and Idle spark correction. Then fine tune from there making small adjustments.
