What are you guys using for your warmup enrichment settings? I'm having a bit of trouble getting the car to run after starting in the morning. It always fires, but it takes 2 or 3 starts before it fires and continues running.
I'd just keep taking stabs at it, but I only get one shot at a truly cold start every 24 hours, which is a bit annoying.

MS Warmup Enrichment
You have two adjustments for cold starts in MS-II. Theres the WUE map and the ASE map. I'm using something like 150-170 percent WUE at 60 degrees coolant temp. I cant remember how much ASE I'm using, but you dont need a whole lot of that.
I'll check my exact settings at lunch, I'll post them up when I get back. They're not perfect, but they're getting better.

ASE %:
(Temp-Percentage)
0- 80%
10-70%
30-60%
50-50%
70-40%
100-20%
120-15%
140-10%
180-0%
WUE:
0-255
20-245
40-225
60-200
80-175
100-150
130-125
170-100
ASE uses an additional percentage of the operating pulsewidth for an amount of cycles after the engine starts. The amount of cycles in the taper isnt as important as the percentage itself. You dont need a whole lot of ASE or very many cycles in the taper, or at least I dont with my m20.
WUE multiplies the pulsewidth by the amount you put in. 100% is normal pulsewidth, WUE off. 0% means zero pulsewidth, engine doesnt run.
I havent done any work below about 60 degrees. I'll get on that this fall. I suspect its a little rich at around 60 degrees, but I havent worked that out very well yet. I suspect the ASE percentage is rich as well, but it isnt as important as WUE.
