Default Cold Start Enrichment Tuning

I'm heading down this weekend to get the NB out of storage and bring it back up to my house so I can tinker.

It's cold here right now (high of 38F today and that's as warm as it's been for quite some time).

I have an MS2E built by Rev, and I have his startup maps, but I have not yet tuned beyond that.

Is this an opportunity to tune my warmup/cold Start Enrichments, or would trying to tackle those before the rest of the tune is in line be a bad idea?

you must have a proper fuel and timing map before messing with those

That's kinda what I figured.. I know this is a really vague question, and the answer is going to be "it depends on a lot of different things", but is there a ballpark ambient temp that would be okay to try to get the car tuned?

If I throw the MS in there and it cranks and turns over, and is idling okay and not going super lean, I should be able to just let it warm up, then tune VE and spark, then shut it down and let it cool off, and then tune warmups and stuff more finely.

I imagine the basemap likely has enough WUE built in to at least get me going enough to let the car warm up..

yes most likely.

you want whatever temp is the most common in your area. most are in the 70-100 range

Thanks again. I'll wait until a particularly warm day and see if I can get it started. If I do, I'll monitor AFR very closely while it's warming up, and go from there.

I suppose I could also go for a cruise to warm it up under stock ECU power, and then swap out the ECU while it's still warmed up and go. !

What a thinker I am.

Or just let WUE analyzer get you 95% there.

That's the plan. But I need to tune my base VE table first, don't I? (almost positive the answer here is "yes").
