As the temp drops, my warmup AFR...
Is getting higher and higher.
I'm uncertain which parameters to tweak in the warmup section to bring the AFR's back down.
My cold AFR's are up in the 17-18 range. Actually, I've been able to boost the % increase by water temp, but as I reach the top of that scale (160 degrees), I suddenly get very lean. I am idling at 14.8 - 15.0 once the car is really warmed up.
Any guidance appreciated!

Yeah, I know that.
My post wasn't very clear.
As it's getting colder, the warm up idle is getting leaner (pushing 17-18). This acute as I reach the top of the warm up enrichment temp (160 degrees), but before I'm at full warm (172 ish).
Once fully warm, I'm bouncing between 14.8-15.00.....
Does that make more sense?

I'm not doing a good job of explaining the situation here.
I am using warmup enrichment. It works as expected up until I hit 160 degrees, then it goes very lean.
If I add fuel to the cells, I run rich when I am warmed up.
If I bump up the warm up enrichment percent, when I hit 160, it steps back and is lean.
I can post a log if that would help describe the situation.
