Idle problem with SAFC II

[jonheslop]

I have a SAFC II and a GM maf with MAFT. For some reason my SAFC has to be set to +50 at idle when the rest of my fuel map is set between +5 and -5. Does anybody have any idea why I have to set my idle so high to keep it in the proper AF ratio? Thanks.

whata re you considering "proper" a/f ratios at idle?
are you usin a wideband?

What I consider proper is stoich. I have an autometer a/f gauge running off the factory o2 sensor. I don't have a wideband.
