It dont seem like its making much difference in rich/lean but with iac opening and injector DC constant i guess it would make it more lean. I moved %IAC Flow and AE still goes active and I can't feel a difference no matter where i move it. Anyway to make IAC more steady?

I set Lower IAC Limit and Upper IAC Limit both to 0 and it fixed the AE going active at idle and AE still works as normal. Can someone explain what these 2 settings actually do?
