IOR is now mapped by output amount. So you need to have something that actually equals the IOR number in value. Say you want black color of your AO map to be IOR 1.5, and white color of your AO map to be IOR 3. Plug output map into the black slot of CoronaAO and set output amount to 1.5, then plug another output map into white slot of CoronaAO and set output amount to 3.0.

as ludvik said - AO by default produces values between 0-1, IOR needs values between 1 and 999, so you need to re-map the values, for example using the output maps
