A day and a half and 90 miles after turning off the IMA battery the FCD is reading 72.1 mpg and rising for this tank (which started with a bunch of recals for the first 75 miles). Hopefully the next 550 miles will give me time to bring it up some more.
Doubt that I'll ever pull off the numbers I was seeing with the assist/autostop, but I should be able to maintain 70+ mpg tanks even without the IMA functions.
