You can avoid this problem entirely by installing a clutch switch. I often use mine on the highway to avoid Regen+DFCO drag and just get DFCO drag. It also prevents hidden background charging of the IMA battery.
An OBDIIC&C gauge will let you see background charge.
EFAS would let you easily engine-off-coast at highway speeds if you really wanted to turn your car into the Space Shuttle, but the clutch switch and OBDIIC&C will help a lot with the issue you're mentioning here.

I didn't realize this could be done!! I guess I finally have a compelling reason to install MIMA. I don't have a plug-and-play version, I've got like a box full of extras to make a kit for it that Mike sold me at a discount. I never got around to installing it because it looked like a big job.
