"overrun throttle" and "overrun fuel cut delay"

[lorem]

From the "rev hang" help page (https://www.hondata.com/help/flashpro/index.html), I see that "rev hang only affects manual transmission vehicles", but I do see parameters for "overrun fuel cut delay" in Accord 2015 V6 AT's calibration.

So I'm wondering what's their effect on how the AT car drives. It seems that if I set "overrun fuel cut delay" too low, the car will be really jerky when it downshifts. But what's bad if it's too high? Can anybody tell me what's a good number for "overrun fuel cut delay" for AT cars? Should I just leave it at its default (130)?

Also I wonder about "Overrun throttle opening" for AT cars. Since there is no option to turn it off, does that mean it's always on?

Thanks.

You should just leave these as default as there is no good reason to change them on an automatic.

Thanks a lot. I was just wondering if they change how the car handles. I'll just leave them as they are then.

For purely geek's interest, can you let me know is it the case that the "overrun throttle opening" is always enabled for AT cars?

Yes it is always enabled.
