SAFC ll settings. Help!!

[nsn240]

EDITED for content instead of making a new thread

I know the safc has a ton of features and stuff to tune with, but im not really good at using all of them yet. I was trying to figure out it i could use the safc to "tune out" some little problems...

When i let off the gas, in any gear, so i can coast, the car jerks around and rpms bounce around. Can i tune something so it will keep constant fuel at low throttle? (similiar to the decel settings i have set up for the atmospheric bov) so the car doesnt have a fit when i let off the gas.

Also, today driving around... when you come to a stop, the rpms drop very low (~500) and then bounce back to idle. I just changed the decel/open bov settings earlier, so i havent tested if that fixed it or not.

any help would be appreciated
