What is DFCO????

DCFO is a PITA. It is hard to figure out what to set it to on a cammed car.

Well let me know when you do. Because I can't figure it out either. Personally I feel that it might be somehow related to bucking under 0 TPS that I get when coming to a stop. I'm just not too sure where to start to look.

I thought that too. I know if you are in DCFO there is no bucking on decel, but it is hard to control. Try adding 10 kpa to your entry and exit map and see if it helps you. Also add +100 rpms to your entry and exit RPM, that helps a little too (I think).

Well this is better direction than I had.... lol!

I will give this a try..

The only bucking I have is at 1300 - 1600 rpms..


I added 2* of timing to my 0.28g/cyl to 0.12g/cly this seemed to help, but I only did it yesterday so I will have to give it a day or two more to know forsure if it is gone.

if not I will try this.

There is a lot of information about DFCO in the help files.

I just ran across this old post while trying to answer some of these questions as well, I have to say, the help file to me was not very useful and seemed really dated from my newest version.
I still have no clue how to set it. All I want is one, not to coast-down real lean and no big engine brake feel at 65mph when I lift the throttle or kill cruise. I just want to coast as best possible.
