EFI LIVE USERS - De acceleration I have my tune fairly good now but when I close the throttle to slow down there is not much de acceleration. What should I look at? Like driving down a steep mountain road, how can I get the most de acceleration effect to help keep my speed down? Thanks in advance for any help.

Check out your Throttle Cracker airflow table and try reducing the values for whatever speed you require. Also make sure the decay rates are where they should be.

Desired airflow an also give a cruise control effect on decel as well.
I would setup a log file and see what kind of air is being requested at that condition.

Thank you everyone. I'll work on my DFCO. For some reason I thought only the Holden Vehicles were able to use DFCO so I never touched it. I wonder if there is anything else I don't know. (that's a joke, I have so much to learn).
thanks again
thanks again
If you need anything else, let us know. We all are still learning.

Now, the car goes into DFCO a little more aggressive than stock where as before it wasn't kicking in at all. With aftermarket cams and their bigger durations, manifold vacuum isn't as strong. So, you need to adjust the enablers on DFCO to get that "engine "brake" feeling back.

We all love DFCO. Mine is super aggressive and on almost any time my foot is off the gas. Try UK $7/Gal fuel for focusing your fuel economy!
The holdens have Lean Cruise which sets them apart. Its based on achieving a set road speed and airflow after a base time has elapsed, then the mix is leaned out. Thats probably what you are thinking of.
