lets discuss DFCO If your happy with your settings, can you inform me on how you have them set. I want it to shut down a little better, seems its pushing to much My timing is going to the commanded closed tps timing but for some reason seems it's not cutting fuel. I might just have the complete wrong idea of what this is for.
To be able to set it properly you need to do a few test. And.be able to log your vehicle. First is you need to find out what the highest vacuum you are pulling when you let off the throttle from a high rpm. You set your dfco to a little more than that. Then you need to find out what rpm you want it to stop the dfco. After that you test for the least vacuum at that rpm coming from wot or from the previous test. These are the values you will have to input/change in your tune.
That's very aggressive. If you have it too aggressive that just means after coasting a bit, you'll need more gas to speed back up and will actually hinder mileage... If mpg is your thought process.
