Parameters Required to Trigger DFCO?
I just recently finished putting my car back to stock and was looking forward to having the DFCO feature again. However, it doesn't work quite like it used to. Before, it would come on all the time, even on small hills, and it always came on around 1900 rpm. Now, you really have to be trucking down a hill or coming off the freeway and downshift a couple gears to get it to go. Now it triggers around 2300 rpm. I am curious to know how the PCM knows when to trigger DFCO. I'm thinking it has something to do with the MAP, and maybe throttle position. Is there a way to get the DFCO to trigger sooner, or more often? Thanks.
