    DFCO question

    Hi all,

    I've been reading up on DFCO, and I was wondering if there is a way in TP to show when DFCO is engaging.

    depends on the application. some masks have it setup in their datastreams already, other would need some ALDL response modification.

    or you can just watch BPW and when it drops to 0 suddenly, that would be DFCO.

    Thanks Rob,

    Of course I gave you no information whatsoever, so you couldn't read my mind or guess? ;) 7747 asdu.

    What I would like is to have a flag on the dash.

    I guess another way to do so is to watch the BLM shoot up all of a sudden...

    when in DFCO, BLM will lock to whatever it was before entering DFCO. INT should reset to 128 as well. you will see O2 voltage drop to 0/near 0.

    and i know i made a tutorial on the TP forum, but i could have sworn there was one locally as well.....

    Hey Rob, Found your post on http://forum.tunerpro.net/viewtopic.php?t=2094

    Nice primer. But what I'm looking for is how to create new create a DFCO Value that, for example, takes the "DFCO - Enable temp, TPS threshold, Map, RPM... Etc" and have a flag that shows if DFCO is enabled.

    Even having a flag that shows when BPW reaches 0 would be great...

    Thanks again...
