Deceleration Fuel Cut Off

I've used the torque app and the scangauge on both my cars and found the torque gauges don't show DCFO but the scangauge does. I know both my cars have it so must be a problem with the torque programming.

I find I usually can't feel it kick back in unless I'm on a bit of a downhill.

I feel it sometimes, and sometimes I don't feel it. That goes both for cut-off and cut-on.

Thanks. Does Scangauge actually have a field called Dfco, or are you looking at reading and inferring from that?

I have a 2000 Accord V6 and definitely have DFCO as noted on the ScanGage II mpg. Rpm up to 2000 and let of the gas. With the automatic I can down shift all the way to first gear and keep DFCO as long as the rpm's don't drop below 1200.

0 Load = DFCO, you don't need a specific parameter for it.

[JockoT]

Right enough. On the ScanGauge Load or LOD is the percentage of power being generated and if the cut off is engaged that will be zero. At tick-over there will be some small amount of power or LOD displayed.

When you guys say load. You mean Engine Load or something else?

[puddleglum]

Yes engine load. Instant lhk will go to 0 as well or 99999 mpg.

I read that for automatics to enter dfco you have to be in d3. Does anyonr know if that's true? I haven't tested it yet. I'm worried if I shift into d3 whie driving I'll ruin the transmission
