Inducing dfco
 

Hey guys, my car (ford zx2) seems to have very specific parameters for dfco. It seems to only work when going from above 55mph and stops at 40mph and even if i keep the rpm above 2500 below 40mph it keeps the injectors on.

Is there any way to cheat these parameters or easily change them? Right now dfco seems pretty useless, as in my daily drive i can only dfco once :(

Any insight is appreciated, thanks in advance!

mwebb's right: most of the time, you're better off coasting.

For those rare times that DFCO is beneficial, you might want to check in on this thread to see what's brewing in terms of DIY DFCO:

My wife's 08 Avenger has DFCO also, but with a 4 sp auto. DFCO only engages above 60 mph, and fuel cuts in @55mph. However, I can extend it lower if I pull the shifter down into 3rd before slowing down to 55. Then it will continue to about 43mph.

Well i guess that coasting would be better, i was trying to get into the habit of keeping it in gear to reduce brake use more but now that i think about it i guess i should just lift off the throttle earlier and coast:D

Thanks for the input

Agreed with every1 when in a manual just coast engine off much more efficient, the only reason i use dfco is because of the auto tranny im not risking shutting off and the fact that in 4th gear of my auto tranny automatically switches into neutral while inducing dfco above 45mph

UPdate. I was specifically watching the speedo after pulling the gear selector into 3rd while keeping the DFCO engaged...and it stayed until 35mph before fuel flow resumed.
