I'm trying to turn on fuel cut-off when I'm decelerating, I've upgraded the CAM so ofcoarse MAP is always higher and won't go low enough i believe to turn on DFCO

Problem is in the tune, I can't see DFCO, normally when I'd tune other cars like LT1's etc.. I see Deceleration Fuel Cut Off that referenced MAP/TPS, which is straight forward, however in this file for the 2000 impala, I don't see that.

All I see is Deceleration Enleanment tables, what should I modify, I want the fuel to completely cut and hard when I release the gas pedal and going down a hill, right now it only sometimes cuts fuel from what I see on the wideband, usually it just leans out a bit and thats all, so not sure which tables to touch or max out so its a hard fuel cut off.

Any help would be cool thanks.
