Decel Fuel Cut

Post by Azula_Rx8 »

I’ve been out of the forums for a hot minute.

I opened Versatuner and noticed new definitions and crackle tunes that are editing the DFCO.
(I haven’t touched versatuner or my tune in 4 years)
Can somebody confirm the tables are working now?

I’ve reflashed my tune with the new ECU definition update, and I definitely can hear some burble and such after editing my DFCO, but logs show it’s not really sending any fuel on decel still.

As far as I know it’s still not fully operational. You need to lightly press the accelerator pedal to engage the crackle and pops in the 2 lowest load values of the tune.
