Tune out decel pop
I have an NPP exhaust with the fuse pulled, really like the sound other than the crackling on deceleration.
What should a tuning shop charge for just that change in the computer? Hopefully I can find a place that will do that 1 change... Thanks! |

https://www.camaro5.com/forums/data:...AAAElFTkSuQmCCHere's a screen shot from HPTuners of the fix for me. I disabled DFCO (decel fuel cut-off) by making the Enable ECT (engine coolant temperature) 414*F (so it doesn't happen). The default is 14*F. Like Ted said, it's not worth having a shop just change that - it literally takes a few seconds to make the change and about 45 seconds to flash the ECU.
There can be other factors like adaptive idle coastdown timing and timing, but this is the first and easiest approach to tackling the decel popping. |

Doubt a shop would charge much to make this change. I wouldn't advise disabling it as it'll impact mpg's |
