Turn off "decel fuel cut off"
According to chemistry, alcohol is a solution...

^ You'll also need to add some over-fuelling in the decel areas. Actually if you set it right the decel fuel cutoff can actually cause a good pop or two (but not a constant crackle) when fuel delivery starts again, apparently some of the 80s EFI Corvettes were known for this from factory.

Also the "Decel Enleanment Param" tables. cut off is only the 100% fuel cut down hill, but the DE stuff is what does the partial fuel cut that stops the crackle earlier. I'd start with the two 'factors' and see what effect that can have.

I never touched any of the decel stuff but my daily current and previous one both crackled when in overrun with the throttle slightly open 1-2%, crackle on command basically.

I have always wondered why it does it but my other 2 cars with low K engines don't with basically the same tune.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
