To get exhaust pops/burbles, you have to keep the fuel on and retard timing for a short while after lifting throttle. That's basically what the Jaguar engineers do on their F-Type.

While the ability to leave fuel on for a while after throttle lift is defined, Hondata doesn't allow any modification of timing during overrun conditions so while you can keep the fuel on, the corresponding tables that govern timing during throttle lift aren't defined.
