100% reproducible drama:

parked vehicle, 6K RPM

you get amazing exhaust pops and things feel like some sort of software cut?

this is all suspiciously close to 50% injector duty cycle (same 50% in TS long and on logic analyzer)

We really need to fix the idle hiccup bug just to make sure it's not the same issue #3269

We really need to fix that major fuel cut on decel #3225

@blundar says next time to logic analyze all 8 channels with crank cam and coils not just fuel

@stefanst is asking to rev much much slower next time and check if same or different outcome
