Pretty much, it's just basically an ignition cut... more commonly referred to as a 'two-step' rev-limiter...

Unless you are talking about traction control as well, whereby the answer is no, they are not all the same...

Unless your talking about launch control.

There are two tyes, ignition and fuel cut.

On an NA car, they are the basically the same.
On a FI car, its the difference between 1-3psi off the line, or 10-20psi. Ignition giving the later. But its also the difference between turbo turbo longevity. Being the former, fuel.

are there detrimental effects of running ignition cut on an mild 'bolt ons' NA engine?

Na. The downsides come from the engine pushing all the fuel into the turbo charger, where it tends to explode. This causes premature wear/failure of the turbo bearings/wheels/shafts.

Good, cos ignition cut sounds more fun than fuel cut.

edit - oh wait, logically this could be to the detriment of my cat?

Although i am using a metallic cat.
