Hello everyone,
I’m still trying to get used to the forums. But I did some digging and couldn’t find anyone with an answer.

I want to do a 2-step tune. Or rev limiter or launch control, whatever term floats the boat. It’s my understanding (I’m very ignorant) that the factory rev limiter is the fuel cut-off type, initially designed to protect the catalytic converter. But, I’m looking to change that to ignition cut-off.

Is it possible? If it is possible, how can it be done? And if it requires an aftermarket ECU, where would I start looking?

Thank you in advance!
