Hey guys,
Quick one today, I see that spark cut RPM limiters aren't possible with an LS1B PCM.
I'm just curious as to why this is?
Cheers, Soop.

Might be because there will be excess fuel.

Well yes, But i've always thought it's safe to cut the spark then the fuel?
I know its done allot with Japanese cars, and allot of 2-step launch control programs use spark cut limiters. I was simply curious as to whether or not its a hardware limitation with the LS1B PCM.

IDK if it's a limitation or by design.
