On the OBD1 LT1, does the RPM limiter work via with fuel cut off or ignition cut off?

Thanks guys. The reason for the question is that the LTCC system I just installed has a rev limiter leading me to think the stock limiter was by ignition and that by installing the LTCC, I had bypassed it.

What you want to do it get the limiter in the pcm set high and set the ignition based one lower.
