Default lt1 tuneing help "rev limiter"

More help needed guys, I was looking through the pcm consants and noticed there were fuel cut off points between shifts. Some of these were set at around the same rpm the car actually data logged at. i know lt1s use fuel shut off for rev limiting so i dont wanna hit that can someone here set these up or tell me a good rpm to set at all the limiter points

One good thing for an aftermarket icm box like the 6al is that you can use it for the rev limiter. And just set the computer for higher rpms than you set the box for. That way spark gets cut off and not fuel.

Can I set rev limiter values over 7k rpm? I was thinking of setting everything to 7100 but wasn't sure if it would recognize it (7k roof for stock pcm)

Just because I misspelled tuning in the header doesn't mean you don't have to help.

You can set it to whatever you want but will still cut around 7k, depending on the PCM year..
