Has anyone, with cats still on their car, disabled this? I have had my LS1 EDIT for about a week and I am just playing around. I also have juice so I don't know if this would be wise. Running lean on the juice <img border="0" alt="[bomb]" title="" src="graemlins/gr_bomb.gif" /> .

 

I certainly wouldn't do it if I still had cats...

 

sometimes disabling it is needed, cats or not, to get the top end of the PE vs RPM table to respond to edit changes....been there.

 

I did it.
So far so good.
Only way I could stablize a/f
Now instead of it tanking to 10.8 it's stays at a nice 12:1 right where I want it.
Seeing as my target a/f is somewhat rich (blower-car) I figure my cats are safe.
Time will tell I guess.

 

Thank you for the information, I think I will play around. If I destroy my cats it will give me a good reason to do a full exhuast. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
