I'm in the process of swapping in a new L29 454 engine with ported heads, reground cam, Edelbrock pro-flow manifold, injectors, and throttle body, and making it work with a 0411, currently with an L31 tune in it. I want to eliminate the ABS motor system under the hood and go with a Wilwood conventional proportioning valve. What needs to be done in the pcm to turn off the abs system?
