Installation of aftermarket ecm
After I get my new engine I was going to get a aftermarket ecm such as the holley commander 950. Since this was designed for only fuel and spark management. What do I do about items such as cruise control and transmission control. Can I leave the old ecm in place to control everything else. Thanks for your time.

From Holley's site:
These systems are designed only for fuel and spark management. Items such as cruise control, transmission control, AC, ABS, etc are not controlled by the Commander 950.
