Removing ECM, what's gonna be missing...

IF I take out the ECM and convert the engine management over to non-ecm hei, what functions throughout the car will be inoperable?

I know that the convertor needs to be wired so it will lockup, is there anything else?

You'll also need a new carburetor.

Cruise control won't work without regrounding.
