Re: 87-89 350 TPI ESC Module

In my chiltons manual, it says that the ESC system(electronic spark control) is used in conjuction with the EST system(electronic spark timing) to reduce spark knock by retarding the ignition timing. A knock sensor, which is installed in the cylinder block, sends a signal to the ESC module and then in turn to the ECM, which then adjusts timing accordingly.

Re: 87-89 350 TPI ESC Module

If the ECM doesn't work, the engine won't run.
If you meant to ask what would happen if the ESC didn't work, you'd probably get knock from too much timing advance. Or false knock on the other hand, which would actually rob your engine of power randomly. It's hard to say which one.

Hope this helps.
Lou

No
Just keep the wiring to the gauge senders in engine .All you need is power to the coil and some way of making the fan and fuel pump run without the computer
