Default Going to standalone. Can I remove everything?

Hi everyone!

I am moving over to a Holley Dominator EFI soon. I'm not planning on using the stock gauges. Planning on swapping to manual brakes and manual steering. Is there any reason for me to keep any of the stock modules/wiring in the car? I don't think there will be anything left for them to control.

You still need a PCM and BCM, the PCM is still required to provide pulses to fire the coil packs unless you are installing a distributor, which can be done.

The Holley Dominator can control coil packs.

My bad, I thought it was just a EFI system, so it must have inputs from the crank and cam sensors?

The Holley systems can control most systems depending on the one you buy. Engine control, trans, boost, nitrous.

BCM for doors and locks. RFA for key fobs?

No worries! I should have posted a link to it. Dominator EFI (holley.com)

It is a wild system. Something like 40+ inputs and 30+ outputs.

THAT is something I did not think of. Probably need the BCM for the windows too, right?

When you say manual brakes, are you talking about a setup with 2 master cylinders and a balance bar?

Something like this, but bigger so it can actually handle my C7Z iron brakes.

The electronic service manual from 15 years ago had a heading "Chevrolet/Geo", and then the Model of the vehicle.

Ah, that makes more sense. I wasn't sure if they sold the Corvette overseas under the Geo brand or something.
