Connect and Cruise system with Holley 12.3

[csouth]

Hi Everyone,

I've read through a lot of posts here and there is some amazing information.

I'm hoping to get some direction/input on where I'm at on my build.

I have a 1971 Nova that I have the Speedtech Performance Pro Touring complete kit. I also have a a Chevy Performance connect and cruise LS376/525 with a T 56 Magnum transmission. The Nova has a 1969 Camaro dash assembly installed and I'm working on planning out the dash bezel and gauges. I've seen a lot of people use the Nova dash pad on the Camaro dash assembly and that is my goal.



My hiccup is figuring out what dash bezel to use. I was thinking of using the Dakota Digital HDX (or RTX) gauge kit with the console but I would have to purchase the dash bezel that either has the Camaro badging or put in the clock in the middle of the speedo and tach. I didn't really consider the Holley 12.3 dash since the whole connect and cruise kit was complete but I like the way options for the 12.3 dash bezel, which would remove the concern regarding the clock/Camaro badging.

If I go with the Holley 12.3 dash, will I have any issues with the connect and cruise? Am I replacing parts on the connect and cruise or will the Holley work with the system? I'm mechanically inclined but tuning is an area that I haven't adventured into at this point.

I see a lot of posts about the pros of the Holley if I want to add a supercharger in the future but I'm trying to figure out compatibility issues/concerns with using the Holley system?

Anyone done anything like this before that can help point me in the right direction or have any suggestions?

I don't think the Holley will do a direct integration, you will likely need the standalone version and have to tap into the connect and cruise harness for data. User Andrewb70 could tell you for sure. He does work for Holley.

I do not work for Holley, but I do have my own Holley EFI tuning business.

To answer the original question, the Holley dash is not compatible with the GM ECUs over CAN bus.
