Question Question about using Holly or any LS EFI SYSTEMS and keeping stock gauges and more

Hello all,

As in the title, I am searching for info on keeping the stock gauges, ABS, and all other functions while upgrading the ECU. I have a LG-G5x3 cam and some other mods but the ECU cannot keep up with what I want to do. I do understand i need to upgrade the ECU however I hate the digital screen, I love the stock interior and I am trying my hardest to keep the Camaro looking stock.

If anyone has any links or advice on how to do this please advise, note this upgrade might be next year. I searched the forum however I have yet to find anything, I could have missed it. Sorry if I did.

EDIT: What I did find out - use new ECU and old ECU, have old ECU send data to the car and have new ECU run motor. I don't know how feasible this is, has anyone done something like this.
