I'm not knocking the Holley system, just curious
After looking at the instructions, it seems a different distributor is required to get this system to control ignition timing?
The LCD screen/ability to fine tune without burning a new chip is nice.
Factory air cleaner retention is nice.
My tan Jeep, with a 350, has TBI. I am using a stock GM computer, it works fine, self learns, etc. I never thought of trying to fine tune it any more, I would probably mess it up

On this one, I have the GM TBI distributor, so the computer controls the timing. It has the knock sensor/ESCM to make that happen.
I have been working on a stock CJ7 with Howell TBI, it runs great, I just don't like being able to easily reuse the stock air cleaner housing

It uses the stock distributor/ignition system, so no integration there, but it runs great.
I'll have to see if my rich uncle Tommy will buy one of these Holley kits to install on one of his Jeeps
