Anyone know Holley Commander 950's? programming?

Well today I received the O2 harness (optional) from fleebay for about 20 bucks. It fits the sensor connector used in the Commander sensor.

So I installed the temp sender, and the O2 hookup. This was late this aft. and I havent had enough time on it to tell if things made a difference.

The troubling thing about this is that it seems erratic. It will run OK for awhile, then the next time you "leave" a stop sign, acceleration is balky. Sometimes hard to figure if it's rich or lean.

I'm beginning to think the CPU has problems. I've got the fuel pressure resolved, and would have thought that a stable 200 ohm resistor in the temp sender circuit would have AT LEAST made the system "predictable." (After all, many/ most? carbs are not temp compensated)

If the weather is nice tomorrow, I may get some "toon time" on 'er.

Hope that Commander upgrade kit gets here soon.
