Anyone know Holley Commander 950's? programming?

Should have explained. "For now" I'm monitoring the O2 with a digi meter. It's a Bosch single wire. I don't have it hooked to the Pro-Jection 2D yet as I don't have the (optional) harness yet. It is designed to be runnable ??? with no O2 sensor.

One thing I'm concerned about is that I have headers, so it seems a "long way" from the collector to the head (through the bolts) and to the engine block.

Actually, I wasn't sure I wanted to try and run this thing. I may just get busy and install the temp sender tomorrow. I would have today, but by the time I got the replacement, if not temporary, return line in, and got the pressure issue resolved, my back was "done for the day."

I'm afraid the 67 has become a "test bed" of sorts.
