Anyone know Holley Commander 950's? programming?

At least you are no longer "flying blind". Like I said, why the h*** didn't Holley put a rich LED on the 2D box? There is one on their clumsy add-on O2 box for the analog system. With my 2D box, I had to tap into the O2 sensor wires to send to a Holley rich/lean indicator box.

The original system was designed by Autotronics (MSD) for Holley and it was a bit better in my opinion. Possibly Holley designed the 2D box in-house and seems they botched that. Your experience with it having a "mind of its own" is similar to mine. I suspect the pot's are erratic. I also suspect it is affected by RFI since the 2 times it went crazy at the exact same spot on the highway by road construction. "Crazy" is a technical term meaning it flooded the engine with fuel (slowed way down) and then the muffler exploded (both times).

There are a few setups to make in commissioning it. Insure your TPS is adjusted to give the correct signal at idle (~0.8 V I recall, but read manual). There is also a setting for small block or big block, which you do by a switch in the analog box and by connecting the pink(?) wire to gnd or +12V in the 2D box. The later makes it harder to switch between the analog and digital boxes since the pink wire is something else for the analog box. Don't spend excessive time trying to adjust the 3 knobs perfectly since whatever you do, you will end up having to tweak them once in a while to keep from stumbling, so keep the box close (but not in the sun since it can get real hot easily and act bad).
