Anyone know Holley Commander 950's? programming?

Thanks, Bill, but I'm in a little deep now.

I've got the Commander 950, for which I just ordered the upgrade flash

I've got parts of a Ferd MAP an also have a MAF sensor for a similar system.

AND I've got parts off a 95? Jeep MP system.

The Holley system will operate a "batch fired" MP setup, just not sequential.

What do you need for money/ equipment and software to re-program the GM stuff?


Also, I went down to NAPA and bought a controllable HEI module, AND they had the proper connectors for that module, about 15 and 21 bucks.

Last couple of days I've been arguing with the 2D system. Bear in mind it's used and dirty, and "temporary." Because of that, I first installed the Commander and left my Holley red pump in the rear (formerly for the carb) to feed the new Commander pump. The pressure was perfect, I didn't even have to adjust it.

So when I put the 2D on, I left the pumps as is. Turns out I cannot get the pressure below 30 psi, and the system is erratic. Runs good for awhile, then goes ?? I thought it was going rich, but at one point it backfired "through the carb," so THAT was a leanout.

I'm going to see about a new regulator diaphragm when I can confirm the part number. Holley, it seems to me, is a little short of SERVICE documentation on these units.

Also found the add--on O2 sensor harness for the 2D on ebay for cheap. So it can use the Commander 02 sensor.

By the way, the 4bbl Commander I have is the 900 cfm version.
