Anyone know Holley Commander 950's? programming?

I haven't called Holley, but it looks like you can get a "package deal" IE Holley will flash update the ECU, new software, and the complete wideband setup for 350 or so with shipping.

My plan is to do a "temporary" install, leaving the unused and unhooked low pressure pump in place and unplugged, so I can easily change back to carb. Run the system long enough to find out that it's at least functional, and then pull it off and if it's OK, send it in

I didn't realize that wide band (just sensors) were SO dammed expensive.
