Does that FI system adjust for altitude changes with a barometric sensor, or something? I would think that would be a must have living in the mountains.

and.. IMO.. you don't want to connect that computer to the internet, becasue if you do, it would not be the first time that MS did an 'automatic update' to your obsolete, but functioning, computer and made it never work again! (They did that to an NT pro system I'd been using for years... saying it was the last time they would 'provide a fixes' update; I bought their BS and let it happen.. that computer never booted up again after that 'upgrade'... It seems obvious to me that's another part of MS's approach, forcing us to buy NEW computers and with it of course, NEW OS...

Again, I'll cite the acceleration enrichment improvement of the HP EFI with updated s/w. There are probably more things like that. And that's an update for HP - no telling what was improved from original HP over the 950, but you can bet that there were several things.
Is the number of fuel and spark table cells the same between 950 and HP? Stock systems have more than even the HP.
And, like the old MS stuff, the 950 isn't supported with software updates any more. You may be OK - but you won't know what you're missing either.
To be honest, I've never programmed any EFI system so far but I did stay ay a Holiday Inn. I have read a little about it and I understand the concepts, just not the details.
The fuel map is looks like it's 16x16 to me.
Here's what they say about the HP EFI:
"Can be set to 31x31 or 16x16 with user adjustable axes. 8x8 Target Air/Fuel Ratio table"
There's an acceleration enrichment table, another one showing O2 sensor data, a table for temperature compensation and it features an internal datalogger that can be turned on with a switch.
Here's the entire C950 user manual. It seems to have quite an impressive capability to me. I'm sure the HP EFI is much better as far as better map resolution, and for used in boosted applications or NOS. The learning function probably makes tuning a lot simpler too.

Here's an example of the C950 engine parameters screen:
And a fuel map:
Here's the fuel in 3D
The spark map is similar:
And here's the acceleration enrichment table:
This is an example of what you get from the datalogger:
And here's some O2 sensor inputs...
