Unreadable, un-tuneable, both?
I'll settle for reading.

(What is meant by 'Black Box'? Just a stock GM PCM? Aren't they all?)

Most folks have some place like Blackbear Performance tune those. DIY tuners usually upgrade from the Black Box to the newer 0411 that GM came out with in the 2000s. IDK, if you can find an .xdf and .adx file for it you should be able to read and data log at least. I have no personal experience with these PCMs.

That's a problem with your computer, not with your ECM.

Truth be told, I've not been near the truck with it yet or the lap top that will be used for that. Just trying it on this lap top (that has a crap battery). Maybe it will work straight off the bat on the lap top I intend using (Win 7 with a good battery).
I'll still need the appropriate BIN though?

Higher priority is to see what Rock Auto have to say about replacing duff master cylinder....

Sorry for the confusion, I was referring to the PC not the PCM, (too many acronyms) ha ha.

No, it's OK - I got it.
I just didn't explain very well that it might not matter that this PC is being uncooperative as it's another PC that will be used. I only need it to work. Trying on this one is just nosiness to see how the pages/options/etc will look. Weather here is too wintery to get much done on the truck for now.

Replacement of master cylinder in hand. Next on the list?.... Dodgy phone charger lead. Fixing things - never ending...

Black boxes are tunable. They're not as good as a 411, but there's plenty of power locked up in that PCM of yours.

Apart from diagnostics and things like the cam sensor synch, the other thing I'd like to experiment with is ignition timing. LPG has an octane number of 100+, my timing will be based on 87 octane.

Even on 87 you can add some total timing. The real drivability gains come from bringing it in MUCH sooner.

What do you mean by much sooner?
Lower in the rev range? At lower MAPs (then bleeding it off)? Something else?

Yes to both, ha ha. Add spark, watch for Knock Counts, and adjust up or down. After adding spark add fuel which can/will reduce KCs too. It's best to have a WBO2 for this stuff.
