Also in using this scanner it says the left display is block learn-the numbers there stay at 105 or 106. The right display is Integrator it stays at 128-may vary a minor amout at full boost.Joe Lubrant burned the chip and I thought that he said the blm's were locked at 128. It seems neither is locked-the integrator stays locked almost at 128-the block learn seems to stay at 105 most of the time.What does this indicate? Thanks in advance from a learning GN fan!

Here's a good article by Ken Mosher (of TurboLink fame) on BLMs and Integrator:

Ooops....missed that.

Some chips (like Joe's) lock the BLM at WOT only, but not at cruise. A couple of chips are open loop all the time and so the blm is effectively "locked" there, as well. Otherwise once the engine is warmed up and at less than wot you should see the int bouncing up and down maybe 5-15 and the blm holding fairly steady so long as you don't change rpm or engine load. At wot the int should be locked at 128. The fact that your blm is 105 (at idle, I assume) means that the fuel pressure is a little higher than the chip was expecting. That's still okay, though, because the adjustment limits are probably 90-160 on the blm so you haven't run out of range and presumably you need the fuel pressure where you have it to match your boost level at wot. It's a little more complicated than that because there are actually 16 blms and even though the idle one, say, looks rich, some others can look lean. So long as they average to about 128 you are fine. As others said, the article at gnttype gives more info.
