B/L INT Numbers

[Marteney, Steven J.]

Ignore this post if I'm wrong, but...
If you are looking at block learn's with a scanner, doesn't it ONLY display
the current block learn mult or int?  But, block learn's are tabular in
nature and the table is indexed by TPS and something else.  So, naturally,
if TPS changes you'll see the BLM,BLI change because it jumped to a
different spot in the table.  With constant TPS, the same table spot is used
and will only change if ECM deems it necessary.  Am I all wet?  (or green?)

I have seen mine change it each step (ie it is one different in each
frame).  This would require the current fuel mixture to of course be
off, and that is really what determines how fast it changes it.  If
the car is running steady state (constant speed/tps) it won't change,
but if the speed or tps changes odds are that the BLM/ints will need
to make an adjustment.   From what I can tell the BLM/ints were not
changing more than once per frame (7 aldl frames per second), I never
saw things jump more than the standard step they appeared to be using.
