As I understand it, the computer uses the block learn (or equiv) values to 
remember WHERE its adjustment left off. If say the car was fat, as in your 
case, then when the cell was learned to lean out, that value would be used at 
next startup (say blm was 110, it'd know that it had to remove that % fuel, 
and applied it to warm up) Thats how I understand it, and looks like how it 
is in my car. Its possible you have the injector constant a little off?

If I'm wrong, please correct me so I too may learn.
