Why does VE/BLM need to be tuned?

[Mastiff]

Can anyone explain why it's better to have the VE table dialed in so the BLMs all come back at 128, as opposed to just letting the computer learn by itself and use BLMs that are off? Once the ECM is done doing its own learning and is stable, I don't see what the difference would be if the table was full of 128's or 145's.

The ECM is slower than an old computer with dos, that was before windows 95... if your at 128 then it does not have to adjust. 145 would be big adjustment and lean...

Other main reason is everything else like choke and PE (Power Enrichement) are all based off what BLMs are doing. So at 128 all other circuts/systems are working properly.
