but when you say the "VE-table" are you talking about the fuel table?
If yes ,i can't do this because the cell value is "2"and I can't go down
...
And if I decrease this value to "1" the engine run bad.
where is the mistake.... 
Michele.
Yes, VE-Table = Fuel-Table.
My guess is that you have an sky-high Requiredfuel-value?
Try lower it to 1/5 of your current value and raise your whole VE-Table by 4 or 5 times.
Please post a .vemslog or .vemscfg !
