Hello.

Basicall ve table multiplies 'FuelREQ' value for calculations. If your ve values are too high... go back and incerase your your fuel req, bu say 40%, then scale whole table by the same so the ratio is constant but actual ve values will be 40% smaller... or 50% or whatever you want to set it to

Change it in the constants. What is your req_fuel set to? I'm using 780cc injectors on a 2000cc engine. REQ_FUEL is 7ms and idle VE is about 14%. The actual idle pulse width is about 1.6ms

The VE entries can go up to 255. If you need numbers over 255 then up the req fuel value and rescale the VE table. How to do that is covered in the tuning section of the manual
