I believe you always want some value in Table 2. I used #5 for 400-3600 rpms adding balance to table #1 from #2. The idea is that there always has to be some VE in the adder table in order to have the VE lean out at high RPMs. If the ve adder table is zero, you cant reduce the VE after you have gone off the edge of the main table. 4000-4800 RPMs my adder would scale down like 45 @ 4000 35 @ 4400 and 25 @ 4800. Once youve done this you can leave the second VE table alone below 3600 rpm. Just work with the main VE table #1
